Extensions for Junit5 for Kotlin programming language
Creates instances of sealed classes for @Parametrized
tests
Usage:
@ParameterizedTest
@SealedClassesSource
fun test(item: SomeClass)
Can handle:
- nested sealed classes
- singletons
object
- empty constructors
- constructors made out of primitive types
You can pass in a TypeFactory
for creating custom instances like for mocking
You can extend the DefaultTypeFactory
for creating custom instances while reusing the creation of constructors with single paramter constructors with basic types and empty constructors.
sealed class Fruit {
object Orange : Fruit()
object Banana : Fruit()
data class Apple(color: String) : Fruit()
}
class FruitTypeFactory : DefaultTypeFactory() {
override fun create(what: KClass<*>) = when (what) {
Apple::class -> Fruit.Apple(
color = "red"
)
else -> super.create(what)
}
}
Filter:
You can filter out a few values by using the names attribute.
sealed class Family {
class Mother: Family()
class Father: Family()
sealed class Children: Family() {
class Son: Children()
class Daughter: Children()
sealed class GrandChildren: Children() {
class GrandSon: GrandChildren()
class GradDaughter: GrandChildren()
}
}
}
@ParameterizedTest
@SealedClassesSource(names = ["Mother", "Daughter", "GrandSon"])
fun test(item: Family)
Or you can turn this around by setting the mode attribute to EXCLUDE
@ParameterizedTest
@SealedClassesSource(names = ["Mother", "Daughter", "GrandSon"], mode = SealedClassesSource.Mode.EXCLUDE)
fun test(item: Family)
