In the past, we’ve talked extensively about JMockit and Mockito. In this tutorial, we ‘ll give an introduction to another mocking tool – EasyMock. EasyMock Tutorial, EasyMock JUnit 5 example, EasyMock vs Mockito, EasyMock mock interface and classes, EasyMock @Mock, @TestSubject annotations. EasyMock + requires Java and above; EasyMock requires Java Just add EasyMock and Dexmaker as dependencies of the apk project used to.

This usually happens when you want to test a method that calls some others in the same class. To avoid the repetition of mock.
JUnit & EasyMock tutorial with a code examples
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: You might even be a disciple of TDD and haven’t done your implementation yet.
If it’s not the case, or if you can’t do otherwise because of some development constraints, here’s tutorlal solution: Ezsymock is available in the Maven central repository. You can pre-define the behavior of your mock objects and then use this mock object in your code for testing.
From there, I will highly suggest you have a look at the samples and the full documentation to get a fair overview of EasyMock. Unexpected method call documentRemoved “Does not exist”: If you use Maven, the final required dependencies will look like this: I have chosen the AbstractContainer class for the demonstration of JUnit tests, because in context of the application we have two realizations of this class.
It is possible to create a mock by calling one of its constructor.
However, since it extends a serializable class, this class might have defined a special behavior using for instance writeObject. Here is the example above, now using annotations: In this case only the methods added with addMockedMethod s will be mocked mockedMethod in the example.
If the method call is executed too often, the Mock Object complains, too: The replay method is called to make the Mock object available. Let us write tutkrial second test. As an example, we consider the following expectation: Survey Most Productive year for Staffing: The method has to be called in record state after the call to the Mock Object for which it specifies the Throwable to be thrown. You set this new instantiator using ClassInstantiatorFactory.
On top of that, since EasyMock 3.
It also enhances communication in the TestCase for it exposes the expected calls on the MockObject right where you need it. On a Mock Object returned by mock the default behavior for all methods tuyorial to throw an AssertionError for all unexpected method calls.
Expectation failure on verify: However, for a partial mock, if these methods are not mocked explicitly, they will have their normal behavior instead of EasyMock default’s one.
The pros are that the arguments found in EasyMock. EasyMock can save a lot of legwork and make unit tests a lot faster to write. My current expectation is not testing what I want. Enterprise Implementation in Java. Expecting an Explicit Number of Calls Easymockk to now, our test has only considered a single method call.
EasyMock tutorial – Getting Started
Private methods cannot be mocked. The next test should check whether the addition of an already existing document leads to a call to mock.
So, you need to mock the stock market service that returns dummy values without hitting the real server. It is a good idea to exclude Cglib since Dexmaker is used instead. The times method defines how often the Mock object will be called.
This can be change for a given mock if makeThreadSafe mock, false is called during the recording phase. For this purpose you can use the EasyMock testing framework. Create project and classes Create a new Java Project called com.
