The document discusses integration testing for web applications in Python. It describes integration tests as high-level tests that simulate browser interactions and span multiple components. It then discusses different tools for integration testing like Selenium, Splinter and a custom library called easy_integration that aims to simplify the process. The key benefits of easy_integration are that it runs on top of Splinter and Selenium without requiring manual browser object management and has a simple API for common test actions.

1. Integration Testing In Python And why I Love it so Much Mike Leone Panoptic Development February 29, 2012

2. What are web application integration tests?

3. High-level TESTS

4. High-level TESTS That simulate Web Browser Interaction

5. A.K.A. Acceptance Testing Browser Testing

6. Web apps? Unit testing? Integration testing?

7. EXAMPLE Test that a user can log in to your web app

8. EXAMPLE

9. USE CASES?

10. Customer-tracked user stories

11. Customer-tracked user stories “ A user should be able to create a profile and update their address”

12. High-level tests that span multiple components

13. High-level tests that span multiple components Beyond the scope of unit tests

14. Large, inherited applications

15. Large, inherited applications A less overwhelming way to track big feature sets

16. Non-application updates

17. Non-application updates Testing client applications after a data migration or infrastructure upgrades

18. But integration tests can test low-level logic too!

19. But integration tests can test low-level logic too! So let's write integration tests only, and forgo unit tests!

21. Pick your Battles

24. There's more state to manage

26. There's more state to manage

27. They take longer to update

29. There's more state to manage

30. They take longer to update

31. Very simple app or CMS?

33. Existing tools

34. Existing tools: Bare-metal selenium

38. Existing tools: Splinter

39. from splinter.browser import Browser browser = Browser() browser.visit('http://google.com') browser.fill('q', 'splinter - python acceptance testing for web applications') browser.find_by_css('.lsb').first.click() if browser.is_text_present('splinter.cobrateam.info'): print "Yes, the official website was found!" else: print "No, it wasn't found... We need to improve our SEO techniques" browser.quit()

40. from splinter.browser import Browser browser = Browser() browser.visit('http://google.com') browser.fill('q', 'splinter - python acceptance testing for web applications') browser.find_by_css('.lsb').first.click() if browser.is_text_present('splinter.cobrateam.info'): print "Yes, the official website was found!" else: print "No, it wasn't found... We need to improve our SEO techniques" browser.quit() Much better!

42. Navigation still a bit clunky

43. The Ruby community is obsessed With testing

44. The Ruby community is obsessed With testing How do they do it?

45. # Example: Capybara test framework include Rack::Test::Methods def test_it_says_welcome get '/' click 'link text' assert response.body.include?(“Welcome!”) end

46. # Example: Capybara test framework include Rack::Test::Methods def test_it_says_welcome get '/' click 'link text' assert response.body.include?(“Welcome!”) end

47. # Example: Capybara test framework include Rack::Test::Methods def test_it_says_welcome get '/' click 'link text' assert response.body.include?(“Welcome!”) end That's what I want

48. Enter easy_integration!

49. Enter easy_integration! The lightweight testing lib I wrote.

55. Test server running, port 8001

57. click()

58. fill_in()

59. select()

60. displays()

62. click()

63. fill_in()

64. select()

65. displays() That's it

66. DEMO TIME (Django example)

68. Lettuce

70. Manage time-consuming database transactions
