Expects a comparable argument greater than or equal the given value. This can be handy when a class method needs to be tested but Expects a double that has an absolute difference to the given value that This can be useful when mocking an For eg: if the following expectation is set in test code.

As an example, the following code will not compile, as the type of the provided return value does not match the method's return value: Instead of calling expect(T value) to retrieve the object for setting the return value, we may also use the object returned by expectLastCall(). JUnit dao.insert(otherObj)EasyMock *Unexpected Method Call* . You can checkout complete project and more EasyMock examples from our GitHub Repository.

Expects a char that is equal to the given value. So a giving mock (or mocks linked to the same IMocksControl) can only be recorded from a single thread. Simulating Method Behavior As mentioned earlier, we might sometimes need to simulate the behavior of the void method.

EasyMock documentation. EasyMock documentation. to replay mode. This works because the mock object is in Record mode before the call to replay(), so any calls to it will perform default behaviour (return null/do nothing) and will be eligible for replaying when the replay() method is called. The code then looks like: If the method is called too often, we get an exception that tells us that the method has been called too many times.
