not as hard as you think
Agenda
- Introduction.
- Runners and frameworks.
- Unit tests.
- Integration tests.
- Running your tests.
- Summary
Introduction
What types of tests in Ember.js have we?
Acceptance
Integration
Unit
Frameworks and runners
A test runner that makes Javascript unit testing fun.
What is test runner?
Where can my tests run?
Frameworks and runners
An easy-to-use JavaScript Unit Testing framework.
What is testing framework?
Unit tests
Test a small piece of code and ensure that it is working
Why unit tests instead of acceptance?
When should I bother to write it?
How to do it?
Methods, computed properties, state, helpers, utilities
Create an Ember.Object, set it, execute a method and test it!
Blazing fast, helps to find edge cases, helps to reason about
Unit tests
Examples
Integration tests
Test components by rendering them in tests scope
Why integration tests instead of acceptance?
When should I bother to write it?
How do I test it?
Actions, events, rendering order.
Render the component and assert using jQuery on test's scope
Much faster, easy to maintain, don't need so many dependencies
Integration tests
Examples
Running your tests
Tips & Tricks
Tip #1: Don't use ember test
Tip #2: Just visit http://localhost:4200/tests
Tip #3: Have opened console there and make use of debugger
Tip #4: Don't run all of the tests while working on them - use filters
Good practices
Don't avoid testing in Ember.js
Don't accept not-tested code during code review
Don't know how to test? Ask on #emberjs
