End-to-End Testing Source

Overview

This is a mock source for testing the Airbyte pipeline. It can generate arbitrary data streams.

Mode

Continuous Feed

This is the only mode available starting from 2.0.0.

This mode allows users to specify a single-stream or multi-stream catalog with arbitrary schema. The schema should be compliant with Json schema draft-07.

The single-stream catalog config exists just for convenient, since in many testing cases, one stream is enough. If only one stream is specified in the multi-stream catalog config, it is equivalent to a single-stream catalog config.

Here is its configuration:

Mock Catalog Type Parameters Type Required Default Notes
Single-stream stream name string yes Name of the stream in the catalog.
stream schema json yes Json schema of the stream in the catalog. It must be a valid Json schema.
Multi-stream streams and schemas json yes A Json object specifying multiple data streams and their schemas. Each key in this object is one stream name. Each value is the schema for that stream.
Both max records integer yes 100 The number of record messages to emit from this connector. Min 1. Max 100 billion.
random seed integer no current time millis The seed is used in random Json object generation. Min 0. Max 1 million.
message interval integer no 0 The time interval between messages in millisecond. Min 0 ms. Max 60000 ms (1 minute).

Legacy Infinite Feed

This is a legacy mode used in Airbyte integration tests. It has been removed since 2.0.0. It has a simple catalog with one data stream that has the following schema:

{
  "type": "object",
  "properties":
    {
      "column1": { "type": "string" }
    }
}

The value of column1 will be an increasing number starting from 1.

This mode can generate infinite number of records, which can be dangerous. That's why it is excluded from the Cloud variant of this connector. Usually this mode should not be used.

There are two configurable parameters:

Parameters Type Required Default Notes
max records integer no null Number of message records to emit. When it is left empty, the connector will generate infinite number of messages.
message interval integer no null Time interval between messages in millisecond.

Exception after N

This is a legacy mode used in Airbyte integration tests. It has been removed since 2.0.0. It throws an IllegalStateException after certain number of messages. The number of messages to emit before exception is the only parameter for this mode.

This mode is also excluded from the Cloud variant of this connector.

Changelog

The OSS and Cloud variants have the same version number. The Cloud variant was initially released at version 1.0.0.
