Constructor Detail

MockObject

public MockObject(Class<?> mockedType,
          Object testObject)

Creates a mock of the given type with un-capitalized type name + Mock as name, e.g. myServiceMock. There is no .class literal for generic types. Therefore you need to pass the raw type when mocking generic types. E.g. Mock<List<String>> myMock = new MockObject("myMock", List.class, this); If the mocked type does not correspond to the declared type, a ClassCastException will occur when the mock is used.

Parameters:

mockedType - The mock type that will be proxied, use the raw type when mocking generic types, not null

testObject - The test object, not null

MockObject

public MockObject(String name,
          Class<?> mockedType,
          Object testObject)

Creates a mock of the given type. There is no .class literal for generic types. Therefore you need to pass the raw type when mocking generic types. E.g. Mock<List<String>> myMock = new MockObject("myMock", List.class, this); If the mocked type does not correspond to the declared type, a ClassCastException will occur when the mock is used. If no name is given the un-capitalized type name + Mock is used, e.g. myServiceMock

Parameters:

name - The name of the mock, e.g. the field-name, null for the default

mockedType - The mock type that will be proxied, use the raw type when mocking generic types, not null

testObject - The test object, not null

Method Detail

getCurrentScenario

public static Scenario getCurrentScenario()

getObjectToInject

public T getObjectToInject()

Returns the mock proxy instance. This is the object that must be injected if the field that it holds is annotated with @InjectInto or one of it's equivalents.

Specified by:

getObjectToInject in interface ObjectToInjectHolder<T>

Returns:

The mock proxy instance, not null

getObjectToInjectType

public Type getObjectToInjectType(Field field)

Specified by:

getObjectToInjectType in interface ObjectToInjectHolder<T>

Parameters:

field - The field that declared this mock object, null if there is no field (or not known)

Returns:

The type of the object to inject (i.e. the mocked type), not null.

getMock

public T getMock()

Returns the mock proxy instance. This is the instance that can be used to perform the test. You could for example inject it in the tested object. It will then perform the defined behavior and record all observed method invocations so that assertions can be performed afterwards.

Specified by:

getMock in interface Mock<T>

Returns:

The proxy instance, not null

getMockedType

public Class<?> getMockedType()

Returns:

the type of the mock, not null

returns

public T returns(Object returnValue)

Defines behavior for this mock so that it will return the given value when the invocation following this call matches the observed behavior. E.g.

mock.returns("aValue").method1();

will return "aValue" when method1 is called.

Note that this behavior is executed each time a match is found. So "aValue" will be returned each time method1() is called. If you only want to return the value once, use the onceReturns(java.lang.Object) method.

Specified by:

returns in interface Mock<T>

Parameters:

returnValue - The value to return

Returns:

The proxy instance that will record the method call, not null

raises

public T raises(Throwable exception)

Defines behavior for this mock so that it raises the given exception when the invocation following this call matches the observed behavior. E.g.

mock.raises(new MyException()).method1();

will throw the given exception when method1 is called.

Note that this behavior is executed each time a match is found. So the exception will be raised each time method1() is called. If you only want to raise the exception once, use the onceRaises(java.lang.Throwable) method.

Specified by:

raises in interface Mock<T>

Parameters:

exception - The exception to raise, not null

Returns:

The proxy instance that will record the method call, not null

raises

public T raises(Class<? extends Throwable> exceptionClass)

Defines behavior for this mock so that it raises the given exception when the invocation following this call matches the observed behavior. E.g.

mock.raises(MyException.class).method1();

will throw an instance of the given exception class when method1 is called.

Note that this behavior is executed each time a match is found. So the exception will be raised each time method1() is called. If you only want to raise the exception once, use the onceRaises(java.lang.Throwable) method.

Specified by:

raises in interface Mock<T>

Parameters:

exceptionClass - The type of exception to raise, not null

Returns:

The proxy instance that will record the method call, not null

performs

public T performs(MockBehavior mockBehavior)

Defines behavior for this mock so that will be performed when the invocation following this call matches the observed behavior. E.g.

mock.performs(new MyMockBehavior()).method1();

will execute the given mock behavior when method1 is called.

Note that this behavior is executed each time a match is found. So the behavior will be executed each time method1() is called. If you only want to execute the behavior once, use the oncePerforms(org.unitils.mock.mockbehavior.MockBehavior) method.

Specified by:

performs in interface Mock<T>

Parameters:

mockBehavior - The behavior to perform, not null

Returns:

The proxy instance that will record the method call, not null

onceReturns

public T onceReturns(Object returnValue)

Defines behavior for this mock so that it will return the given value when the invocation following this call matches the observed behavior. E.g.

mock.returns("aValue").method1();

will return "aValue" when method1 is called.

Note that this behavior is executed only once. If method1() is invoked a second time, a different behavior definition will be used (if defined) or a default value will be returned. If you want this definition to be able to be matched multiple times, use the method returns(java.lang.Object) instead.

Specified by:

onceReturns in interface Mock<T>

Parameters:

returnValue - The value to return

Returns:

The proxy instance that will record the method call, not null

onceRaises

public T onceRaises(Throwable exception)

Defines behavior for this mock so that it raises the given exception when the invocation following this call matches the observed behavior. E.g.

mock.raises(new MyException()).method1();

will throw the given exception when method1 is called.

Note that this behavior is executed only once. If method1() is invoked a second time, a different behavior definition will be used (if defined) or a default value will be returned. If you want this definition to be able to be matched multiple times, use the method raises(java.lang.Throwable) instead.

Specified by:

onceRaises in interface Mock<T>

Parameters:

exception - The exception to raise, not null

Returns:

The proxy instance that will record the method call, not null

onceRaises

public T onceRaises(Class<? extends Throwable> exceptionClass)

Defines behavior for this mock so that it raises an instance of the given exception class when the invocation following this call matches the observed behavior. E.g.

mock.raises(new MyException()).method1();

will throw an instance of the given exception class when method1 is called.

Note that this behavior is executed only once. If method1() is invoked a second time, a different behavior definition will be used (if defined) or a default value will be returned. If you want this definition to be able to be matched multiple times, use the method raises(java.lang.Throwable) instead.

Specified by:

onceRaises in interface Mock<T>

Parameters:

exceptionClass - The type of exception to raise, not null

Returns:

The proxy instance that will record the method call, not null

oncePerforms

public T oncePerforms(MockBehavior mockBehavior)

Defines behavior for this mock so that will be performed when the invocation following this call matches the observed behavior. E.g.

mock.performs(new MyMockBehavior()).method1();

will execute the given mock behavior when method1 is called.

Note that this behavior is executed only once. If method1() is invoked a second time, a different behavior definition will be used (if defined) or a default value will be returned. If you want this definition to be able to be matched multiple times, use the method performs(org.unitils.mock.mockbehavior.MockBehavior) instead.

Specified by:

oncePerforms in interface Mock<T>

Parameters:

mockBehavior - The behavior to perform, not null

Returns:

The proxy instance that will record the method call, not null

Specified by:

assertInvokedInSequence in interface Mock<T>

Returns:

The proxy instance that will record the method call, not null

assertNotInvoked

public T assertNotInvoked()
