AggregateExpecter

interface AggregateExpecter<S : Any, AE : AggregateExpecter<S, AE>>

Defines the interface for aggregate expectation testing in the WOW framework.

This interface provides methods to assert various aspects of aggregate behavior after command execution, including state validation, event stream verification, and error checking. It supports fluent API chaining for building comprehensive test assertions.

Parameters

S

the type of the aggregate state

AE

the self-referential type for fluent chaining (typically the implementing class)

Inheritors

Functions

abstract fun expect(expected: ExpectedResult<S>.() -> Unit): AE

Applies custom expectations to the test result.

open fun expectError(): AE

Expects that an error occurred during command execution.

open fun <E : Throwable> expectError(expected: Consumer<E>): AE
