Mockito参数捕获器和only（）

Question

I found, that whenever I use verify with only() - to check that invocation was just one time - ArgumentCaptor can't capture a value (I have null in value).

For instance: verify(delegate, only()).call(captor.capture());

What are the reasons for it? Or it is just a bug?

Answer 1

Not sure what only() is actually doing, but Mockito.times(1) works, while the only() fails.

My guess is when you call Mockito.when initially it's counted as the first invocation in case of only() , but not in Mockito.times
