24 Behavior Driven Development with Behat Background & Tables All Scenarios Many items

25 Behavior Driven Development with Behat Tables

26 Behavior Driven Development with Behat Contexts Drupal - users, terms, and nodes DrupalRaw - functionality Mink - regions and forms Markup - tags, classes, & attributes Message - notice, warning, & error Drush - call commands directly

27 Behavior Driven Development with Behat Custom Contexts FeatureContext.php file CustomContext class 1. Write the step 2. Run the test (it will fail) 3. Copy the generated snippet

28 Behavior Driven Development with Behat Custom Contexts

29 Behavior Driven Development with Behat Custom Contexts

30 Behavior Driven Development with Behat Custom Contexts 1. Delete exception 2. Add code 3. Test again

31 Behavior Driven Development with Behat Args in Custom Contexts

32 Behavior Driven Development with Behat Args in Step Definitions Given I am logged in as a user with the 'Administrator' role When I create a webform "a_test_webform"

41 Unit Testing with PHPUnit Unit

42 Unit Testing with PHPUnit Assertions Equals = Same == True / False PHPUnit Documentation Appendix A

43 Unit Testing with PHPUnit Kernel API Decoupled Setup Config

44 Unit Testing with PHPUnit Enable modules

45 Unit Testing with PHPUnit Setup Top of the class Applies to all test functions Set up the parent first

46 Unit Testing with PHPUnit Install DB & Config (Entity) Schema Configuration

47 Unit Testing with PHPUnit setup

48 Unit Testing with PHPUnit Install Fields Get from configuration management Create n Save Storage Field

49 Unit Testing with PHPUnit Functional Enable modules Paths! Web assert

54 Unit Testing with PHPUnit assertsession waitfor AjaxToFinish, Button, Element(Visible), Field, Link waitonautocomplete responsecontains isvisible

55 Unit Testing with PHPUnit Test Doubles Return a value without the object

56 Unit Testing with PHPUnit Mock Objects

57 Unit Testing with PHPUnit Base Classes Common setups Nested levels

58 Unit Testing with PHPUnit Traits Code reuse in many classes Groups sets of methods Can not be instantiated

59 Unit Testing with PHPUnit Reflection Trait Test protected / private methods

60 Unit Testing with PHPUnit Trait in action

61 Unit Testing with PHPUnit Data Providers Run same test with different datasets

62 Unit Testing with PHPUnit Named Data Providers Named dataset via associative array

63 Unit Testing with PHPUnit Debugging print_r($whatever); Screenshots Reports Error/failure messages

64 Unit Testing with PHPUnit Running tests phpunit --options arguments blt:tests phpunit = pass, E = error, F = Failure

65 Unit Testing with PHPUnit Happy & Sad Paths Test failure as well as success expectexception() Code, Message, MessageRegExp
