/**
|
|
* Helper for testing action with expected mutations inspired in
|
|
* https://vuex.vuejs.org/en/testing.html
|
|
*
|
|
* @param {(Function|Object)} action to be tested, or object of named parameters
|
|
* @param {Object} payload will be provided to the action
|
|
* @param {Object} state will be provided to the action
|
|
* @param {Array} [expectedMutations=[]] mutations expected to be committed
|
|
* @param {Array} [expectedActions=[]] actions expected to be dispatched
|
|
* @param {Function} [done=noop] to be executed after the tests
|
|
* @return {Promise}
|
|
*
|
|
* @example
|
|
* testAction(
|
|
* actions.actionName, // action
|
|
* { }, // mocked payload
|
|
* state, //state
|
|
* // expected mutations
|
|
* [
|
|
* { type: types.MUTATION}
|
|
* { type: types.MUTATION_1, payload: expect.any(Number)}
|
|
* ],
|
|
* // expected actions
|
|
* [
|
|
* { type: 'actionName', payload: {param: 'foobar'}},
|
|
* { type: 'actionName1'}
|
|
* ]
|
|
* done,
|
|
* );
|
|
*
|
|
* @example
|
|
* testAction(
|
|
* actions.actionName, // action
|
|
* { }, // mocked payload
|
|
* state, //state
|
|
* [ { type: types.MUTATION} ], // expected mutations
|
|
* [], // expected actions
|
|
* ).then(done)
|
|
* .catch(done.fail);
|
|
*
|
|
* @example
|
|
* await testAction({
|
|
* action: actions.actionName,
|
|
* payload: { deleteListId: 1 },
|
|
* state: { lists: [1, 2, 3] },
|
|
* expectedMutations: [ { type: types.MUTATION} ],
|
|
* expectedActions: [],
|
|
* })
