What is EasyMockSupport?

What is EasyMockSupport?

EasyMockSupport is a utility or helper class for test classes. It provides the following functionalities: replayAll() – Registers all the created mocks in one batch. verifyAll() – Verifies all the mock operations in one batch.

What does EasyMock verify do?

EasyMock verify() method is used to make sure that all the stubbed methods are being utilized and there are no unexpected calls. The behavior for unexpected calls changes for nice mock objects where it doesn’t throw any error. EasyMock verify() method is very similar to Mockito verify() method.

What does EasyMock expectLastCall do?

The API doc for EasyMock says this about expectLastCall() : Returns the expectation setter for the last expected invocation in the current thread. This method is used for expected invocations on void methods.

How do you call a mock?

3. Record the call.
4. Make sure the degree of call difficulty is in keeping with your reps’ experience.

How do you mock on EasyMock?

It uses the basic EasyMock concepts of expect, replay and verify.

1. Create mock instances for the objects you need to mock the method calls on, in this case the service and the stuffGetter .
2. Write expectations for the method calls using the expect method.
3. Replay the mock objects, in this case replay both of them.

How do you expect a void method to call in EasyMock?

When we use expectLastCall() and andAnswer() to mock void methods, we can use getCurrentArguments() to get the arguments passed to the method and perform some action on it. Finally, we have to return null since we are mocking a void method.

How do you mock a void in EasyMock?

Can we use PowerMock and EasyMock together?

Summary. PowerMock is a great extension to EasyMock and Mockito mocking frameworks. It helps us by extending our test cases to mock static methods too. You can checkout complete project and more EasyMock examples from our GitHub Repository.

What is jest FN?

The jest. fn method allows us to create a new mock function directly. If you are mocking an object method, you can use jest. fn method, the simplest way to create a mock function. This method can receive an optional function implementation, which will be executed transparently.

How do I use easymocksupport?

We can also use EasyMockSupport through delegation: Previously, we used static methods or annotations to create and manage mocks. Under the hood, these static and annotated mocks are controlled by a global EasyMockSupport instance.

How to inject mocks using annotations in easyeasymock?

EasyMock also supports injecting mocks using annotations. To use them, we need to run our unit tests with EasyMockRunner so that it processes @Mock and @TestSubject annotations. Let’s rewrite previous snippets:

What is recording and replay In EasyMock?

Once created, a mock is in “recording” mode, meaning that EasyMock will record any action the Mock Object takes, and replay them in the “replay” mode replay (…): switches a given mock to “replay” mode. Then, any action triggering previously recorded method calls will replay “recorded results”

What is expectlastcall() In EasyMock?

With expect (…), EasyMock is expecting the method to return a value or throw an Exception. EasyMock will complain about this, as it requires a call on expect (…).andReturn (…) if the method returns anything. If it’s a void method, we can expect its action using expectLastCall () like this: 5.2. Replay Order
