argumentcaptor java mockito
// Consider you have a method: class A { public void foo(OtherClass other) { SomeData data = new SomeData("Some inner data"); other.doSomething(data); } } // Now if you want to check the inner data you can use the captor: // Create a mock of the OtherClass OtherClass other = mock(OtherClass.class); // Run the foo method with the mock new A().foo(other); // Capture the argument of the doSomething function ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class); verify(other, times(1)).doSomething(captor.capture()); // Assert the argument SomeData actual = captor.getValue(); assertEquals("Some inner data", actual.innerData);
