An integration test framework for React Native.

// Public: A TestHookStore stores flattened references to UI components in your
// app that you want to interact with as part of your integration tests.
//
// See Tester.js for an example of instantiating a TestHookStore for use with
// a `<Tester />` component.
export default class TestHookStore {
  constructor() {
    this.hooks = {};
  }

  // Internal: Add a new component into the store. If there is an existing
  // component with that identifier, replace it.
  //
  // identifier - String, a unique identifier for this component. To help
  //              separate out hooked components, use dot namespaces e.g.
  //              'MyScene.mycomponent'.
  // component  - Component returned by React `ref` function.
  //
  // Returns undefined.
  add(identifier, component) {
    this.hooks[identifier] = component;
  }

  // Internal: Remove a component from the store.
  //
  // Returns undefined.
  remove(identifier) {
    delete this.hooks[identifier];
  }

  // Internal: Fetch a component from the store.
  //
  // Returns the component corresponding to the provided identifier, or
  // undefined if it has not been added.
  get(identifier) {
    return this.hooks[identifier];
  }
