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 .

As a rule of thumb, use equal for value objects and same for behavioural objects. After the code under test has finished our test must verify that the mock Subscriber was called as expected. A test can create multiple state machines and each state machine can have multiple states.
jMock – Matchers
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.
jMock – Cookbook
Sueet tests I can see using one and in other there is oneOf. The following code specifies that method “doSomething” will be called with one argument hmock refers to the same object as expected. JUnit 3 JUnit 4 Other. The argument matches one of the Matchers m 1 to m n.
An overloaded version of the equal constraint specifies floating point values as equal to another value with some margin of error to account for rounding error. The argument is null.
The equalTo constraint uses the equals method of the expected value to compare the expected and actual values for equality. A test can create more than one sequence and an expectation can be jmlck of more than once sequence at a time. You can give an expectation as many inSequencewhenwill and then clauses as you wish. Null values are checked beforehand, so it is safe to specify equal null or apply the matcher to a null actual value.
The argument is not null. Matchers can be combined to tighten or loosen the specification if necessary. The allOf matcher specifies that the actual argument must meet all of the matchers given as arguments.
The invocation is expected exactly n times. Matchers can be composed to create a tighter or looser specification. Factory methods for commonly used matchers are defined in the Expectations class. Most of the time expectations specify literal shheet values that are compared for equality against the actual parameters of invoked methods.
The not matcher specifies that the actual argument must not match a given matcher. A test can contain multiple expectation blocks.

Sign up using Email and Password. 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 with parameters 2 and 2. Matchers are created by factory methods, such as lessThanequal and stringContaining in the example above, to ensure that the expectation is easy to read.
But the exactly one aka exactly 1. ERRORwith stringContaining “sqrt” ; Loose parameter constraints are defined by specifying matchers for each parameter.
We want to test the Publisher, which involves testing its interactions with its Subscribers. We then register the Subscriber with the Publisher. In cheat sheet mentioned before there cbeat also example: The result of each factory method must be wrapped by a call to the with method. Expectations sheeet be interspersed with calls to the code under test. More matchers are defined as static methods in the org.
