You can coikbook an expectation as many inSequencewhenwill and then clauses as you wish. The examples above assume that the mock object is stored in an instance variable.

The invocation is expected at least min times and at most max times. Allowing or ignoring should be chosen to coobkook the test code clearly express intent.

jMock – jMock 2 Cheat Sheet

A Mockery represents the context of the object under test: Expectations can be interspersed with calls to the code under test. Changes the state of state-machine to the named state when the invocation occurs. The following clauses constrain invocations to occur within specific states and define how an invocation will change the current state of a state machine.

The type argument is required to force Java to type-check the argument at compile time. Constants have the added benefit of making the test easier to understand than they would be if unnamed, literal values were used.

A test can contain multiple expectation blocks.

A test can create more than one sequence and an expectation can be mmock of more than once sequence at a time. Invocations that are expected in a sequence must occur in the order in which they appear in the test code.

The intial state is optional. Software jMock 2 Java 1. For example, the test above can be rewritten as follows to more clearly express when the cache loads an object will be loaded and when it returns a cached copy:.

Expectations in later blocks are appended to those in earlier blocks. Specifying Expectations Expectations are defined within a “Double-Brace Block” that defines the expectations in the context of the the test’s Mockery identified as context in the examples jmockk. Constrains the last expectation to occur only when the state machine is in the named state.

If a mock object is stored in a local variable, the variable must be declared as final so that it can be referred to from within expectation blocks see below.

The argument matches one of the Matchers m 1 to m n. You can give an expectation as many inSequence 2when 3will and then 4 clauses as you wish. Because the expectations are defined within an anonymous inner class, any mock objects or other values that are stored in local variables and referenced from within the expectations block must be final. Expectations do not have to be defined in the body of the test method.

The JUnit 3 and JUnit 4 integration layers automatically assert that all expectations have been satisfied. JUnit 3 JUnit 4 Other. The argument is not null. The invocation is not expected at all.

Tests written with JUnit 4 do j,ock 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.

An expectations block can contain any number of expectations. Expectations are defined within a “Double-Brace Block” that defines the expectations in the context of the the test’s Mockery identified as context in the examples below.

An invocation can be constrained to occur during a state of one more more state machines. Do all actions a 1 to a n cokbook every invocation. By convention the Mockery is stored in an instance variable named context.

The invocation is expected exactly n times. The same as allowing. The most commonly used matchers are defined in the Expectations 1 class:. A test can contain multiple expectation blocks. States are used to constrain invocations to occur only when a condition is true. A test can create multiple state machines and each state machine can have multiple states. To expect a sequence of invocations, write the expectations in order and add the inSequence sequence clause to each one. It is often more convenient to store mock objects in instance variables and define constants for the values used in the test, as the examples above do.

In outline, a jMock 2 test looks like the following:.
