GivenWhenThenTestFixture

public GivenWhenThenTestFixture(Class<T> aggregateType)

Initializes a new given-when-then style test fixture for the given aggregateType.

Parameters:

aggregateType - The aggregate to initialize the test fixture for

Method Detail

registerRepository

public FixtureConfiguration<T> registerRepository(EventSourcingRepository<T> eventSourcingRepository)

Description copied from interface: FixtureConfiguration

Registers an arbitrary event sourcing repository with the fixture. The repository must be wired with the Event Store of this test fixture.

Should not be used in combination with FixtureConfiguration.registerAggregateFactory(org.axonframework.eventsourcing.AggregateFactory), as that will overwrite any repository previously registered.

Specified by:

registerRepository in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

eventSourcingRepository - The repository to use in the test case

Returns:

the current FixtureConfiguration, for fluent interfacing

registerAggregateFactory

public FixtureConfiguration<T> registerAggregateFactory(AggregateFactory<T> aggregateFactory)

Description copied from interface: FixtureConfiguration

Registers the given aggregateFactory with the fixture. The repository used by the fixture will use the given factory to create new aggregate instances. Defaults to an Aggregate Factory that uses the no-arg constructor to create new instances.

Should not be used in combination with FixtureConfiguration.registerRepository(org.axonframework.eventsourcing.EventSourcingRepository), as that will overwrite any aggregate factory previously registered.

Specified by:

registerAggregateFactory in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

aggregateFactory - The Aggregate Factory to create empty aggregates with

Returns:

the current FixtureConfiguration, for fluent interfacing

registerAnnotatedCommandHandler

public FixtureConfiguration<T> registerAnnotatedCommandHandler(Object annotatedCommandHandler)

Description copied from interface: FixtureConfiguration

Registers an annotatedCommandHandler with this fixture. This will register this command handler with the command bus used in this fixture.

Specified by:

registerAnnotatedCommandHandler in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

annotatedCommandHandler - The command handler to register for this test

Returns:

the current FixtureConfiguration, for fluent interfacing

Description copied from interface: FixtureConfiguration

Registers a commandHandler to handle commands of the given commandType with the command bus used by this fixture.

Specified by:

registerCommandHandler in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

payloadType - The type of command to register the handler for

commandHandler - The handler to register

Returns:

the current FixtureConfiguration, for fluent interfacing

registerCommandHandler

public FixtureConfiguration<T> registerCommandHandler(String commandName,
                                             CommandHandler commandHandler)

Description copied from interface: FixtureConfiguration

Registers a commandHandler to handle commands of the given commandType with the command bus used by this fixture.

Specified by:

registerCommandHandler in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

commandName - The name of the command to register the handler for

commandHandler - The handler to register

Returns:

the current FixtureConfiguration, for fluent interfacing

registerInjectableResource

public FixtureConfiguration<T> registerInjectableResource(Object resource)

Description copied from interface: FixtureConfiguration

Registers a resource that is eligible for injection in @CommandHandler and @EventHandler annotated methods. These resource must be registered before registering any command handler.

Specified by:

registerInjectableResource in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

resource - The resource eligible for injection

Returns:

the current FixtureConfiguration, for fluent interfacing

given

public TestExecutor given(Object... domainEvents)

Description copied from interface: FixtureConfiguration

Configures the given domainEvents as the "given" events. These are the events returned by the event store when an aggregate is loaded.

If an item in the given domainEvents implements Message, the payload and meta data from that message are copied into a newly created Domain Event Message. Otherwise, a Domain Event Message with the item as payload and empty meta data is created.

Specified by:

given in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

domainEvents - the domain events the event store should return

Returns:

a TestExecutor instance that can execute the test with this configuration

given

public TestExecutor given(List<?> domainEvents)

Description copied from interface: FixtureConfiguration

Configures the given domainEvents as the "given" events. These are the events returned by the event store when an aggregate is loaded.

If an item in the list implements Message, the payload and meta data from that message are copied into a newly created Domain Event Message. Otherwise, a Domain Event Message with the item as payload and empty meta data is created.

Specified by:

given in interface FixtureConfiguration<T extends EventSourcedAggregateRoot>

Parameters:

domainEvents - the domain events the event store should return

Returns:

a TestExecutor instance that can execute the test with this configuration

givenCommands

public TestExecutor givenCommands(Object... commands)

Description copied from interface: FixtureConfiguration

Configures the given commands as the command that will provide the "given" events. The commands are executed, and the resulting stored events are captured.

Specified by:

Parameters:

commands - the domain events the event store should return

Returns:

a TestExecutor instance that can execute the test with this configuration

givenCommands

public TestExecutor givenCommands(List<?> commands)

Parameters:

commands - the domain events the event store should return

Returns:

a TestExecutor instance that can execute the test with this configuration
