EasyMock matcher for class data type

Question

I am having nightmares with the syntax for this and easymock:

public void foo(Class clazz);

EasyMock.expects(object.foo(EasyMock.isA(???)));


        

Answer 1

You're attempting to verify a generic type that will be erased at runtime anyway.

Use a capture object instead:

Capture<Class<?>> classCapture = new Capture<Class<?>>();
EasyMock.expect(object.foo(EasyMock.capture(classCapture)));

// ... other test setup ...

Assert.assertEquals(classCapture.getValue(), String.class);

Answer 2

I think the following will also work as an expect statement if you don't want to use a Capture:

EasyMock.expects(object.foo(EasyMock.isA(String.class.getClass())));
