unexpected-promise v1.3.0

unexpected-promise

Plugin for the Unexpected assertion lib adding Promise support. Requires Unexpected 7 or above.

var expect = require('unexpected').installPlugin(require('unexpected-promise'));

it('should DTRT', function () {
    return expect(myPromise, 'to be resolved with', 'foobar');
});

it('should fail', function () {
    return expect(myPromise, 'to be rejected with', new Error('argh'));
});

Alternatively you can use the when resolved and when rejected assertions to replace the subject with the resolved value or rejection reason, then apply another assertion to it:

it('should DTRT', function () {
    return expect(myPromise, 'when resolved', 'to equal', 'foobar');
});

it('should fail', function () {
    return expect(myPromise, 'when rejected', 'to have property', 'message', 'argh');
});
