Deep stubbing in Mockito

Posted on 2 mins read

Next version of Mockito, my favorite mocking/stubbing framework, will provide deep stubbing. This kind of test code will become possible:

``java @Test public void canStubOneLevelDeep() { OutputStream out = new ByteArrayOutputStream();

SocketFactory socketFactory = mock(SocketFactory.class, RETURNS_DEEP_STUBS);


} ```

Notice the two chained calls in a when clause. Isn’t it cool? I think that’s cool.

I can make tests clearer in case of poorly designed production code. And who doesn’t write poorly designed code sometimes? I do more often than not. So why not have at least clearer tests?

It would be even cooler if we could get rid of the ulgy (very ugly?) RETURNS_DEEP_STUBS artefact and let the when clause sort things out on its own.

Hey, have you noticed I use Fest Assert, the best assertion library?
