api.getPersonByName('bob').then(person => {
expect(person).toHaveProperty('name', 'Bob');
});
});
it('promises a counted person', () => {
const promise = api.getPersonByName('bob').then(person => {
expect(person).toHaveProperty('name', 'Bob');
});
promise.then(() => {
expect(analytics.gottenPeopleCount).toBe(1);
});
});
it('promises multiple people', () => {
const firstPromise = api.getPersonByName('bob').then(person => {
expect(person).toHaveProperty('name', 'Bob');
});
const secondPromise = api.getPersonByName('alice').then(person => {
expect(person).toHaveProperty('name', 'Alice');
});
return Promise.any([firstPromise, secondPromise]);
});
The following pattern is not warning:
it('promises a person', async () => {

});
});
it('promises a counted person', () => {
let promise = api.getPersonByName('bob').then(person => {
expect(person).toHaveProperty('name', 'Bob');
});
promise = promise.then(() => {

});
return promise;
});
