So it means that the IntentFilter parameter will be compared using equals. Sometimes, it is necessary to have a Mock Object that checks the order of only some calls. 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. For details, see the EasyMock documentation.

There are two differences between a strict Mock Object and a normal Mock Object: To match an actual method call on the Mock Object with an expectation, Object arguments are by default compared with equals(). Expect any int but captures it for later use. In record phase, you may switch order checking on by calling checkOrder(mock, true) and switch it off by calling checkOrder(mock, false). Since EasyMock 2.5, by default a mock is thread-safe. Verifies that no unexpected call was performed. For Below image shows the console output when the above JUnit test is executed. Expects a float array that is equal to the given array, i.e. Have a look at the javadoc. have the same length, and each element has to be equal. As the name suggests, it will expect the method to be called with.. well, any object :). by default since 3.5 compared with Arrays.equals(). Switches the given mock objects (more exactly: the controls of the mock objects) [method call]).andReturn ( [result]) for each expected call call mock. EasyMock provides a special check on the number of calls that can be made on a particular method. But that fails with this: Expects a byte argument less than the given value.

Expects a float that has an absolute difference to the given value that A class mock can also be serialized. For details, see HashSet is an implementation of a Set. three different ways. We will first a few classes and the dependencies to mock, then we will write a test for it. After calling replay, it behaves like a Mock Object, checking whether the expected method calls are really done. Expects a long argument greater than or equal to the given value. You can also have a look at the samples We will see how to perform all these steps in section 4. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, mocking of instance void method is working without calling 'expectLastCall' method, AssertionError Unexpected method call when unit testing. Expects a double that has an absolute difference to the given value that This method as same effect as calling verifyRecording(Object) Creates a mock object, of the requested type, that implements the given interface 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(). Interesting idea. To specify that the exact same instance is needed for this call, we use the method Here is the example above, now using annotations: The mock is instantiated by the runner at step 1. Working on improving health and education, reducing inequality, and spurring economic growth?

Expects an int that does not match the given expectation. This method is needed to define own argument expect(routerFactory.addFailureHandlerByOperationId(J_TASKER_START_RUN_ID, instance::validationError)).andReturn(routerFactory); Where instance is the JTaskerHandler class instance under test. Creates a mock object, of the requested type and name, that implements the given interface If we do not want to keep track of all mocks in the test, we can use EasyMockSupport to replay all mocks at once. This method is used for expected invocations on void Another less desirable solution might be to 'capture' the method instead of 'expecting' it, then the captured argument would have to have a way to call/trigger it . EasyMock void method javaunit-testingtestingjuniteasymock 68,754 Solution 1 You're close.
