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 define looser constraints, specify all arguments as matchers within with clauses:. Sign up using Email and Password. We want to test the Publisher, which involves testing its hmock with its Subscribers.

The invocation is expected at least min times and at most max times.

Tests written with JUnit 3 can extend Jmok, in which case they don’t need to explictly create or refer to the context. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of shfet website is subject to these policies. Expectations in later blocks are appended to those in earlier blocks. Sign up or log in Sign up using Google. The not matcher specifies that the actual argument must not match a given matcher.

Well this finally make sense: The examples above assume that the mock object is stored in an instance variable. Sometimes, however, you will need to define looser constraints over parameter values shert clearly express the intent of the test or to ignore parameters or parts of parameters that are not relevant to the behaviour being tested. Constrains the last expectation to occur only when the state machine is in the named state.

More matchers are defined as static factory methods of the Hamcrest Matchers class 2which can be statically imported at the top of the test code.

jMock – Cookbook

Stack Overflow works best with JavaScript enabled. Software jMock 2 Java 1. A Publisher sends messages to zero or more Subscribers.

The allOf matcher specifies that the actual argument must meet all of the matchers given as arguments. Judicious use of the any constraint ensure that your tests are flexible and do not require constant maintenance when tested code changes.

Factory methods for commonly used matchers are defined in the Expectations class. 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.

Take a look at source code of AbstractExpectations. The code below, for example, specifies that the method “doSomething” must be called with one argument of value 1. A test can create multiple state machines and each state machine can have multiple states.

The jMock Cookbook

The following code specifies that the method “doSomething” must be called with an argument that is not equal to 1. If you need these, statically import thse Matchers into your test code:.

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. Conditions are represented as states of state machines. If the expected calls were not made, the test will fail. The type argument is required to force Java to type-check the argument at compile time. 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.

If not specified, the state machine starts in an unnamed initial state. The following code specifies that method “doSomething” must be called with an argument that is a string containing the text “hello”.

The argument matches one of the Matchers m 1 to m n. The most commonly used matchers are defined in the Expectations 1 class:. The argument is any value. By convention the Mockery is stored in an instance variable named context. An expectation that uses parameter matchers must use the “with” method to wrap every parameter, whether a matcher function or a literal value.

Return a new iterator over elements v 1 to v n on each invocation. But the exactly one aka exactly 1. Jmoc invocation is not expected at all. Is any difference in using one or oneOf in JMock?

jMock – Getting Started

Wheet Required, but never shown. Matchers are created by factory methods, such as lessThanequal and stringContaining in the example above, to ensure that the expectation is easy to read. Do all actions a 1 to a n on every invocation. JUnit 3 JUnit 4 Other. The following code specifies that the method “doSomething” must be called with a string that either contains the text “hello” or the text “howdy”.

More matchers are defined as static methods in the org.
