Cannot use Mocha to write angular2 tests #5395
Description
If I use Mocha as a testing framework I'm getting the error message:
/Projects/firebase-pipes/node_modules/angular2/typings/jasmine/jasmine.d.ts(13,18): error TS2300: Duplicate identifier 'it'.
/Projects/firebase-pipes/node_modules/angular2/typings/jasmine/jasmine.d.ts(14,18): error TS2300: Duplicate identifier 'it'.

Is it necessary to propagate Angular with Jasmine typings?

+1, it would be nice to be able to choose between mocha and jasmine :)

We are running Angular 1 and Angular 2 at same time, but we can not do testing at same time.
We started Angular 1 with Jasmine1 testing, and now Angular 2 has built in with Jasmine 2 testing right?
It seems have same typing issue.

@robwormald Any idea how we could move forward without having to fiddle with typings files manually? Or is this resolved by a48 or going to be with a49?
dimitrikochnev commentedon Dec 8, 2015
@dsebastien Can you confirm that mocha plays nicely with angular 2 (I switched to jasmine)? Testing library wraps jasmine methods and in the angularconnect session @juliemr said that currently it doesn't support mocha and other testing frameworks.
juliemr commentedon Dec 8, 2015
That's correct, currently, only Jasmine 2 is fully supported. I'll be working on making this more generic once testing works great with Jasmine 2.
dsebastien commentedon Dec 8, 2015
No I can't, I was just about to try it out. Good to know that it does not work, thanks for the info! ;-)

I'm sure @juliemr will let us know when this is officially supported, but in the meantime, I've found two ways to make it work pretty well -- writeup here: http://www.codeitall.com/?p=144

In beta.2, this issue looks solved to me.

Typings do appear fixed, but the tests still fail under mocha -- i guess that's expected :)

@juliemr Do you have any plans to enable to use Mocha or other testing frameworks with "angular2/testing" ?
I'll be happy if that module will separate to "angular2/testing/common" and "angualr2/testing/jasmine"

This should be fairly easy to create separate adapters - basically one would need to duplicate the logic in https://github.com/angular/angular/blob/master/modules/%40angular/core/testing/testing.ts but for the specific platform one chooses. The logic is thin, so this is a pretty accessible task IMO.
juliemr commentedon Jul 1, 2016
This is now possible in RC4.
