Mockito + Catch Exception + AssertJ - BDD Style!

MyTest.java

import com.googlecode.catchexception.MyException;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;

import static com.googlecode.catchexception.apis.BDDCatchException.caughtException;
import static com.googlecode.catchexception.apis.BDDCatchException.when;
import static org.assertj.core.api.BDDAssertions.then;
import static org.mockito.BDDMockito.given;

@RunWith(MockitoJUnitRunner.class)
public class MyServiceTest {

	@Mock
	private OtherService otherServiceMock;

	@InjectMocks
	private MyService myService;

	@Test
	public void testDoThat() {

		given(otherServiceMock.bar()).willThrow(new MyException());

		when(() -> myService.foo());

		then(caughtException()).isInstanceOf(MyException.class);
	}

}

Does this support when(someOtherObject).doSomethingWhichCallsMyMockDoSomething(); ? Or are exceptions only caught on the object given to when() ?

How can you do the same thing but with a void method?

@brobert83 : for void methods, you should write doThrow(new MyException()).when(otherServiceMock).bar().
