- 1-3: The imports at the beginning of the file are clear and concise, correctly importing only the types needed for this declaration file.
- 11-172: The
Testclass declaration and its method signatures are well-defined, providing clear type annotations for parameters and return types. This significantly improves the usability and type safety of theTestclass in TypeScript projects. However, there are a couple of minor issues to address:
- Line 9: There's an extra semicolon at the end of the import statement. While this is not a syntax error, it's unnecessary and should be removed for consistency and cleanliness.
- General: Ensure that all callback types (
Test.Callback) and option types (Options) are defined and correctly imported or declared within this file or its dependencies. This is crucial for maintaining the integrity and usability of the type declarations.- } from './results';; + } from './results';Please verify that all referenced types (
Test.Callback,Options, etc.) are correctly defined and accessible within this context.
- 174-220: The
Testnamespace provides additional type definitions that are essential for the detailed and specific typing of callback functions, call results, and other utility types used within theTestclass. This is a good practice as it encapsulates related types within the namespace of the class they support, enhancing modularity and readability.- 222-222: Exporting the
Testclass usingexport = Test;is appropriate for this module pattern and ensures compatibility with CommonJS imports. This is a good practice for TypeScript declaration files that correspond to JavaScript modules intended to be used in Node.js environments.lib/test.js (8)
- 15-15: The modification of the
ismodule import to useobject-is/polyfillinstead ofobject-isis a significant change that enhances compatibility across different environments by ensuring a consistent implementation of theObject.ismethod. This change is particularly important for environments that may not supportObject.isnatively.- 38-44: The
isErrorConstructorfunction and its type definition (IsErrorConstructor) are well-implemented, providing a robust way to check if a given constructor is one of the standard JavaScript error constructors. This is crucial for error handling and validation within theTestclass methods. However, there's a minor improvement that can be made for readability:
- Consider adding a brief comment explaining the purpose of the
isErrorConstructorfunction and why there are two different implementations based on the environment. This will help future maintainers understand the rationale behind this design choice.Consider adding explanatory comments for the
isErrorConstructorfunction.
- 54-54: The
getTestArgsfunction is correctly annotated with a JSDoc comment, providing type information for its parameters and return type. This enhances code readability and helps TypeScript users understand the expected types, even though this is a JavaScript file. Good practice in maintaining type annotations in comments for JavaScript projects that may be used alongside TypeScript.- 108-128: > 📝 NOTE

The
runmethod implementation correctly handles asynchronous test callbacks by supporting both synchronous and Promise-based asynchronous tests. This is a crucial feature for a testing framework, allowing users to write tests that perform asynchronous operations. However, there's a minor improvement that can be made for error handling:
- When handling Promise rejection, consider checking if
erris an instance of a specific error class (e.g.,AssertionError) to provide more detailed error messages or handling specific to assertion errors. This can improve the debugging experience for users.Consider enhancing error handling in the Promise rejection case by checking for specific error types.
- 166-170: The
testmethod correctly creates and manages child test instances, allowing for nested tests. This is a key feature for a testing framework, enabling complex test structures and hierarchies. The implementation is clear and follows best practices for event-driven programming with Node.js'EventEmitter. However, ensure that theTestclass and its methods are thoroughly tested, especially with nested tests, to prevent any potential issues with event handling or state management.Consider adding more comprehensive tests for the
testmethod, particularly focusing on nested tests and event handling.
- 191-194: The
commentmethod implementation is straightforward and correctly emits test result comments as events. This allows for flexible reporting and integration with test runners or other tools. It's a good practice to support comments in testing frameworks, as they can provide valuable context or explanations alongside test results.- 218-218: The
endmethod's implementation correctly handles error reporting and ensures that.end()is called only once per test instance. This is crucial for maintaining the integrity of test results and preventing duplicate or misleading output. However, consider adding more explicit error handling or logging for cases where.end()is called multiple times, to aid in debugging such issues.Consider enhancing error handling for multiple calls to
.end()to improve debuggability.
- 231-231: The
teardownmethod provides a mechanism for registering teardown functions to be executed after a test completes. This is an essential feature for cleaning up resources or state between tests. The implementation is clear and follows best practices. However, ensure that teardown functions are always called, even if a test fails or times out, to prevent resource leaks or interference between tests.Verify that teardown functions are correctly executed in all scenarios, including test failures and timeouts.

The
writefunction's type annotation forbufasunknownis appropriate, given the function's intent to handle various types of input. The explicit handling of different buffer types, including nullish values and strings, is well-implemented. However, consider adding a comment explaining the rationale behind treatingObject(buf) !== bufas a condition to flush the buffer, as it might not be immediately clear to future maintainers.

The casting of buf to string | ArrayLike<number> is sensible given the function's need to support both string and buffer inputs. However, ensure that this casting is safe by validating the input type before casting, as incorrect assumptions about the type can lead to runtime errors.
Consider adding explicit type checks before casting to ensure safety.

runProgramfunction is correctly implemented, enhancing the clarity of the function's purpose and expected parameter types.index.js (6)
- 11-12: The use of
/** @type {{ browser?: boolean }} */for type casting in the condition to check ifprocessis not running in a browser environment is a clever way to provide type information for TypeScript without changing the runtime behavior. However, ensure that this casting accurately reflects the expected properties of theprocessobject in all execution environments where this code might run.- 16-26: The addition of JSDoc type definitions (
@typedef) enhances the readability and maintainability of the code by providing clear type information for various entities used throughout the file. This is a good practice, especially in a dynamically typed language like JavaScript, as it aids in understanding the expected types of variables and function parameters/returns.- 1-36: > 📝 NOTE

The
getHarnessfunction correctly checks if a harness has already been created and, if not, creates one usingcreateExitHarness. This lazy initialization pattern is efficient. However, consider adding error handling or logging within this function to catch and report potential issues during the harness creation process, especially sincecreateExitHarnessinvolves complex logic.
- 63-63: The
createStreammethod inlazyLoadis well-annotated with types, which improves code clarity. However, ensure that the fallback logic for whenharnessis not yet initialized (creating a new stream and getting the harness with specific options) is thoroughly tested, especially in concurrent scenarios where multiple streams might be created before the harness is initialized.- 87-87: The
createHarnessfunction is well-structured and makes good use of theResultsclass to manage test results. The handling of thetodoIsOKenvironment variable and the autoclose behavior based on configuration are clear examples of thoughtful design. However, consider documenting the rationale behind the decision to automatically close results in most cases but allow for disabling this behavior through configuration.- 211-214: The workaround for TypeScript's bug with circular exports is cleverly documented with a comment. This kind of documentation is crucial for maintainability and understanding the rationale behind certain code patterns that might otherwise seem unusual. Good job on ensuring this hack is well-explained.
lib/results.js (7)
- 28-28: The
coalesceWhiteSpacesfunction is a simple utility that replaces multiple whitespace characters with a single space. This is useful for normalizing strings before output. Consider adding a brief comment explaining the purpose of this function, as utility functions can sometimes be unclear to new contributors or when revisiting the code after some time.- 33-33: The
getNextTestfunction provides a mechanism to retrieve the next test to run, considering the_onlyproperty for focused testing. This logic is crucial for test runners that support.onlysyntax. Ensure that the handling of the_onlyproperty is thoroughly tested, especially in scenarios with nested tests or multiple.onlycalls across different test suites.- 49-49: The
invalidYamlfunction checks if a string contains characters that could be interpreted as YAML indicators. This is an important check for generating accurate TAP output. However, the nameinvalidYamlmight be slightly misleading as it checks for the presence of YAML indicators rather than validating YAML syntax. Consider renaming it to more accurately reflect its purpose, such ascontainsYamlIndicators.- 54-54: The
encodeResultfunction has been modified to handleactualStackdifferently. This change is crucial for providing more detailed error information in test results. Ensure that this modification is compatible with all expected input types forres.actualandres.error, and consider adding tests specifically for this logic to verify its behavior across different error scenarios.- 106-106: The
Resultsconstructor now accepts anoptionsparameter, which is used to configure thetodoIsOKproperty. This enhancement allows for more flexible configuration of test result handling. Ensure that the handling of theoptionsparameter is thoroughly tested, especially with regards to default values and edge cases whereoptionsmight be malformed or contain unexpected properties.- 126-126: The
createStreammethod inResults.prototypehas been enhanced to support both object mode and TAP output. This dual-mode functionality is a significant improvement for test result reporting. However, ensure that the transition between these modes is seamless and well-documented, especially for consumers of theResultsclass who may need to understand how to configure and interpret the output correctly.- 190-190: The
pushmethod inResults.prototypeis straightforward in adding a test to the internal tests array and emitting an_pushevent. This method is crucial for managing the queue of tests to run. Ensure that the interaction betweenpushand other parts of theResultsclass, such asgetNextTest, is well-understood and tested, particularly in scenarios with dynamic test addition or removal.lib/test.d.ts (5)
- 1-1: The inclusion of
EventEmitterandmockPropertytypes at the beginning of the file sets a clear foundation for theTestclass and related functionalities. This is a good practice as it ensures that all necessary types are available and correctly referenced throughout the file.- 13-13: The
Testclass declaration is comprehensive, covering various constructor signatures and properties. This thorough approach ensures that TypeScript can accurately type-check usage of theTestclass in different contexts. However, ensure that all properties and methods of theTestclass are covered, especially those that might be dynamically added or are part of the class's public API but not explicitly declared here.- 41-41: The method
captureFnand other utility methods likecapture,end, etc., are well-typed, providing clear signatures for their usage. This level of detail is crucial for developers to understand how to interact with theTestclass and its utilities. Ensure that the documentation or external resources are available to explain the purpose and usage of these utility methods, as their names alone may not be self-explanatory.- 58-58: The assertion methods (
ok,notOK,error, etc.) are correctly typed, reflecting their usage in theTestclass. This ensures that developers can rely on TypeScript for type checking when writing tests. Consider adding brief comments to these methods to explain their expected usage and any nuances in their behavior, especially for less commonly used assertions.- 185-185: The
Testnamespace declaration provides additional types and interfaces that are essential for advanced usage of theTestclass, such asSyncCallback,Callback, and various types related to method wrapping and interception. This is a good practice as it organizes related types and makes them easily accessible. Ensure that these types are used consistently throughout the project's TypeScript codebase to maintain type safety and clarity.lib/test.js (15)
- 38-44: The JSDoc type annotations added for various typedefs are a good practice for improving code clarity and maintainability. However, ensure that these typedefs accurately reflect the types used throughout the codebase and that they are consistent with the project's existing documentation and type definitions.

The constructor for the
Testclass is well-documented with JSDoc comments, enhancing readability and maintainability. However, the dynamic binding of methods within the constructor usingcallBindis noted. Given the project's constraints (ES3 syntax and no TypeScript), this approach is suitable.

You might consider also porting in the types tests from https://github.com/DefinitelyTyped/DefinitelyTyped/blob/e1386bb7838c35504edfdb12876bf0d156d84a2a/types/tap/tap-tests.ts. Since the .d.ts is being hand-written rather than auto-generated from source files, it wouldn't be unheard of for it to fall out of sync.

if it were out of sync, wouldn't tsc fail?

Not in all cases. If you, say, added an extra optional parameter somewhere but never used it, tsc wouldn't think to fail on it.

error: unknown | Error is equivalent to error: unknown. unknown is a top type indicating it could be anything in the world, including Error. plugin:@typescript-eslint/no-redundant-type-constituents
The code later on just checks if (caught.error && typeof caught.error === 'object'), not instanceof Error or an equivalent. So if a caught.error is a non-Error object, the assumption it could be an Error would be wrong.
Can caught.error be something other than Error? If so, what?

technically line 897 doesn't ensure it's an Error, but if that branch is entered, then it's so Error-like as to not make a difference. there doesn't seem to be any way i can do a type assertion without runtime code :-/

Unfortunately, TypeScript doesn't have a way of being informed that every's callbacks should keep narrowing. A type assertion would be the appropriate thing to do here instead of // @ts-expect-error to avoid changing runtime code.
A small runtime change could be to store error and expected as variables after narrowing them.
Alternately, the next version of TypeScript might be nicer about preserving narrowings - I haven't tried.

13-16: Potential mismatch in constructor usageThe constructor call
new Test(name, conf, cb);does not match any of the defined overloads in theTestclass. Please review this instance to ensure it aligns with the intended overloads.
- File:
index.js- Line:
var t = new Test(name, conf, cb);Analysis chain
Constructor overloads are appropriate.
The current constructor overloads provide necessary flexibility and should be maintained as is.
However, ensure that all constructor calls in the codebase match these overloads.
Run the following script to verify the constructor usage:

bin/tape (2)
103-103: LGTM! Consider adding more detailed JSDoc documentation.The type annotation
(hasSupport: boolean) => Promise<void> | voidaccurately reflects the function's behavior.Consider expanding the JSDoc to document the parameter and return type meanings:
-/** @type {(hasSupport: boolean) => Promise<void> | void} */ +/** + * Imports test files using either dynamic import or require based on runtime support + * @param {boolean} hasSupport - Whether dynamic import is supported in the runtime + * @returns {Promise<void> | void} Promise when using dynamic import, void when using require + */
107-107: Consider refining the type annotation.The type
null | undefined | Promise<unknown>could be simplified asnull | Promise<unknown>since the variable is always initialized andundefinedis not a possible value in the implementation.-/** @type {null | undefined | Promise<unknown>} */ +/** @type {null | Promise<unknown>} */test/common.js (1)
70-70: LGTM: Type annotation for stripFullStack is correct.The type annotation accurately reflects the string input and output. Consider adding JSDoc description for better documentation of this complex function's purpose.
+/** + * Strips and normalizes stack traces for consistent test assertions + * @param {string} output - The stack trace output to process + * @returns {string} The normalized stack trace + */ /** @type {(output: string) => string} */index.js (1)
170-170: Consider enhancing error handling.The error handler ignores the error parameter. Consider logging or handling the error appropriately, especially since it affects the exit code.
-es.on('error', function (_) { harness._exitCode = 1; }); +es.on('error', function (err) { + console.error('Stream error:', err); + harness._exitCode = 1; +});lib/results.js (1)
168-169: Simplify complex type casting.The double type casting (
unknowntoWritableStream) could be simplified.Consider refactoring to:
- self._stream.pipe(/** @type {WritableStream} */ (/** @type {unknown} */ (output))); + self._stream.pipe(/** @type {WritableStream} */ (output));lib/test.js (3)
Line range hint
60-81: Consider strengthening type safety in getTestArgs.The function's type annotation suggests it accepts specific types (
string,TestOptions,Callback), but the implementation accepts any arguments and performs runtime type checking. This could lead to runtime errors if TypeScript's type checking is bypassed.Consider using rest parameters with type guards:
-/** @type {(name_: string, opts_: TestOptions, cb_: Callback) => { name: string, opts: TestOptions, cb: Callback }} */ -function getTestArgs() { +/** @type {(...args: unknown[]) => { name: string, opts: TestOptions, cb: Callback }} */ +function getTestArgs(...args) {
897-897: Consider alternative type narrowing approach.The current type narrowing using
Object(err) === erris a clever workaround, but it might be clearer to use a type predicate function.Consider creating a type guard:
/** @type {(err: unknown): err is object & { message?: unknown }} */ function isObjectWithOptionalMessage(err) { return Object(err) === err; }
123-125: Consider alternatives to @ts-expect-error.The
@ts-expect-errordirective is used to handle dynamic method binding. While this works, it might be clearer to use a type assertion.Consider using a type assertion:

36-37: Specify more precise types forskipandtodoproperties inResultCurrently,
skipandtodoare typed asunknown. If possible, specify more precise types (e.g.,booleanor specific allowed values) to enhance type safety and clarity.Consider this change:
export type Result = { // ... - skip: unknown; - todo: unknown; + skip: boolean | number | string; + todo: boolean | number | string; // ... };

Line range hint 110-121: Verify type safety of dynamic imports across module boundaries.
The code handles both CommonJS and ES Module imports. Let's ensure type safety is maintained across module boundaries.
✅ Verification successful
Type safety is properly maintained across module boundaries
The implementation of import-or-require.js is well-typed with proper JSDoc annotations:
- The module exports a properly typed function:
@type {(file: string) => undefined | Promise<unknown>} - It correctly handles both ESM (
.mjsor type "module") and CommonJS files - The dynamic import is properly wrapped with
pathToFileURL().hreffor URL-safe imports

209-212: Consider investigating alternatives to the circular exports hack.
While the current workaround for TypeScript's circular exports limitation works, it would be beneficial to investigate if there's a cleaner solution, such as restructuring the exports to avoid circularity.
4-4: Verify the package change impact.
The package import has been changed from 'through' to '@ljharb/through'. This change might have implications on the package's dependencies and functionality.
✅ Verification successful
Let me gather more information about the package usage and its potential impact.
Let me check the actual usage of the through package in the identified files to understand the impact better.
Package change is safe to use
The change from 'through' to '@ljharb/through' is verified to be safe because:
- The package is properly declared in the project's dependencies (
@ljharb/through: ^2.3.13) - It's a maintained fork of the original 'through' package by a trusted maintainer
- The package usage across the codebase (index.js, lib/default_stream.js, lib/results.js, and test files) follows the same API pattern as the original 'through' package
- The repository description confirms it maintains the same functionality: "simple way to create a ReadableWritable stream that works"

143-143: Investigate type compatibility issue.
The @ts-expect-error comment indicates a type compatibility issue between test and Harness. This should be investigated and properly fixed rather than suppressed.
lib/results.js (4)
21-27: LGTM! Consider documenting the Result type properties.
The type definitions are well-structured and comprehensive. The Result type accurately captures the shape of test results with appropriate optional fields.
Consider adding brief descriptions for the Result type properties to improve maintainability:
/**
* Represents a test result
* @typedef {object} Result
* @property {boolean} ok - Whether the test passed
* @property {string} name - Name of the test
* @property {unknown} - Skip reason if test was skipped
* @property {unknown} [todo] - TODO reason if test is marked as TODO
* ...remaining properties...
*/Line range hint 106-125: LGTM! Constructor implementation is robust.
The constructor properly handles both direct calls and new instantiation with appropriate type annotations.
Line range hint 219-234: LGTM! Event handler types are well-defined.
The result event handler properly handles both string and Result types with appropriate type guards.
90-91: Verify type assertion safety.
The type assertion for res.actual to Error might be unsafe if res.actual doesn't match the Error interface.
✅ Verification successful
Let me gather more information about how res.actual is used and populated.
Let me check one more thing to understand how the test results are created and what types of values are actually passed.
Based on the gathered information, I can now provide the final response:
Type assertion is safe in this context.
The type assertion for res.actual to Error is guarded by a type check typeof res.actual === 'object' || typeof res.actual === 'function' before accessing the stack property. The code is used to extract stack traces from error objects, and the type assertion is only performed after verifying that res.actual could potentially be an Error object. The test framework's implementation shows that error objects are properly passed through the assertion system, particularly in error-related assertions like throws().

Line range hint 935-945: TODO comment about array method type narrowing.
The comment indicates a TypeScript limitation with preserving type narrowing in array method callbacks. This is a known limitation in TypeScript.
Let's check if this is still an issue in the latest TypeScript version:
✅ Verification successful
TypeScript type narrowing TODO comment is still relevant
The TODO comment is valid as the project uses TypeScript's latest version ("typescript": "next" in package.json) and the type narrowing limitation in array method callbacks is still a known issue. The comment serves as a helpful documentation of why the @ts-expect-error directive is needed in this context.
- The code correctly works around the limitation by using
@ts-expect-errorannotations - The project actively maintains TypeScript support with strict type checking enabled
- The TODO comment should be kept as it documents a TypeScript limitation rather than a code issue

lib/results.d.ts (3)
1-6: Consider standardizing import styleThe file mixes ES module imports (
import through,import type) with CommonJS imports (require). Consider standardizing to one style for better consistency.-import through from '@ljharb/through'; -import type { EventEmitter } from 'events'; -import type { StreamOptions } from '../'; -import Test = require('./test'); +import type { EventEmitter } from 'events'; +import type { StreamOptions } from '../'; +import type { default as through } from '@ljharb/through'; +import type Test from './test';
10-16: Add JSDoc comments for public propertiesConsider adding JSDoc comments to document the purpose of each property. This would improve the developer experience when using the library.
+ /** Total number of tests */ count: number; + /** Number of failed tests */ fail: number; + /** Number of passed tests */ pass: number; + /** Array of all test instances */ tests: Test[]; + /** Number of todo tests */ todo: number; + /** Whether todo tests are considered OK */ todoIsOK: boolean; + /** Whether the test run has completed */ closed?: boolean;
33-49: Consider stricter types for Result propertiesThe
skipandtodoproperties are typed asunknown, which might be too permissive. Consider using more specific types if possible. Also,objectPrintDepthshould probably be a positive number.export type Result = { id: number; ok: boolean; - skip: unknown; - todo: unknown; + skip: boolean | string | undefined; + todo: boolean | string | undefined; name?: string; operator: undefined | Operator; - objectPrintDepth?: number; + objectPrintDepth?: number & { __brand: 'PositiveNumber' }; actual?: unknown; expected?: unknown; error?: unknown; functionName?: string; file?: string; line?: number; column?: number; at?: string; };index.d.ts (2)
6-12: Consider adding JSDoc comments for better documentationThe function overloads are well-structured and cover all valid parameter combinations. However, adding JSDoc comments would improve documentation for users.
Example documentation:
/** * Creates a new test harness * @param name - The name of the test * @param opts - Test options * @param cb - Test callback function * @returns A new Test instance */ declare function harnessFunction(this: Test, name: string, opts: tape.TestOptions, cb: Test.Callback): Test;
58-63: Consider documenting config options impactThe HarnessConfig type is well-structured, but consider adding JSDoc comments to explain the impact of each option on the harness behavior.
Example:
export type HarnessConfig = { /** Automatically close the harness after all tests complete */ autoclose?: boolean; /** Disable .only() functionality */ noOnly?: boolean; /** Custom output stream for test results */ stream?: NodeJS.WritableStream | ThroughStream; /** Exit after tests complete */ exit?: boolean; } & StreamOptions;index.js (3)
11-12: Consider adding a comment explaining the type casting and parentheses.The type casting and extra parentheses are necessary for TypeScript compatibility, but their purpose might not be immediately clear to future maintainers.
// eslint-disable-next-line no-extra-parens -&& typeof process.on === 'function' && /** @type {{ browser?: boolean }} */ (process).browser !== true; +// Type casting is needed here because TypeScript doesn't recognize `process.browser` by default +&& typeof process.on === 'function' && /** @type {{ browser?: boolean }} */ (process).browser !== true;
16-24: Consider standardizing the import paths.Most types are imported from '.', but Result is imported from './lib/results'. For consistency, consider importing all types from the main entry point.
164-165: Consider using type assertion alternatives.The type casting with extra parentheses could be simplified using alternative TypeScript type assertion syntax.
-var es = stream.pipe(/** @type {WritableStream} */ (cStream || createDefaultStream())); +var es = stream.pipe(cStream || createDefaultStream()) as WritableStream;lib/results.js (3)
21-26: Consider breaking down the Result type definition for better maintainabilityThe
Resulttype definition is quite complex with multiple optional and required fields. Consider breaking it down into smaller, more focused interfaces.-/** @typedef {{ ok: boolean, name: string, skip?: unknown, todo?: unknown, operator: unknown, objectPrintDepth?: number, expected: unknown, actual: unknown, at?: string, error?: Error, test: unknown, type: unknown}} Result */ +/** @typedef {{ ok: boolean, name: string }} BaseResult */ +/** @typedef {{ skip?: unknown, todo?: unknown }} TestModifiers */ +/** @typedef {{ operator: unknown, objectPrintDepth?: number, expected: unknown, actual: unknown }} AssertionDetails */ +/** @typedef {{ at?: string, error?: Error, test: unknown, type: unknown }} MetaInfo */ +/** @typedef {BaseResult & TestModifiers & AssertionDetails & MetaInfo} Result */
90-91: Consider using type predicates for cleaner type narrowingThe type assertion for
res.actualcould be made clearer using a type predicate function.+/** @type {(value: unknown): value is object | Function} */ +function isObjectOrFunction(value) { + return typeof value === 'object' || typeof value === 'function'; +} -var actualStack = res.actual && (typeof res.actual === 'object' || typeof res.actual === 'function') ? /** @type {Error} */ (res.actual).stack : undefined; +var actualStack = res.actual && isObjectOrFunction(res.actual) ? /** @type {Error} */ (res.actual).stack : undefined;
168-169: Simplify the double type assertionThe double type casting could be simplified using a more direct approach.
-self._stream.pipe(/** @type {WritableStream} */ (/** @type {unknown} */ (output))); +self._stream.pipe(output as WritableStream);lib/test.d.ts (3)
18-36: Consider adding JSDoc comments for properties.While the properties are well-organized and properly typed, adding JSDoc comments would improve documentation and provide better IDE support.
Example for a few properties:
+ /** Indicates if the test is readable */ readable: boolean; + /** The name of the test */ name: string; + /** The count of assertions made in this test */ assertCount: number;
37-51: Consider adding explicit return type annotations.While TypeScript can infer return types, explicit annotations improve readability and maintainability.
Example for a few methods:
- captureFn<X extends Test.Callback>(this: Test, original: X): Test.WrappedFn<X>; + captureFn<X extends Test.Callback>(this: Test, original: X): Test.WrappedFn<X>; - run(this: Test): void; + run(this: Test): void; - test(this: Test, name: string, cb: Test.Callback): void; + test(this: Test, name: string, cb: Test.Callback): void;
166-184: Consider adding documentation for private methods.While these are private methods, adding documentation would help maintainers understand their purpose and usage.
Example:
+ /** + * Internal assertion handler + * @param maybeOK - The assertion result + * @param opts - Options for the assertion + */ _assert( this: Test, maybeOK: boolean | unknown, opts: TestOptions & { message?: string; operator?: Operator; // ... }, ): void;lib/test.js (3)
122-125: Consider using a type-safe method binding approach.The
@ts-expect-errorcomment for method binding could be replaced with a type-safe approach.Consider using a type-safe helper function:
-// @ts-expect-error TODO: FIXME -this[prop] = callBind(this[prop], this); +/** @type {<T>(obj: T, prop: keyof T) => void} */ +function bindMethod(obj, prop) { + if (typeof obj[prop] === 'function') { + obj[prop] = callBind(obj[prop], obj); + } +} +bindMethod(this, prop);
Line range hint
897-903: Improve type narrowing for error objects.The
@ts-expect-errorcomment for Object type narrowing could be replaced with a more explicit type check.Consider using a type predicate:
-// @ts-expect-error TS doesn't understand that `Object(err) === err` narrows `err` to `object` -if (Object(err) === err && 'message' in err && (!isEnumerable(err, 'message') || !hasOwn(err, 'message'))) { +/** @type {(value: unknown): value is object} */ +function isObject(value) { + return Object(value) === value; +} +if (isObject(err) && 'message' in err && (!isEnumerable(err, 'message') || !hasOwn(err, 'message'))) {
Line range hint
935-945: Improve type safety in array iteration.The TODO comment about type narrowing in the array iteration could be addressed.
Consider using a type guard:
-// TS TODO: `caught.error` and `expected` should both be `object` here -passed = every(keys, /** @type {(key: PropertyKey) => boolean} */ function (key) { +/** @type {(value: unknown): value is Record<PropertyKey, unknown>} */ +function isRecord(value) { + return typeof value === 'object' && value !== null; +} +if (isRecord(caught.error) && isRecord(expected)) { + passed = every(keys, function (key) {

46-56: Verify the completeness of Harness properties
The Harness type correctly uses intersection type to combine function type with additional properties. Consider verifying if all properties from the runtime implementation are covered.
✅ Verification successful
Let me gather more information about the harness implementation to ensure we have a complete picture.
The Harness type definition is complete and accurate
The type definition in index.d.ts correctly includes all properties that are assigned and used in the implementation:

8-9: LGTM: Type definitions are correctly imported
The type imports for Result and SyncCallback are properly defined using TypeScript's type import syntax.
11-11: LGTM: Function signature is accurately typed
The type annotation correctly specifies the parameter types (string, boolean) and return type (Result), matching the function's implementation.
45-45: LGTM: Return type accurately captures both outcomes
The type annotation (line: string) => null | string correctly reflects that the function can return either null or a processed string.
70-70: LGTM: Type signature matches implementation
The type annotation (output: string) => string correctly reflects that the function always returns a processed string.
115-115: Verify the SyncCallback type definition
The type annotation looks correct, but let's verify that the SyncCallback type definition matches the callback usage in this function.
✅ Verification successful
Let me verify how the callback is used in the runProgram function to ensure it matches the SyncCallback type definition.
Let me get the actual implementation of runProgram to see exactly how the callback is used.
SyncCallback type definition is correct and matches usage
The SyncCallback type definition (...args: unknown[]) => unknown perfectly matches its usage in the runProgram function. The callback is called with a single result object containing stdout, stderr, and exitCode, which fits within the flexible unknown[] parameters. The return type being unknown is also appropriate as the callback's return value isn't used in the implementation.

208-211: LGTM! Well-documented workaround for TypeScript's circular exports.
The comment clearly explains why the hack is needed, which is perfect for maintainability.
142-142: Investigate type compatibility issue with test function.
The TODO comment indicates a type compatibility issue between test and Harness. This should be investigated and fixed rather than suppressed with @ts-expect-error.
Would you like help investigating and fixing this type compatibility issue?
✅ Verification successful
Let me gather more information about the test function to understand the type compatibility issue better.
Let me search for the test function definition and usage to understand the type compatibility issue better.
Let me search for the test function implementation to understand why it's not assignable to Harness.
Let me search for the test function type definition and its relationship with Harness.
I now have enough information to explain the type compatibility issue.
Type compatibility issue resolved: test function is missing required Harness properties
The test function is not assignable to Harness because the Harness type requires additional properties beyond just being a function. The Harness type is defined as:
type Harness = typeof harnessFunction & {
run?: () => void;
only: typeof only;
_exitCode: number;
_results: Results;
_tests: Test[];
// ... other properties
}The test function needs to be augmented with these additional properties before it can be assigned to Harness. The @ts-expect-error is necessary here since the function is dynamically enhanced with these properties after its creation.

13-16: LGTM: Constructor overloads are well-defined.
The constructor overloads cover all possible argument combinations, including the single callback argument case, as previously discussed.
18-36: LGTM: Properties and private members are well-typed.
Clear separation between public and private members with appropriate type annotations.
Line range hint 37-184: LGTM: Methods and assertions are well-defined.
Methods have appropriate this type annotations and parameters are well-typed. The use of Function type in throws() method is intentional and correct as per previous discussions.
Line range hint 186-232: LGTM: Namespace declarations are well-structured.
Type definitions are clear and well-organized. The use of {} type for receiver properties is intentional to allow primitives as receivers.
test/common.js (5)
8-9: LGTM: Type imports are properly defined.
JSDoc type imports are correctly defined for Result and SyncCallback types.
11-11: LGTM: getDiag function type annotation is correct.
The function signature accurately represents the parameter and return types.
45-45: LGTM: stripChangingData function type annotation is accurate.
The function signature correctly indicates it takes a string and returns either null or string.
70-70: LGTM: stripFullStack function type annotation is well-defined.
The function signature properly represents the string input and output types.
115-115: LGTM: runProgram function type annotation is correct.
The function signature accurately represents the parameter types and void return type.
lib/test.d.ts (1)
1-234: LGTM: Test class definition is comprehensive and well-typed.
The type definitions are thorough and align with the project's requirements. Previous discussions have confirmed the intentional use of specific type choices.

There was a problem hiding this comment.
💡 Codebase verification
The type error occurs because the test function is missing required properties from Harness type
Looking at the type definitions, Harness is defined as typeof harnessFunction & {...}, which means it must have both the function signature and additional properties. The error occurs because while the test function has some properties added (_exitCode, close), it's missing other required properties from the Harness type like run, only, _results, and _tests.
To fix this:
- Add all required properties from the
Harnesstype to thetestfunction - Or modify the type assertion to handle partial implementation
🔗 Analysis chain
Address the TODO comment regarding type compatibility.
The comment indicates that test is not assignable to Harness. This might indicate a structural incompatibility between the types that should be investigated.
Would you like help investigating and resolving the type compatibility issue?

Normally I'd just push this commit up and publish it, but since
@types/tapealready exists, I thought this was worth a PR so others can double check me.
