EASYMOCK DOCUMENTATION PDF

The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall. Switches all registered mock objects (more exactly: the controls of the mock objects) to replay mode. For details, see the EasyMock documentation. Why. Great testing includes isolation. Most parts of a software system do not work in isolation, but collaborate with other parts to get their job done. In a lot of.

EasyMockSupport is a class that exist to help you keeping track of your mock. If ClassUnderTest gets a call for document removal, it asks all collaborators for their vote for removal with calls to byte voteForRemoval String title value. The correct result of amount.

To work well with generics, this matcher and isNull Class can be used in these three ways: If more than one mock can be assigned to the same field then this is considered an error. Expects a float array that is equal to the given array, i. This is the old version of strictMock String, Classwhich is more completion friendly. The ExchangeRate interface was small and simple enough that I could have easily written the mock class manually.

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. A failure in a test involving a mock object is a lot more likely to docmentation a failure in the method under test than in one of its dependencies. Unchecked exceptions that is, RuntimeExceptionError and all their subclasses can be thrown from every method.

You can set back the default one with setDefaultInstantiator. This interface contains two methods: Positive return values are a vote for removal. The failure occurs immediately at the first method call exceeding the limit:.

Easier testing with EasyMock

Behavior A second test Let us write a easymocj test. For backward compatibility, this property can change the default. This checking is not performed by default. It is also possible to specify a changing behavior for a method.

I have been using EasyMock to unit test some web-based classes without requiring the presence of the app server and I am very impressed.

Exactly the same as anyObject but prevents typing issues for the much used String type. Before ; import org. So the code will need to be recompiled. The same mock can be assigned more than once If no mock can be assigned to a field, skip the 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: Available for String s.

For specifying return values, we wrap the expected call in expect T value and specify the return value with the method andReturn Object returnValue on the object returned by expect T value. As an example, we define voteForRemoval “Document” to return 42 for the first three calls, throw a RuntimeException for the next four calls, return once. This kind of mock object is sometimes called a fake.

A given mock still can be made thread-safe by calling makeThreadSafe Object, boolean. Instead of calling expect T value to retrieve the object for setting the return value, we may also use the object returned by expectLastCall. This accounts for the many different ways a parser is allowed to pass text into a ContentHandler. Sometimes we would like our mock object to return a value or throw an exception that is created at the time of the actual call.

If the thought of writing all the mock object classes you might need is intimidating, look at EasyMock, a convenient Java API for creating mock objects dynamically. If I need to change some detail of the expectation, then I call EasyMock. So, we want to make sure addDocument is notifying Collaborator by calling documentAdded with the right title in argument.

Not only is it well crafted and easy to use. This is why we do TDD. You can throw any kind of exception you like — checked, runtime, or error — as long as the method signature supports it. Expects a long argument greater than the given value.

Let’s look at the test line by line.

Getting Started

If it’s not the case, or if you can’t do otherwise because of some development constraints, documentaton the solution:. To avoid the repetition of mock.

It also enhances communication in the TestCase for it exposes the expected calls on the MockObject right where you need it. The method eqException must create the argument matcher with the given Throwable, report it to EasyMock via the static method reportMatcher IArgumentMatcher matcherand easymoxk a value so that it may be used inside the call typically 0null or false.

Then, inject these mocks to the fields of every class annotated with TestSubject. It’s actually fairly complex, and it might well contain bugs. But once in a while, you will want to match you docuumentation in a different way. If you use Maven, the final required dependencies will look like this:.
