Argument captor mockito

Question

I have been doing a bit of reading around argument captor and the more I read about it, the more I get lost. Can someone take the pain of explaining it with an example?

According to docs, this is deprecated. You should use factory method forClass(Class) to create captors instead to avoid NullPointerExceptions. see here

Example:

  ArgumentCaptor<Person> argument = ArgumentCaptor.forClass(Person.class);
  verify(mock).doSomething(argument.capture());
  assertEquals("John", argument.getValue().getName());

Thanks for the information, Rachel but I am more interested in understanding how it works. After reading couple of blogs, I am confused as to what's the right way of using it. So, I'd you could explain it with an example, it would be great. Thanks – user123 Feb 07 '13 at 20:50

Thank you, that helps. Never came up when I was searching for it. – user123 Feb 07 '13 at 21:23

The no-arg constructor of the ArgumentCaptor class is deprecated. ArgumentCaptors themselves are certainly NOT deprecated. Indeed, they are an extremely useful technique. – Dawood ibn Kareem Feb 08 '13 at 04:51
