Interface ResultValidator<T>

Type Parameters:

T - The type of Aggregate under test

All Known Implementing Classes:

ResultValidatorImpl

public interface ResultValidator<T>

Interface describing the operations available on the "validate result" (a.k.a. "then") stage of the test execution. The underlying fixture expects a test to have been executed successfully using a TestExecutor.

There are several things to validate:

• the published events,
• the stored events, and
• the command handler's execution result, which is one of
  • a regular return value,
  • a void return value, or
  • an exception.

Method Detail

expectEvents

ResultValidator<T> expectEvents(Object... expectedEvents)

Expect the given set of events to have been published.

All events are compared for equality using a shallow equals comparison on all the fields of the events. This means that all assigned values on the events' fields should have a proper equals implementation.

Note that the event identifier is ignored in the comparison.

Parameters:

expectedEvents - The expected events, in the exact order they are expected to be dispatched and stored.

Returns:

the current ResultValidator, for fluent interfacing

expectEvents

ResultValidator<T> expectEvents(EventMessage<?>... expectedEvents)

Expect the given set of events to have been published.

All events are compared for equality using a shallow equals comparison on all the fields of the events. This means that all assigned values on the events' fields should have a proper equals implementation.
Additionally the metadata will be compared too.

Note that the event identifier is ignored in the comparison.

Parameters:

expectedEvents - The expected events, in the exact order they are expected to be dispatched and stored.

Returns:

the current ResultValidator, for fluent interfacing

expectNoEvents

default ResultValidator<T> expectNoEvents()

Expect no events to have been published from the command.

Returns:

the current ResultValidator, for fluent interfacing

expectEventsMatching

ResultValidator<T> expectEventsMatching(org.hamcrest.Matcher<? extends List<? super EventMessage<?>>> matcher)

Expect the published events to match the given matcher.

Note: if no events were published, the matcher receives an empty List.

Parameters:

matcher - The matcher to match with the actually published events

Returns:

the current ResultValidator, for fluent interfacing

expectResultMessagePayload

ResultValidator<T> expectResultMessagePayload(Object expectedPayload)

Expect the command handler to return the given expectedPayload after execution. The actual and expected values are compared using their equals methods.

Parameters:

expectedPayload - The expected result message payload of the command execution

Returns:

the current ResultValidator, for fluent interfacing

expectResultMessagePayloadMatching

ResultValidator<T> expectResultMessagePayloadMatching(org.hamcrest.Matcher<?> matcher)

Expect the command handler to return a payload that matches the given matcher after execution.

Parameters:

matcher - The matcher to verify the actual return value against

Returns:

the current ResultValidator, for fluent interfacing

expectResultMessage

ResultValidator<T> expectResultMessage(CommandResultMessage<?> expectedResultMessage)

Expect the command handler to return the given expectedResultMessage after execution. The actual and expected values are compared using their equals methods.

Comparison is done on message payload and meta data.

Parameters:

expectedResultMessage - The expected result message of the command execution

Returns:

the current ResultValidator, for fluent interfacing

expectResultMessageMatching

ResultValidator<T> expectResultMessageMatching(org.hamcrest.Matcher<? super CommandResultMessage<?>> matcher)

Expect the command handler to return a value that matches the given matcher after execution.

Parameters:

matcher - The matcher to verify the actual result message against

Returns:

the current ResultValidator, for fluent interfacing

Expect an exception message to occur during command handler execution that matches with the given matcher.

Parameters:

matcher - The matcher to validate the actual exception message

Returns:

the current ResultValidator, for fluent interfacing

expectExceptionMessage

ResultValidator<T> expectExceptionMessage(String exceptionMessage)

Expect the given exceptionMessage to occur during command handler execution. The actual exception message should be exactly the same as exceptionMessage.

Returns:

the current ResultValidator, for fluent interfacing

expectException

ResultValidator<T> expectException(Class<? extends Throwable> expectedException)

Expect the given expectedException to occur during command handler execution. The actual exception should be exactly of that type, subclasses are not accepted.

Returns:

the current ResultValidator, for fluent interfacing

expectException

ResultValidator<T> expectException(org.hamcrest.Matcher<?> matcher)

Provides access the the state of the Aggregate as it was stored in the repository, allowing for validation of the state of the aggregate, as it was left in the repository.

Note that validating state on Event Sourced Aggregate is highly discouraged. Event Sourced aggregates should measure behavior exclusively by measuring emitted events.

Returns:

the current ResultValidator, for fluent interfacing

Throws:

IllegalStateException - when an error in Command execution caused the Unit of Work to be rolled back.
