docs: README info about running tests

[juristr]

The current README is out of date as it still refers to running tests with node. Instead the package.json scripts have been modified to use Bazel instead.

@juristr, thanks for this.

Can you please make the changes here instead https://github.com/angular/angular-cli/blob/master/scripts/templates/readme.ejs and run yarn admin templates

[juristr]

@alan-agius4 oh I see. Will do later 👍

[cexbrayat]

@juristr 👍 Awesome!

I think it would be great to also showcase how you can run only some of the tests, as the full build takes forever.
I'm using yarn bazel test //packages/angular_devkit/build_angular:build_angular_browser_test for example but maybe someone has an even better command than this? Is there a way to have even more granularity? When you want to make a small contribution, and run just one spec, it would be great to find how to do it in the README.

[juristr]

@cexbrayat agree, unfortunately I don't either. Didn't look into it. I just had to run the tests myself and found the outdated readme, which is why I went and submitted this PR :)

Maybe @alan-agius4 knows 🙂

@alan-agius4 I'm gonna fix this PR in the coming days

You can use the standard jasmine methods fit and fdescribe.

[cexbrayat]

@alan-agius4 Might be worth adding to the README, but Bazel will still download and compile everything no? yarn bazel test //packages/angular_devkit/build_angular:build_angular_browser_test might be worth mentionning as it "just" compile the package you try to test?

[alan-agius4]

Closing as this should be already fixed on master.
