JUnit 5 Assertions.assertThrows doesn't work if the block calls a suspend function, because the (Java) function isn't inline. What do people do here? Write their own version?

You should add the kotlin-test-junit5, it has inline assertFails

Hmm I'm seeing assertFailedWith in kotlin.test, a library I don't use. Can I just use a few assertions from this library without totally rewriting all my tests?

[octylFractal]

yes, they're meant to just be cross-platform compatible, so the kotlin-test ones are platform independent, but on JVM can use JUnit / AssertionError

[David Glasser]

Great. Wasn't sure if I have to switch to using their annotations and such too
