4. What do you use for “in
browser” testing?

5. Selenium has some issues


6. Selenium Issues
• Reliability / Stability

8. Selenium Stability Last 2 months

9. Selenium Stability Last 12 months

10. Selenium Issues
• Reliability / Stability
• Speed

11. Build Time – 400 Selenium on 3
machines 6 parallel cores

17. Why so slow?
• Browser speed
• JS speed
• Machine speed
• External URLs

18. Selenium Issues
• Reliability / Stability
• Speed
• Internet Explorer / Browser Compatibility

21. Don’t use Selenium to test
JavaScript!
Use it to test application flow
instead.

28. Jasmine is a BDD tool
(Behavior Driven Development)

29. What is BDD
In software engineering, behavior-driven development (abbreviated BDD) is a
software development process based on test-driven development (TDD).[1][2]
Behavior-driven development combines the general techniques and principles
of TDD with ideas from domain-driven design and object-oriented analysis and
design to provide software developers and business analysts with shared tools
and a shared process to collaborate on software development.

30. BDD In the Nutshell
Write tests that describe application
flow.

31. What BDD looks like
“Purchase flow should accept VISA”

32. Jasmine Test Sample

33. It’s Just Functions!
• “describe” “context” “it”…
• Can use any JS code to make a test work

35. Jasmine Features
• Mocks / Spies
• Fixtures
• Matchers
• Setup / Teardown
• Asynchronous Support and Callbacks

36. Mocks / Spies
• Double any function
• Monitors the calls the function
• Monitors the arguments passed in
• Can create a “bare” spy
• Mock the Clock

37. Fixtures
• Adding elements to page on the fly

38. Matchers
• expect()
• toEqual()
• not()
• toBeFalsy()
• toThrow()
• Custom matchers

39. Setup / Teardown
• beforeEach()
• afterEach()

40. Asynch support
• Using spies to verify Callbacks
• runs()
• waitsFor()

41. What it is written in
• HTML
• JavaScript
• Ruby
– Rake
– ERB
– Rspec

42. Workflow in Ruby
• Rake
• ERB (Generate HTML)
• Selenium
• Tests in Loaded JS
• Rspec

43. Environments supported
• Ruby
• Rails
• Spider Monkey
• Node
• Scala
• Java
• Django
• .Net
• Perl
• HTML

44. Installation
• gem install jasmine
• jasmine init
