How can I use Mockito for advanced mocking techniques?

Mockito offers several advanced features like argument captors, custom answers, and verification modes. What specific technique are you interested in?

Can you explain how to use argument captors?

Sure! Argument captors allow you to capture arguments passed to mocked methods for further assertions. You can create an ArgumentCaptor instance and use it in your tests.

How do I set up an ArgumentCaptor in my test?

You can set it up by creating an instance of ArgumentCaptor for the type of argument you want to capture, then use the 'capture()' method after the method call.

Can you give me a code example?

Absolutely! Here's a simple example:

ArgumentCaptor<String> captor = ArgumentCaptor.forClass(String.class);
verify(mockedList).add(captor.capture());
String capturedArgument = captor.getValue();
