A convenience type alias for referring to a test store of a given reducer’s domain.
typealias TestStoreOf<R> = TestStore<R.State, R.Action> where R : Reducer, R.State : EquatableInstead of specifying two generics:
let testStore: TestStore<Feature.State, Feature.Action>You can specify a single generic:
let testStore: TestStoreOf<Feature>import ComposableArchitectureThe Composable Architecture (TCA, for short) is a library for building applications in a consistent and understandable way, with composition, testing, and ergonomics in mind. It can be used in SwiftUI, UIKit, and more, and on any Apple platform (iOS, macOS, tvOS, and watchOS).
@preconcurrency @MainActor final class TestStore<State, Action> where State : EquatableA testable runtime for a reducer.
associatedtype StateA type that holds the current state of the reducer.
associatedtype ActionA type that holds all possible actions that cause the State of the reducer to change and/or kick off a side Effect that can communicate with the outside world.
protocol Reducer<State, Action>A protocol that describes how to evolve the current state of an application to the next state, given an action, and describes what Effects should be executed later by the store, if any.
protocol EquatableA type that can be compared for value equality.
@MainActor init(initialState: @autoclosure () -> State, reducer: () -> some Reducer<State, Action>, withDependencies prepareDependencies: (inout DependencyValues) -> Void = { _ in }, fileID: StaticString = #fileID, file filePath: StaticString = #filePath, line: UInt = #line, column: UInt = #column) Creates a test store with an initial state and a reducer powering its runtime.
