Test if a promise is resolved or rejected with Jasmine in Nodejs

Question

I know how to do it in Mocha but want to know how to do it with Jasmine. I tried this

describe('test promise with jasmine', function() {     it('expects a rejected promise', function() {         var promise = getRejectedPromise();          // return expect(promise).toBe('rejected');         return expect(promise.inspect().state).toBe('rejected');     }); }); 

However, the state is always pending and, of course, the test fails. I couldn't find any example online that I could make it work.

Can someone please help me with this?

Thanks.

Answer 1

you can now use expectAsync()

Expecting success:

it('expect result', async () => {    ...    await expectAsync(someAsyncFunction(goodInput)).toBeResolved(expectedResponse) }) 

Expecting failure:

it('expect result', async () => {    ...    await expectAsync(someAsyncFunction(badInput)).toBeRejectedWith(expectedResponse) })
