shouldjsshould-promised
There some helpers for asserting promises.
.Promise
Assert given object is promise
.fulfilled
Assert given promise will be fulfilled. It will return promise.
it('should be allow to check if promise fulfilled', function() {
return promised(10).should.be.fulfilled;
});
.fulfilledWith
Assert given promise will be fulfilled with an expected value. It will return promise.
it('should be allow to check if promise fulfilledWith an expected value', function() {
return promised(10).should.be.fulfilledWith(10);
});
.rejected
Assert given promise will be rejected. It will return promise.
it('should be allow to check if promise rejected', function() {
return promiseFail().should.be.rejected;
});
.rejectedWith
Assert given promise will be rejected with matched Error. Arguments are the same as Assertion#throw.
.finally or .eventually
This method begin assertions for promises, all next .chain calls will be shortcuts for .thenable calls on promise.
So you can do like this
promised('abc').should.finally.be.exactly('abc')
.and.be.a.String;
//or combine with any of Promise methods as any assertion will return Promise itself
Promise.all([
promised(10).should.finally.be.a.Number,
promised('abc').should.finally.be.a.String
])
Before .finally
Everything you did before .finally saved into new assertion (but that is not quite usefull as object will be promise).
Main idea is to save .not and .any.
