End-to-end Testing

[KevinMulhern]

Summary

We need a lesson to introduce students to end-to-end testing and what to test with it.

Acceptance Criteria

Lesson content should cover:

• [ ] What are end-to-end tests?
• [ ] What to test - test the happy path and don't try to cover all edge cases.
• [ ] The testing pyramid.
• [ ] Exercise: write some more end-to-end tests for the example project.
