You own instantiator which only needs to implement IClassInstantiator. Here, I don’t want the document received by voteForRemovals to be equals, I want it to be the exact same class instance coming from the cache. It is a source not a binary compatibility. amd

JUnit Testing Using EasyMock

This circumstance imposes some logical restrictions on development. It contains four stages. This reference card will guide you through the creation of unit tests with JUnit and EasyMock.

In this case only the methods added with addMockedMethod s will be mocked mockedMethod in the example. Used to indicate a test method. This is used for parameter driven tests. In order to be easympck to test code in isolation, those dependencies need to be removed to prevent any impact on test code by the dependant code. Similar idea is used when using spring to inject dummy implementations into JUnit. This can be handy to make sure a thread-unsafe mocked object is used correctly.

Unexpected method call documentAdded “Wrong title”: Arrays are by default since 3. EasyMock is a mock framework which can be easily used in conjunction with JUnit. If the method call is executed too often, the Mock Object jubit, too: In order to avoid code duplication I need to develop an abstract class for the eaysmock. All of these libraries are compliments to any of the above Unit Testing frameworks I listed, including jUnit.

Finally, calling checkIsUsedInOneThread mock, true on a mock will make sure juniit mock is used in only one thread and throw an exception otherwise. Methods in the Abstract Container are self explained, so there is no need to stop on them in detail. This phase records the expected behaviors of the mock ane.
