EasyMock : Documentation

Expects a string that contains the given substring. Tell documentatiion the mock should be used in only one thread.

Here is the test without the definition of the Mock Object: In the latter case, our code sample would not compile: Extending or delegating to EasyMockSupport is useful but not mandatory.

This is the old version of mock Classwhich is more completion friendly. Listing 8 uses EasyMock. Creates a mock object, of the requested type and name, that implements the given interface or extends the given class Note: You set this new instantiator using ClassInstantiatorFactory.

T – the interface that the mock object should implement. A failure in a test involving a mock object is a lot more likely to be a failure in the method under test than in one of its dependencies. First, it uses a strict mock so that order is required. We were about to implement our own Mocking based on reflect.

Instead of calling expect T value to retrieve the object for setting the return value, we may eqsymock use the object returned by expectLastCall.

Setting a property will change the entire EasyMock behavior. It is a source not a binary compatibility. Unchecked exceptions that is, RuntimeExceptionError and all their subclasses can be thrown from every method. Expects a comparable argument greater than the given value. You have been warned. Changing Behavior for the Same Method Call It is also possible to specify a changing behavior for a method.

The same mock can be assigned more than once If no mock can be assigned to a field, skip documwntation field silently If the mock cannot be assigned to any field, skip the mock silently If two mocks can be assigned to the same field, return an error Fields are searched recursively on the superclasses Note: And even if it did by some miracle return ExchangeRatewhat happens when I need to mock an instance of a different interface?

Easier testing with EasyMock

To define the new argument matcher, we implement the interface org. If you would like a strict Mock Object that checks the order of method calls, use EasyMock. Test ; import com. The answer is mock objects. There are a couple of predefined argument matchers available. Returns the expectation setter for the last expected invocation in the current thread.

T – type returned by the expected method Parameters: When you use matchers in a call, you have to specify matchers for all arguments of the method call.

You can use regular expressions to be even more explicit with EasyMock. The pros are that the arguments found in EasyMock. Elliotte Rusty Harold Published on April 28, Listing 4 tests this:. It means that you cannot record your own behavior for these methods.

The workaround is usually to call a constructor when creating the mock. Expects a double array that is equal to the given array, i.

The next step is just as surprising. However, I don’t need an additional test for this.

Truth be told, Listing documentatio failed the first time I ran it, as tests are wont to do. Contains methods to create, replay and verify mocks and a list of standard matchers. So, we want to make sure addDocument is notifying Collaborator by calling documentAdded with the right title in argument.

This can be handy to make sure a thread-unsafe mocked object is used correctly.

Just mock the concrete class. All used matchers should be serializable all genuine EasyMock ones are Recorded parameters should also be serializable Multithreading During recording, a mock is not thread-safe.
