docs: Testing-Your-Application

[bajtos]

Overview

Review the content of http://loopback.io/doc/en/lb4/Testing-your-application.html and update it to match the current version of http://loopback.io/doc/en/lb4/Thinking-in-LoopBack.html

Acceptance Criteria

In LoopBack.io:

• Rewrite "Testing Your Application" to reflect the current design of loopback-next alpha, and to use the approach outlined in "Thinking in LoopBack".
• Split the content of "Testing Your Application" into two parts:
  • "High level" items should move to "Thinking in LoopBack"
  • "Details" should remain in the "Testing Your Application" page
• Dually link both pages to one another (to both give people a high-level overview of how testing should be implemented in their application, and exactly what is required to make it happen)
• Review the following list, and create a story to add what's missing to "Testing your Application":
  • test your api
  • test your sequence
  • test your controllers
  • test your repositories
  • test your services
  • validate API specs
  • create mocks
  • create stubs
  • create spys

Notes

There is a PR in loopback-next-hello-world (strongloop-archive/loopback-next-hello-world#20) that you can update to validate the existing snippets used in Thinking-in-LoopBack.html (as well as test any changes you need to make to the docs!)

This is blocked by loopbackio/loopback.io#475, which is making quite a lot of changes in pages we are going to rework.
