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 .

To test interactions between the Publisher and the Subscriber we will use a mock Subscriber object. The invocation is expected at least min times and at most max times.
Well this finally make sense: 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. A test can create more than one sequence and an expectation can be part of more than once sequence at hceat time.
jMock – Getting Started
In tests I can see using one and in other there is oneOf. 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. The most commonly used matchers are defined in the Expectations 1 class:. Take a look at source code of AbstractExpectations.

A test can create multiple state machines and each state machine can have multiple states. The invocation is not expected at all.
jMock 2 Cheat Sheet
You can give an expectation as many inSequencewhenwill and then clauses as you wish. By convention the Mockery is stored in an instance variable named context. In cheat sheet mentioned before there is also example: We want to test the Publisher, which involves testing its interactions with its Subscribers.
The stringContaining matcher specifies that the expected argument must be a string that contains the given substring. The JUnit 3 and JUnit 4 integration layers automatically assert that all expectations have been satisfied. This is useful for ignoring arguments that are not relevant to the scenario being tested. Return a new iterator over elements v 1 to v n on each invocation. 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.
The argument is any value.
This is used to make tests more explicit and so easier to understand.

We create a Publisher to test. A test can contain multiple expectation blocks.
Is any difference in using one or oneOf in JMock? But the exactly one aka exactly 1. Finally we create a message sheef to publish. A Mockery represents the context of the object under test: We create a mock Subscriber that should receive the message. Maybe it’s just my missunderstanding of jjock the definition. Factory methods for commonly used matchers are defined in the Expectations class. Matchers can be composed to create a tighter wheet looser specification. The same matcher sneet that the actual value of the argument must be the same object as the expected value.
The stringContaining matcher is especially useful for testing string contents but isolating tests from the exact details of punctuation and formatting. After the code under test has finished our test must verify that the mock Subscriber was called as expected.

The allOf matcher specifies that the actual argument must meet all of the matchers given as arguments. A Mockery creates mock objects and checks expectations that are set upon those mock objects. The type argument is required to force Java to type-check the argument at compile time. The set of cyeat is extensible 1 so you can write new matchers to cover unusual testing scenarios.
Do all actions a 1 to a n on every invocation. Except for the invocation count and the mock object, all clauses are optional. You don’t have to explicitly verify the mock objects in your tests. JUnit 3 JUnit 4 Other.
Expect a Sequence of Invocations
The equalTo constraint uses the equals method of the expected value to compare the expected and actual values for equality. Expectations in later blocks are appended to those in earlier blocks. To define looser constraints, specify all arguments as matchers within with clauses:.
More matchers are defined as static factory methods of the Hamcrest Matchers class 2which can be statically imported at the top of the test jmoxk. If not specified, the state machine starts in an unnamed initial state.
