How do you test a void on 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 check if a method returns void?
How to verify that void methods were called using Mockito
- The class under test is never mocked.
- The dependencies of the class under test need to be mocked.
- By calling a method on a mock object we will mock that method call.
- In your test, first perform the action under test then call verify() not the other way around.
What is EasyMock verify?
Summary. 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 expect() method tells EasyMock to simulate a method with certain arguments. The andReturn() method defines the return value of this method for the specified method parameters. The times() method defines how often the Mock object will be called.
What does EasyMock Replay do?
The replay method is used to pass the mock from recording (where you record the method you expect to be called) to replaying state (where you actually test).
What assert in void method?
Whenever we write unit test cases for any method, we expect a return value from the method. Generally, we use assert for checking if the method returns the value that we expect it to return, but in the case of void methods, they do not return any value.
How to mock a void method In EasyMock?
EasyMock expect() method can’t be used to mock void methods. However, we can use expectLastCall() along with andAnswer() to mock void methods. EasyMock void method. 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.
What is EasyMock verify () method?
EasyMock Verify method is used to verify that all the stubbed methods are called and there are no unexpected calls on the mocked object. EasyMock verify () method has the same effect as calling verifyRecording (Object) and verifyUnexpectedCalls (Object) methods.
What is an EasyMock object?
Up to this point, we have seen a mock object as a single object that is configured by static methods on the class EasyMock. But many of these static methods just identify the hidden control of the Mock Object and delegate to it. A Mock Control is an object implementing the IMocksControl interface.
How do I replay a mock In EasyMock?
Replaying the Mocked Method Lastly, we’ll use the EasyMock.replay () method to change the mock to “replay” mode, so that the recorded actions can be replayed when called: Consequently, when we call the test method, the custom behavior defined should be executed.
