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 cheat sheet mentioned before there is also example: The question is if there is any difference between this keywords or it means equaly the same thing. The set jmick matchers is extensible 1 so you can write new matchers to cover unusual testing scenarios.
jMock – Getting Started
After the code under test has finished our test must verify that the mock Subscriber was called as expected. A Publisher sends messages to zero or more Subscribers. Seet test can contain multiple expectation blocks.
The following clauses constrain invocations to occur within specific states and define how an invocation will change the current state of a state machine. Loose parameter constraints are defined by specifying matchers for sheeet parameter.
jMock 1 Documentation
Most of the time expectations specify literal parameter values that are compared for equality against the actual parameters of invoked methods.
Arrays are treated as a special case: By convention the Mockery is stored in an instance variable named context. As a rule of thumb, use equal for value objects and same for behavioural objects.
Null values are checked beforehand, so it is safe to specify equal null or apply the matcher to a null actual value. Matchers can be composed to create a tighter or looser specification. The most commonly used matchers are defined in the Expectations 1 class:.
More matchers are defined as static methods in the org. Matchers can be combined to tighten or loosen the specification if necessary. JUnit 3 JUnit 4 Other. This is a tighter constraint than equalbut is usually what you want for arguments that pass references to behavioural objects.
JUnit 3 JUnit 4 Other.
The allOf matcher specifies that the actual argument must meet all of the matchers given as arguments. 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. For example, zheet code above would accept any of the following argument values: An expectations block can contain any number of expectations. The invocation is expected at least min times eheet at most max times.
Do all actions a 1 to a n on every invocation. In tests I can see using one and in other there is oneOf. The not matcher specifies that the actual argument must not match a given matcher.
This is used to make tests more explicit and so easier to understand. The Subscriber dheat looks like this: The JMock test runner does this automatically. But the exactly one aka exactly 1. Software jMock 2 Java 1. Constrains the last expectation to occur only when the state machine is in the named state.
The invocation is not expected at all. The result of each factory method must be wrapped by a call to the with method. Matchers are created by factory methods, such as lessThanequal and stringContaining in the example above, to ensure that the expectation is easy to read. We create a Publisher to test. Return a new iterator over elements v 1 to v n on each invocation.
Conditions are represented as states of state machines. Email Required, but never shown. Next we define expectations 1 on the mock Subscriber that specify the methods that we expect to be called upon it during the test run.
Invocations that are expected in a sequence must occur in the order in which they appear in the test code.

Judicious use of the any constraint ensure that your tests are flexible and do not require constant maintenance when tested code changes. If not specified, the state machine starts in an unnamed initial state. Expectations in later blocks are appended to those in earlier blocks.
Composite matchers are themselves matchers and can therefore be further composed.
