示例1: describe
describe('Core/Dispatcher', () => {
const actionTypeFactory = new ActionTypeFactory('Dummy');
let dispatcher = new Dispatcher;
beforeEach(() => {
dispatcher = new Dispatcher;
});
describe('#dispatch()', () => {
it('should work successfully', () => {
const actionType = actionTypeFactory.create('dummyAction');
const action = { type: actionType };
expect(() => dispatcher.dispatch(action)).to.not.throw(Error);
});
it('should return promise', () => {
const actionType = actionTypeFactory.create('dummyAction');
const action = { type: actionType };
expect(dispatcher.dispatch(action)).to.be.a('promise');
});
context('when payload is promise', () => {
const actionType = actionTypeFactory.create('dummyAction');
const value = 'value';
context('when payload promise is resolved', () => {
it('should dispatch another action when payload is promise', (done) => {

let callCount = 0;
dispatcher.registerSubscriber(({payload, asyncStatus}) => {

if (callCount === 1) {
expect(payload).to.be.a('promise');
expect(asyncStatus).to.be.undefined;
}
if (callCount === 2) {
