Intro | DESCRIPTION Who am I?
Webinar | Content Unit tests UI tests Continuous Integration •
Writing a unit test • Using PhantomJS • Hello world sample • Event recorder intro • Testing an Ext JS cmp • Recording a UI test • TeamCity • Code Coverage • Statistics • Cloud Testing
Intro | DESCRIPTION Less Theory, More Real World
Intro | WHY Why Testing?
Intro | WHY Hands up: Who is testing their JS?
Intro | WHY
Intro | WHY 1. Productivity & confidence in code 2.
Frameworks contain bugs 3. So does your code (and mine) 4. Refactoring & code handover 5. Fix bugs once
Intro | TERMINOLOGY Terminology: what does testing mean for a
JS developer?
Intro | TERMINOLOGY Unit tests, UI tests, Application tests..?
Intro | TERMINOLOGY Unit tests App Tests UI tests
Testing With Siesta Introduction
Intro | Testing with Siesta • runs in any browser
• is written in plain JS • is sandboxed by default A Siesta test…
Intro | Testing with Siesta • can do both UI
and unit testing • can be automated using PhantomJS or Selenium WebDriver • can detect leaked global variables A Siesta test…
Intro | Testing with Siesta describe('A simple Model test', function
(t) { t.it('Should do something', function(t) { // Test things t.expect(1).toBe(1); }); });
Unit Tests Red, Green, Refactor
Unit tests | Intro •Unit tests usually only involve “raw”
JS •Run very fast •Perfect for pre-commit hooks •Disable sandboxing if possible
Unit tests | Intro •Should be your #1 priority •Cover
your most important JS classes •Run often, before commit, daily, nightly. •Use TDD approach + BDD style for readability
Unit tests | TDD basics 1. Make the unit test
fail 2. Implement 3. Make the test pass 4. Refactor, Repeat
Unit tests | Writing a unit test Unit testing demo
Testing your UI Functional testing
UI tests | Intro Manually writing UI tests takes time
UI tests | Intro UI tests are more fragile &
run slower than unit tests
UI tests | Intro Understanding CSS and ComponentQuery is key
UI tests | Intro •UI “unit test” of a single
UI component •Or Application test, open index.html and test it Two main types of UI tests
UI tests | Intro UI Unit test demo
UI tests | Intro Siesta Event Recorder
UI tests | Event recorder •Great for application tests •Records
user actions: clicks, types, drag drop •Exports actions to a Siesta test case •Can be used by a non-programmer •Big timesaver
UI tests | Event recorder Let’s try the recorder
UI tests | Monkey tests Monkey testing
UI tests | Monkey tests •Random UI testing •Clicks, drags
etc. in your UI •Finds unhandled exceptions •Free testing help. 0€
UI tests | Monkey tests Cost breakdown: 5€ * 0
= 0 5€
Continuous Integration TeamCity, Code Coverage & Statistics
Continuous Integration | Intro •Bryntum uses TeamCity, Siesta integrates with
others (Jenkins…) •Test suites run every 2 hours in Chrome •Full test suites executed nightly •Reports, statistics, charts and code coverage
Continuous Integration | TeamCity Let’s checkout TeamCity
UI tests | Cloud testing So…running in multiple browsers?
Continuous Integration | Cloud testing •Need to create Virtual Machines
for each version of IE •Total: Chrome, Safari, FF, IE 7-11 => 7 VMs •Managing such a farm can be very time consuming
Continuous Integration | Cloud testing •Siesta integrates with both BrowserStack
and Sauce Labs •Run tests easily in any OS and Browser combination •No need to setup your own VM farm •Read more on the Bryntum blog…
Continuous Integration | Cloud testing Launching tests in BrowserStack
