Struct DeciderTestSpecification

pub struct DeciderTestSpecification<'a, Command, State, Event, Error>
where
    Event: PartialEq + Debug,
    Error: PartialEq + Debug,
{ /* private fields */ }

A test specification DSL for deciders that supports the given-when-then format. The DSL is used to specify the events that have already occurred (GIVEN), the command that is being executed (WHEN), and the expected events (THEN) that should be generated.

Implementations

impl<'a, Command, State, Event, Error> DeciderTestSpecification<'a, Command, State, Event, Error>

where Event: PartialEq + Debug, State: PartialEq + Debug, Error: PartialEq + Debug,

pub fn for_decider( self, decider: Decider<'a, Command, State, Event, Error>, ) -> Self

Specify the decider you want to test

pub fn given(self, events: Vec<Event>) -> Self

Given preconditions / previous events

pub fn given_state(self, state: Option<State>) -> Self

Given preconditions / previous state

pub fn when(self, command: Command) -> Self

When action/command

pub fn then(self, expected_events: Vec<Event>)

Then expect result / new events

pub fn then_state(self, expected_state: State)

Then expect result / new events

pub fn then_error(self, expected_error: Error)

Then expect error result / these are not events

Trait Implementations

impl<Command, State, Event, Error> Default for DeciderTestSpecification<'_, Command, State, Event, Error>

where Event: PartialEq + Debug, Error: PartialEq + Debug,

fn default() -> Self

Returns the “default value” for a type.
