Example code should contain mock samples

[ezyang]

There appears to be mocking documentation in https://github.com/actions/toolkit/blob/master/docs/github-package.md but the example code that you can use to bootstrap an action should also contain this code, or at the very least, link to this documentation.

note, lots of mocking examples in https://github.com/actions/checkout/tree/v2/__test__

That code you link to has helped me quite a bit. Where I'm struggling is in how to mock THIS library in such a way that I can control stdout. For instance, how do I inject strings into stdout so that I don't have to actually execute something in order to test the code that expects that output?

setup-go has more mocking examples including output. https://github.com/actions/setup-go/blob/master/__tests__/setup-go.test.ts#L62

I'm going to write up a doc with examples soon.
