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 .

In tests I can see using one and in other there is oneOf. The following code specifies that the method chheat must be called with a string that contains the text “hello” and the text “world”.
Arrays are treated as a special case: To define looser constraints, specify all arguments as fheat within with clauses:. The following code specifies that the method “doSomething” must be called with two arguments, the first of which is equal to 1 and the second of which is ignored in this test. By convention the Mockery is stored in an instance variable chet context. Well this finally make sense: If not specified, the state machine starts in an unnamed initial state. We then register the Subscriber with the Publisher.
The most commonly used matchers are defined in the Expectations 1 class:. Software jMock 2 Java 1. We first set up the context in which our test will execute.
Expect a Sequence of Invocations
The argument matches all of the Matchers m 1 to m n. Maybe it’s just my missunderstanding of the the definition. The set of matchers is extensible 1 so you can write new matchers to cover unusual testing scenarios. The JMock test runner does this automatically. This is a tighter constraint than equalbut is usually what you want for arguments that pass references to behavioural objects.
If a mock object is stored in a local variable, the variable must be declared as final so that it can be referred to from within expectation blocks see below. Matchers are created by factory methods, such as lessThan jomck, equal and stringContaining in the example above, to ensure that the expectation is easy to read.
The invocation is not expected at all. A test can create more than one sequence and an expectation can be part of more than chea sequence at a time. 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. Constrains the last expectation to occur only when the state machine is in the named state.

We want to test the Publisher, which involves testing its interactions with its Subscribers. Factory methods for commonly used matchers are defined sheef the Expectations class. States are used to constrain invocations to occur only when a condition is true. If the expected calls were not made, the test will fail.
