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 .

JMock to Scalamock Cheat Sheet

By convention the Mockery is stored in an instance variable named context. To expect a sequence of invocations, write the expectations in order and hceat the inSequence sequence clause to each one. JUnit 3 JUnit 4 Other. A test can create more than one sequence and an expectation can be part of more than once sequence at a time.

In tests I can see using one and in other there is oneOf. Conditions are represented as states of state chwat.

An expectations block can contain any number of expectations. Next we define expectations chear on the mock Subscriber that specify the methods that we expect to be called upon it during the test run. This is useful for ignoring arguments that are not relevant to the scenario being tested.


The invocation is expected at least min times and at most max times. 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 jomck test. The most commonly used matchers are defined in the Expectations 1 class:.

Post as a guest Name. The examples above assume that the mock object is stored in an instance variable. The code below, for example, specifies that the method “doSomething” must be called with one argument of value 1.

In cheat sheet mentioned before there is also example: JUnit 3 JUnit 4 Other. The argument matches all of the Matchers m 1 to m n. We will test that a Publisher sends shet message to a single registered Subscriber.

The most cheaat used matcher is equalwhich specifies that the received argument must be equal to a given value. Matchers can be composed to create a tighter or looser specification. Loose parameter constraints are defined by specifying matchers for each parameter. Stack Overflow works best with JavaScript enabled.

Do all actions a 1 to a n on every invocation. Well this finally make sense: You can give an expectation as many inSequencewhenwill and then clauses as you wish. If a mock object is stored in a local ceat, the variable must be declared as final so that it can be referred to from within expectation blocks see below.


Constrains the last expectation to occur only when the state machine is in the named state. The invocation is not expected at all.

If cheqt specified, the state machine starts in an unnamed initial state. ERRORwith stringContaining “sqrt” ; Loose parameter constraints sheeet defined by specifying matchers for each parameter.

The argument matches one of the Matchers m 1 to m n. The JMock test runner does this automatically. Cheat sheet says that: Allowing or ignoring should be chosen to make the test code clearly express intent.

The jMock jmofk is explored in more depth in other Cookbook recipes 2. The argument is any value. LoganMzz 1, 2 12 Software jMock 2 Java 1. Factory methods for commonly used matchers are defined in the Expectations class. A test can create multiple state machines and each state machine can have multiple states.

A test can contain multiple expectation blocks. We expect the receive method to be called once with a single argument, the message that will be sent.
