Unit Testing with Ionic 2 RC0

Short description of the problem:

I'm starting an Ionic 2 project using RC0 and I'm having trouble getting unit tests to work. Almost all the documentation found on the web is for the beta releases that still used gulp. Is there any documentation on how to set it up with the new building system?

I can see that ionic-app-scripts already checks for linter errors, is there any planning to support unit testing?

This is a much needed feature. We have around 700 tests that we used to run with gulp, have debugging, source maps etc and cannot think of not having them for too long.
Having a way to run tests would also make the upgrade to RC0 much easier and safer.

@jgw96: Do you already know if you'll integrate the angular-cli mechanism (ng test) as a task into the ionic-app-scripts to run the tests?

So we could integrate it this way now in the our project and later just switch the task in the package.json.

Yes the plan is to make it as easy as ionic test, which could also be ran as npm run test. To do this we'll have to add a default karma config like how all the other tasks are added. This is on our roadmap to complete soon. Thanks.

Thanks @adamdbradley for your answer. This sounds great to have it the easy way like ionic test.

If you are going to use protractor for the e2e tests, I'd kindly ask to add some upvotes or a comment to the issue on adding mock modules to Angular 2 applications, so that this feature request gets more attention and will hopefully be completed soon. Mocking modules like the http backend will be essential for e2e tests.
Thanks in advance.

Hey guys, I've created a structure to use unit tests on RC.0 release. By now, only works with sidemenu scaffold. Tabs scaffold for example, have others dependencies that I couldn't find easily. So, still problems with some providers mocks :\

Please, see this gist: https://gist.github.com/mfdeveloper/d9349dea78ba34a36adc7ada56ffd0c0
And a discussion here: marcoturi/ionic-boilerplate#1

last release of https://github.com/marcoturi/ionic2-boilerplate has e2e and unit tests working with rc0

@marcoturi That's great! One thing we're trying to do is really reduce any required dependencies. What can we do to add karma, but keep any new dependencies to a minimum? https://github.com/marcoturi/ionic2-boilerplate/blob/master/package.json#L129
