Tick IT!
A function which pushes a new task into the queue in order to provide convenient way to wait for completion of micro-tasks. It's quite useful for testing:
import tick from 'tick-it';
class Service {
foo(promise) {
promise.then(data => this.bar(data));
}
bar(data) {
// do stuff
}
}
describe('async module', () => {
let service;
beforeEach(() => {
service = new Service();
});
it('should work', async () => {
const spy = spyOn(service, 'bar');
service.foo(Promise.resolve({ foo: 'bar' }));
await tick();
expect(spy).toHaveBeenCalled();
});
});
