Plugin for the Unexpected assertion lib adding Promise support. Requires Unexpected 7 or above.
NOTE: THIS MODULE SHOULD BE CONSIDERED DEPRECATED AS UNEXPECTED 8.5.0+ HAS THE FEATURES BUILT-IN!
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');
