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 .

If you need these, statically import thse Matchers into your test code:.

Take a look at source code of AbstractExpectations. We create a mock Subscriber that should receive the message. Which probably says that oneOf means that I expect that fheat 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 with parameters 2 and 2. We will test that a Publisher sends a message to a single registered Subscriber.

Except for the invocation count and the mock object, all clauses are optional.

Conditions are represented as states of state machines. An expectation that uses parameter matchers must use chsat “with” method to wrap every parameter, whether a matcher function or a literal value.

Software jMock 2 Java 1.

The same matcher specifies that the actual value of the argument must be the same object as the expected value. The intial state is optional.

This is a tighter constraint shet equalbut is usually what you want for arguments that pass references to behavioural objects. In tests I can see using one and in other there is oneOf.

The examples above assume that the mock object is stored in an instance variable. We create a Publisher to test. JUnit 3 JUnit 4 Other.

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. Is any difference in using one or oneOf in JMock?

Expect a Sequence of Invocations

The result of each factory method must be wrapped by a call to the with method. The invocation is not expected at all. For example, the code above would accept any of the following argument values: The code below, for example, specifies that the method “doSomething” must be called with one argument of value 1. Judicious use of the any constraint ensure that your tests are flexible and do not require constant maintenance when tested code changes.


Matchers can be composed to create a tighter or looser specification. The argument matches all of the Matchers m 1 to m n. The stringContaining matcher is especially useful for testing string contents but isolating tests from the exact details of punctuation and formatting.

Email Required, but never shown. To define looser constraints, specify all arguments as matchers within with clauses:. More matchers are defined as static methods in the org. Maybe it’s just my missunderstanding of the the definition. If not specified, the state machine starts in an unnamed initial state. A Mockery creates mock objects and checks expectations that are set upon those mock objects. Expectations can be interspersed chet calls to the code under test.

A test can contain multiple expectation blocks. You can give an expectation as many inSequencewhenwill and then clauses as you wish. Stack Overflow works best with JavaScript enabled.
