Struct ViewTestSpecification

Source 
pub struct ViewTestSpecification<'a, State, Event>
where
    State: PartialEq + Debug,
{ /* private fields */ }
Expand description

A test specification DSL for views that supports the `given-then`` format. The DSL is used to specify the events that have already occurred (GIVEN), and the expected view state (THEN) that should be generated based on these events.

Implementations§

Source§

impl<'a, State, Event> ViewTestSpecification<'a, State, Event>
where State: PartialEq + Debug,

Source

pub fn for_view(self, view: View<'a, State, Event>) -> Self

Specify the view you want to test

Source

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

Given preconditions / events

Source

pub fn then(self, expected_state: State)

Then expect evolving new state of the view
