✨ New blog post: "STF Milestone 6: Improved Kotlin support"

#JUnit 6.0.0-RC1 improves JUnit's #Kotlin story by adding support for suspending functions, sequences, contracts and nullness annotations.

👉 marcphilipp.de/blog/2025/08...

Thanks to the @sovereign.tech fund for their support!

object ImprovedKotlinSupportTests {

val data = sequenceOf( // Sequence<T> support
arguments(1, Month.JANUARY),
arguments(12, Month.DECEMBER)
)

@ParameterizedTest
@FieldSource("data")
// suspending function support for coroutine testing
suspend fun test(value: Int, month: Month?) {
assertNotNull(month) // contracts to support...
assertEquals(value, month.value) // smart casts!
}

If you ever need to adapt a #JUnit3 TestSuite to run directly in #JUnit #Jupiter, it's actually possible with dynamic tests! 😎

Here's how I run the @⁠Inject TCK in the @SpringFramework.

Kudos to @marcphilipp.de for suggesting the dynamic test idea.
