Overview

Related Stack Overflow post: What use is @TestInstance annotation in JUnit 5?

Add another use case for TestInstace.PER_CLASS in Kotlin, which is, using regular simple class methods as the method factory for @MethodSource (which is used for parameterized tests):

@ParameterizedTest
@MethodSource("generateStrings")
fun `Test strings`(argument: String) {
    check(argument.isNotEmpty())
}

private fun generateStrings() = listOf(
    "java",
    "kotlin"
)
