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 .

A test can create multiple state machines and each state machine can have multiple states. The argument is any value. Cheat sheet says that: Expectations can be interspersed with calls to the code under test. If not specified, the state machine starts in an unnamed initial state.

Matchers can be composed to create a tighter or looser specification. The JUnit 3 and JUnit 4 integration layers automatically assert that all expectations have been satisfied. For example, the code above would accept any of the following argument values: The following code specifies that the method “doSomething” must be called with an argument that is not equal to 1.

The argument is not null. The stringContaining matcher specifies that the expected argument must be a string that contains the given substring.

In older versions of jMock and JUnit 4 you can use the JMock test runner, which is less flexible than the Rules mechanism shown above. You can give an expectation as many inSequencewhenwill and then clauses as you wish.

jMock – Matchers

Well this finally make sense: Most of the time expectations specify literal parameter values that are compared for equality against the actual parameters of invoked methods. As a rule of thumb, use equal for value objects and same for behavioural objects. Return a new iterator over elements v 1 to v n on each invocation. This is a JUnit 3 test case but apart from the test case class the code will be the same when using any test framework for which jMock 2 does not have an integration layer.

Tests written with JUnit 4 do not need to extend a specific base class but must specify that they use jMock with the RunWith attribute, create a JUnit4Mockery that reports expectation failures as JUnit 4 test failures, and store the Mockery in jmocck instance variable.

jMock 2 Cheat Sheet

The allOf matcher specifies that the actual argument must meet all of the matchers given as arguments. The Subscriber interface looks like this: Arrays are treated as a special case: We want to test the Publisher, which involves testing its interactions with its Subscribers.

The most commonly used matchers are defined in the Expectations 1 class:. Stack Overflow works best with JavaScript enabled. Is any difference in using one or oneOf in JMock? The anyOf matcher specifies that the actual argument must meet at least one of the matchers given as arguments. The invocation is expected at least min times and at most max times.

Loose parameter constraints are defined by specifying matchers for each parameter. The following clauses constrain invocations to occur within specific states and define how an invocation will change the current state of a state machine. This is used to make tests more explicit and so easier to understand. Changes the state of state-machine to the named state when the invocation occurs. The invocation is not expected at all.

jMock – Expect a Sequence of Invocations

Finally we create a message object to jmocck. A Publisher sends messages to zero or more Subscribers. Sometimes, however, you will need to define looser constraints over parameter values to clearly express the intent of the test or to ignore parameters or parts of parameters that are not relevant to the behaviour being tested.

We create a Publisher to test.

LoganMzz 1, 2 12 Software jMock 2 Java 1. Allowing or ignoring should be chosen to make the test code clearly express intent. The question is if there is any difference between this keywords or it means equaly the same thing.

To expect a sequence of invocations, write the expectations in order and add the inSequence sequence clause to each one. The following code specifies that method “doSomething” must be called with two Strings, the first must be null and chrat second must not be null.

We create a mock Subscriber that should receive the message. The most commonly used matcher is equalwhich specifies that the received argument must be equal jomck a given value.

Judicious use of the any constraint ensure that your tests cheta flexible and do not require constant maintenance when tested code changes. The following code specifies that the method “doSomething” must be called with a string that either contains the text “hello” or the text “howdy”. Post as a guest Name.
