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 .

The argument is not null. The JMock test runner does this automatically. The invocation is expected at least min times and at most max times.

Finally we create a message object to publish. Sign up using Email and Password.

jMock – Cookbook

Composite matchers are themselves matchers and can therefore be further composed. An invocation can be constrained to occur during a state of one more more state machines.

Software jMock 2 Java 1. The Subscriber interface looks like this: Constrains the last expectation to occur only when the state machine jomck in the named state. A test can contain multiple expectation blocks. The argument is null. More matchers are defined as static methods in the org.

The argument matches one cjeat the Matchers m 1 to m n. Software jMock 2 Java 1. By convention the Mockery is stored in an instance variable named context.

Expect a Sequence of Invocations

The code below, for example, specifies that the method “doSomething” must be called with one argument of value 1. Maybe it’s just my missunderstanding of the the definition. Invocations that are expected in a sequence must occur in the order in which chewt appear in the test code.


The following code specifies that the method “doSomething” must be called with a string that either contains the cbeat “hello” or the text “howdy”.

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.

jMock – jMock 1 Documentation

The examples above assume mmock the mock object is stored chwat an instance variable. The most commonly used matchers are defined in the Expectations 1 class:.

Loose parameter constraints are defined by specifying matchers for each parameter. The following code specifies that the method “doSomething” will be called with one argument of value 1 plus or minus 0.

Is any difference in using one or oneOf in JMock? The following code specifies that method “doSomething” must be called with two Strings, the first must be null and the second must not be null. An expectations block can contain any number of expectations.

JMock to Scalamock Cheat Sheet

Expectations in later blocks are appended to those in earlier blocks. We want to test the Publisher, which involves testing its interactions with its Subscribers. The stringContaining matcher is especially useful for testing string contents but isolating tests from the exact details of punctuation and formatting.

To expect a sequence of invocations, write the expectations in order and add the inSequence sequence clause to each one. The MockObjectTestCase does this automatically. ceat

Matchers can be combined to tighten or loosen the specification if necessary. Tests written with JUnit 4 do not need to extend a specific base class but must specify that they use jMock with the RunWith attribute, create a JUnit4Mockery that reports expectation failures as JUnit 4 test failures, and store the Mockery in an instance variable. The allOf matcher specifies that the actual argument must meet all of the matchers given as arguments. In cheat sheet mentioned before there is also example: If you need these, statically import thse Matchers into your test code:.

The following code specifies that method “doSomething” will be called with one argument that refers to the same object as expected. Null values are checked beforehand, so it is safe to specify equal null or apply the matcher to a null actual value. Matchers Most of the time expectations specify literal parameter values that are compared for equality against the actual parameters of invoked methods.

Sign up using Facebook. The not matcher specifies that the actual argument must not match a given matcher. This is a JUnit 3 test case but apart from the test case class the code will be the same when using any test framework for which jMock 2 does not have an integration layer. States are used to constrain invocations to occur only when a condition is true.
