This is because sinon.spy() does not replace the method with a spy. It is a wrapper around the method. So, if you want to use sinon.spy() to replace the method with a spy, you need to do16var spy = sinon.spy();17object.method = spy;18Now, the test will pass. However, this is a bit of a pain because you need to change the code to insert the spy. This is where sinon.stub() comes in. It allows you to replace the method with a spy:19var stub = sinon.stub(object, 'method');20object.method();21assert(stub.called);22stub.restore();
