compatibility with JUnit TestRule ?

See original GitHub issue

Is it possible to provide compatibility with JUnit TestRule ? Several frameworks provide test utilities as TestRules, to be used with @Rule or @ClassRule (exemple : DropWizard’s ResourceTestRule or DropwizardClientRule). Unless there is a way to import or bridge with these TestRules, fully switching to kotlintest is not convenient.

Thanks for the nice work,

I ended up doing the Rule code manually, as seen here: https://github.com/kategory/kategory/blob/e5813ebcb17a124ba6841718f8f2275f7ca99cb5/kategory-effects-android-architecture-components/src/test/kotlin/kategory/effects/data/LiveDataTest.kt#L20

I have a legitimate use case for supporting @Rule. The Android framework and its helper libraries rely on it for test behavior.

One example is the just released architecture-components: https://github.com/googlesamples/android-architecture-components/blob/master/GithubBrowserSample/app/src/test/java/com/android/example/github/ui/user/UserViewModelTest.java#L55

Without that rule it’s impossible to unitest that library, as it tries to find a Thread that doesn’t exist outside Android environments, and fails with NPE.
