12. ? WHAT IS IT ALREADY?
13. It describes a cycle of interactions with well-defined “
14. outputs, resulting in the delivery of working, tested
15. software that matters. Dan North

22. Who is the user? InteractingC
23. What should the user see, here? InteractingC
24. What should happen if _____ occurs? InteractingC
25. What does “done” look like? InteractingC
26. InteractingC G C D D !@#& %* *#$! %@ &$! @#@
28. Given DescribingK Some preconditions.
29. When DescribingK The user does something.
30. Then DescribingK This should happen.
31. Scenario: User can log in Given I am on “/login” And I fill “username” with “jfox” And I fill “password” with “$3cr3t” When I press “Login” Then I should be on “/home” DescribingK
32. DescribingK Scenario: User can log in
33. DescribingK Given I am on “/login”
34. DescribingK And I fill in “username” with “jfox”
35. DescribingK And I fill in “password” with “$3cr3t”
36. DescribingK When I press “Login”
37. DescribingK Then I should be on “/home”
38. DescribingK And I should see “Welcome Jason!”

44. Given I do “2” things. TestingN
45. You can implement step definitions for undefined steps with these snippets: /** * @Given /^I do "([^"]*)" things$/ */ public function iDoThings($arg1) { throw new PendingException(); } TestingN
46. And I fill in “username” with “jfox” TestingN
47. TestingN /** * Fills in form field with specified id|name|label|value. * * @When /^(?:|I )fill in "(?P<field>(?:[^"]|\\")*)" with "(? P<value>(?:[^"]|\\")*)"$/ */ public function fillField($field, $value) { $field = $this->fixStepArgument($field); $value = $this->fixStepArgument($value); $this->getSession()->getPage()->fillField($field, $value); }
