JMOCK CHEAT SHEET PDF

JMock expectations oneOf VS one difference Is any difference in using one() or oneOf() in JMock? In cheat sheet mentioned before there is also example. Appendix A. jMock2 Cheat Sheet Introduction We use jMock2 as our mock object We’re using JUnit (we assume you’re familiar with it); jMock also. jMock 1 Documentation Stubs, Expectations and the Dispatch of Mocked Methods in jMock 1 3; Mocking Classes with jMock 1 and CGLIB 4 Cheat Sheet .

Arrays are treated as a special case: The set of matchers is extensible 1 so you can write new matchers to cover unusual testing scenarios. Sign up using Facebook. Null values are checked beforehand, so it is safe to specify equal null or apply the matcher to a null actual value.

The context mocks out the objects that the Publisher collaborates with in this case a Subscriber and checks that they are used correctly during the test. Changes the state of state-machine to the named state when the invocation occurs. More matchers are defined as static methods in the org.

Hseet as a guest Name. This is used to make tests more explicit and so easier to understand.

Expect a Sequence of Invocations

The invocation is expected exactly n times. The code below, for example, specifies that the method “doSomething” must be called with one argument of value shert. Finally we create a message object to publish.

The following code specifies that the method “doSomething” must be called with an argument that is not equal to 1. To test interactions between the Publisher and the Subscriber we will use a mock Subscriber cbeat. We first set up the context in which our test will execute. You don’t have to explicitly verify the mock objects in your tests.

Getting Started

The most commonly used matcher is equalwhich specifies that the received argument must be equal to a given value.

For example, the code above would accept any of the following argument values: We will test that a Publisher sends a message to a single registered Subscriber.

The argument matches all of the Matchers m 1 to m n. Judicious use of the any constraint ensure that your tests are flexible and do not shete constant maintenance when tested code changes.

Expectations can be interspersed with calls to the code under test. If the expected calls were not made, the test will fail. A Publisher sends messages to zero or more Subscribers.

Invocations that are expected in a sequence must occur in the order in which they appear in the test code. Sign up or log in Sign up using Google. The argument is not null. If a mock object is stored in a local variable, the variable shret be declared as final so that it can be referred to from within expectation blocks see below.

More matchers are defined as static factory methods of the Hamcrest Chsat class 2which can be statically imported at the top of the test code. The following code specifies that method “doSomething” will be called with one argument that refers to the same object as expected.

Take a look at source code of AbstractExpectations. The result of each factory method must be wrapped by a call to the with method.

Which probably says that oneOf means that I expect that could be more invocations of method add and in this case there are two invocations one of them is with parameters 1 and 1, and second sheef parameters 2 and 2.

The intial state is optional. This is useful for ignoring arguments that are not relevant to the scenario being tested. The not matcher specifies that the sheer argument must not cueat a given matcher.

If not specified, the state machine starts in an unnamed initial state. The argument is null.
