kotlin and ArgumentCaptor - IllegalStateException

Question

I have a problem with capturing the Class argument via ArgumentCaptor. My test class looks like this:

@RunWith(RobolectricGradleTestRunner::class)
@Config(sd         


        

Answer 1

Another approach:

/**
 * Use instead of ArgumentMatcher.argThat(matcher: ArgumentMatcher)
 */
fun  safeArgThat(matcher: ArgumentMatcher): T {
    ThreadSafeMockingProgress.mockingProgress().argumentMatcherStorage
        .reportMatcher(matcher)
    return uninitialized()
}

@Suppress("UNCHECKED_CAST")
private fun  uninitialized(): T = null as T

Usage:

verify(spiedElement, times(1)).method(
    safeArgThat(
        CustomMatcher()
    )
)
