Constructor Detail

SagaTestFixture

public SagaTestFixture(Class<T> sagaType)

Creates an instance of the AnnotatedSagaTestFixture to test sagas of the given sagaType.

Parameters:

sagaType - The type of saga under test

Method Detail

handleInSaga

protected void handleInSaga(EventMessage<?> event)

Handles the given event in the scope of a Unit of Work. If handling the event results in an exception the exception will be wrapped in a FixtureExecutionException.

Parameters:

event - The event message to handle

handleDeadline

protected void handleDeadline(ScopeDescriptor sagaDescriptor,
                              DeadlineMessage<?> deadlineMessage)
                       throws Exception

Handles the given deadlineMessage in the saga described by the given sagaDescriptor. Deadline message is handled in the scope of a UnitOfWork. If handling the deadline results in an exception, the exception will be wrapped in a FixtureExecutionException.

Parameters:

sagaDescriptor - A ScopeDescriptor describing the saga under test

deadlineMessage - The DeadlineMessage to be handled

Throws:

Exception

ensureSagaResourcesInitialized

protected void ensureSagaResourcesInitialized()

Initializes the saga resources if it hasn't already done so. If once initialized, this method does nothing.

withTransienceCheckDisabled

public FixtureConfiguration withTransienceCheckDisabled()

Description copied from interface: FixtureConfiguration

Disables the check that injected resources are stored in fields that are marked 'transient'.

By default, Saga fixtures check for the transient modifier on fields that hold injected resources. These resources are generally not means to be serialized as part of the Saga.

When the transience check reports false positives, this method allows this check to be skipped.

Specified by:

withTransienceCheckDisabled in interface FixtureConfiguration

Returns:

this instance for fluent interfacing.

whenTimeElapses

public FixtureExecutionResult whenTimeElapses(Duration elapsedTime)

Description copied from interface: WhenState

Mimic an elapsed time with no relevant activity for the Saga. If any Events are scheduled to be published within this time frame, they are published. All activity by the Saga on the CommandBus and EventBus (meaning that scheduled events are excluded) is recorded.

Note that if you inject resources using FixtureConfiguration.registerResource(Object), you may need to reset them yourself if they are manipulated by the Saga in the "given" stage of the test.

Specified by:

whenTimeElapses in interface WhenState

Parameters:

elapsedTime - The amount of time to elapse

Returns:

an object allowing you to verify the test results

whenTimeAdvancesTo

public FixtureExecutionResult whenTimeAdvancesTo(Instant newDateTime)

Description copied from interface: WhenState

Mimic an elapsed time with no relevant activity for the Saga. If any Events are scheduled to be published within this time frame, they are published. All activity by the Saga on the CommandBus and EventBus (meaning that scheduled events are excluded) is recorded.

Note that if you inject resources using FixtureConfiguration.registerResource(Object), you may need to reset them yourself if they are manipulated by the Saga in the "given" stage of the test.

Specified by:

whenTimeAdvancesTo in interface WhenState

Parameters:

newDateTime - The time to advance the clock to

Returns:

an object allowing you to verify the test results

registerResource

public void registerResource(Object resource)

Description copied from interface: FixtureConfiguration

Registers the given resource. When a Saga is created, all resources are injected on that instance before any Events are passed onto it.

Note that a CommandBus, EventBus and EventScheduler are already registered as resources, and need not be registered again.

Also note that you might need to reset the resources manually if you want to isolate behavior during the "when" stage of the test.

Specified by:

registerResource in interface FixtureConfiguration

Parameters:

resource - the resource to register.

registerParameterResolverFactory

public FixtureConfiguration registerParameterResolverFactory(ParameterResolverFactory parameterResolverFactory)

Description copied from interface: FixtureConfiguration

Registers a ParameterResolverFactory within this fixture. The given parameterResolverFactory will be added to the other parameter resolver factories introduced through ClasspathParameterResolverFactory.forClass(Class) and the SimpleResourceParameterResolverFactory adding the registered resources (with FixtureConfiguration.registerResource(Object). The type of the saga under test is used as input for the ClasspathParameterResolverFactory#forClass(Class) operation.

Specified by:

registerParameterResolverFactory in interface FixtureConfiguration

Parameters:

parameterResolverFactory - the ParameterResolver to register within this fixture

Returns:

the current FixtureConfiguration, for fluent interfacing

The gateway will dispatch commands on the Command Bus contained in this Fixture, so that you can validate commands using FixtureExecutionResult.expectDispatchedCommands(Object...) and FixtureExecutionResult.expectDispatchedCommandsMatching(org.hamcrest.Matcher).

Note that you need to use FixtureConfiguration.setCallbackBehavior(org.axonframework.test.utils.CallbackBehavior) to defined the behavior of commands when expecting return values. Alternatively, you can use FixtureConfiguration.registerCommandGateway(Class, Object) to define behavior using a stub implementation.

Specified by:

registerCommandGateway in interface FixtureConfiguration

Type Parameters:

I - The gateway type

Parameters:

gatewayInterface - The interface describing the gateway

Returns:

The current FixtureConfiguration, for fluent interfacing.

registerStartRecordingCallback

public FixtureConfiguration registerStartRecordingCallback(Runnable onStartRecordingCallback)

Description copied from interface: FixtureConfiguration

Registers a callback to be invoked when the fixture execution starts recording. This happens right before invocation of the 'when' step (stimulus) of the fixture.

Use this to manage Saga dependencies which are not an Axon first class citizen, but do require monitoring of their interactions. For example, register the callback to set a mock in recording mode.

Specified by:

Returns:

the current FixtureConfiguration, for fluent interfacing

suppressExceptionInGivenPhase

public FixtureConfiguration suppressExceptionInGivenPhase(boolean suppress)

Description copied from interface: FixtureConfiguration

Note that setting this to true means the registered ListenerInvocationErrorHandler is not invoked during exception in the given-phase. Defaults to suppressing during given-phase exceptions.

Specified by:

suppressExceptionInGivenPhase in interface FixtureConfiguration

Parameters:

suppress - A boolean describing whether the fixture should suppress failures during the given-phase.

Returns:

The current fixture, for fluent interfacing.

registerResourceInjector

public FixtureConfiguration registerResourceInjector(ResourceInjector resourceInjector)

Description copied from interface: FixtureConfiguration

Registers a ResourceInjector within this fixture. This approach can be used if a custom ResourceInjector has been built for a project which the user wants to take into account when testing it's sagas.

The provided resourceInjector will be paired with the fixture's default ResourceInjector to keep support for the FixtureConfiguration.registerResource(Object) and FixtureConfiguration.withTransienceCheckDisabled() methods. Note that first the default injector is called, and after that the given resourceInjector. This approach ensures the fixture's correct workings for default provided resources, like the EventBus and CommandBus}, whilst allowing the capability to append and/or override with the given resourceInjector.

Care should be taken if the custom resourceInjector overrides default resources like the EventBus and CommandBus, as the fixture uses specialized versions of the default sources to support all testing functionality.

Specified by:

registerResourceInjector in interface FixtureConfiguration

Parameters:

resourceInjector - the ResourceInjector to register within this fixture

Returns:

the current FixtureConfiguration, for fluent interfacing

getEventBus

public EventBus getEventBus()

Specified by:

getEventBus in interface FixtureConfiguration

Returns:

the event bus used by this fixture

getCommandBus

public RecordingCommandBus getCommandBus()

Description copied from interface: FixtureConfiguration

Returns the command bus used by this fixture. The command bus is provided for wiring purposes only, for example to support composite commands (a single command that causes the execution of one or more others).

Specified by:
