Nothing is as frustrated as deploying a new release of your web application to find out functionality you had doesn't work anymore. Of course you have all your unit tests in place and you run them through your CI environment, but nothing prepared you to a failing javascript error or a link that doesn't work anymore. Welcome to User Acceptance testing or UAT. Before you start putting real people in front of your application, create macros and export them as PHPUnit test classes. Then run them in an automated way just like your unit tests and hook them into your CI. In this talk I will show you how easy it is to create Selenium macros that can be converted into PHPUnit scripts and run automatically on different virtual machines (VM's) so you can test all different browsers on a diversity of operating systems.

UA testing with Selenium and PHPUnit - PFCongres 2013

  1. 1. UA  Tes'ng  with Selenium  and  PHPUnit PFCongres  2013  -­‐  Utrecht
  2. 2. 2 • PHP  Consultant • President  PHPBenelux • Conference  speaker Michelangelo  van  Dam
  3. 3. 3
  4. 4. Today’s  goal • Set  up  and  use  Selenium  IDE • Record  UA  tests • Convert  to  PHPUnit • Run  con'nuously • Mul'  browser  support 4
  5. 5. 5 DISCLAIMER S E L E N I U M T E S T S A R E N OT A REPLACEMENT FOR REGULAR UNIT TESTING. THEY ONLY PROVIDE AN ADDITIONAL SET OF TESTS FOCUSED ON USER ACCEPTANCE AND USER EXPERIENCE TESTING. For more information about unit testing, please see my other material on www.slideshare.net and www.speakerdeck.com. Search for “dragonbe”!
  6. 6. User  Acceptance 6
  7. 7. 7 “Acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.” -- source: wikipedia
  8. 8. Checklist  for  web  applica'ons 8
  9. 9. 9 Func'onal  tes'ng • Test  func'onal  requirements -­‐ e.g.  no  access  to  profile  without  authen'ca'on • Test  UI  elements  on  the  web  interface -­‐ e.g.  buRons,  form  elements,  AJAX  controls,  …
  10. 10. A  word  of  cau'on! 10 • UA  tests  only  test  generated  output -­‐ not  a  replacement  for  unit  tes'ng • UA  tests  are  heavily  depending  on  DOM -­‐ changes  to  the  DOM  might  lead  to  failing  UAT
  11. 11. Browser  support 11
  12. 12. Selenium  to  the  rescue 12
  13. 13. Plugin  for  firefox 13
  14. 14. Get  the  plugin  (demo) 14
  15. 15. Let’s  get  started 16
  16. 16. Pick  a  test  case 17
  17. 17. Issue  #7 18
  18. 18. Verify  this  issue  on  PROD 19
  19. 19. 20
  20. 20. Fix  the  issue 21
  21. 21. Run  test  to  see  it’s  fixed 22
  22. 22. 23
  23. 23. 24 Save  your  test  as  .html
  24. 24. It’s  that  easy! 25
  25. 25. Automated  Tes'ng 26
  26. 26. PHPUnit  to  the  rescue 27
  27. 27. Export  to  PHPUnit 28
  28. 28. The  PHPUnit  TestCase 29 <?php class Example extends PHPUnit_Extensions_SeleniumTestCase { protected function setUp() { $this->setBrowser("*chrome"); $this->setBrowserUrl("http://www.theialive.com/"); } public function testMyTestCase() { $this->open("/"); $this->click("link=login"); $this->waitForPageToLoad("30000"); $this->type("id=email", "dragonbe+tek13@gmail.com"); $this->type("id=password", "test1234"); $this->click("id=signin"); $this->waitForPageToLoad("30000"); $this->click("link=Test demo"); $this->waitForPageToLoad("30000"); $this->assertEquals("Done", $this->getText("xpath=//th[5]")); $this->click("link=[EDIT]"); $this->waitForPageToLoad("30000"); $this->assertTrue($this->isElementPresent("id=done")); $this->click("link=sign off"); $this->waitForPageToLoad("30000"); } } ?>
  29. 29. Change  class  name 30 <?php class Example extends PHPUnit_Extensions_SeleniumTestCase { protected function setUp() { $this->setBrowser("*chrome"); $this->setBrowserUrl("http://www.theialive.com/"); } public function testMyTestCase() { $this->open("/"); $this->click("link=login"); $this->waitForPageToLoad("30000"); $this->type("id=email", "dragonbe+tek13@gmail.com"); $this->type("id=password", "test1234"); $this->click("id=signin"); $this->waitForPageToLoad("30000"); $this->click("link=Test demo"); $this->waitForPageToLoad("30000"); $this->assertEquals("Done", $this->getText("xpath=//th[5]")); $this->click("link=[EDIT]"); $this->waitForPageToLoad("30000"); $this->assertTrue($this->isElementPresent("id=done")); $this->click("link=sign off"); $this->waitForPageToLoad("30000"); } } ?> class MarkTaskDoneTest extends PHPUnit_Extensions_SeleniumTestCase
  30. 30. The  PHPUnit  TestCase 31 <?php class MarkTaskDoneTest extends PHPUnit_Extensions_SeleniumTestCase { protected function setUp() { $this->setBrowser("*chrome"); $this->setBrowserUrl("http://www.theialive.com/"); } public function testMyTestCase() { $this->open("/"); $this->click("link=login"); $this->waitForPageToLoad("30000"); $this->type("id=email", "dragonbe+tek13@gmail.com"); $this->type("id=password", "test1234"); $this->click("id=signin"); $this->waitForPageToLoad("30000"); $this->click("link=Test demo"); $this->waitForPageToLoad("30000"); $this->assertEquals("Done", $this->getText("xpath=//th[5]")); $this->click("link=[EDIT]"); $this->waitForPageToLoad("30000"); $this->assertTrue($this->isElementPresent("id=done")); $this->click("link=sign off"); $this->waitForPageToLoad("30000"); } } ?> protected function setUp() { $this->setBrowser("*iexplore"); $this->setBrowserUrl("http://www.theialive.com/"); $this->setHost('192.168.56.101'); $this->setPort(12666); }
  31. 31. Meaningful  method  name <?php class MarkTaskDoneTest extends PHPUnit_Extensions_SeleniumTestCase { protected function setUp() { $this->setBrowser("*iexplore"); $this->setBrowserUrl("http://www.theialive.com/"); $this->setHost('192.168.56.101'); $this->setPort(12666); } public function testMyTestCase() { $this->open("/"); $this->click("link=login"); $this->waitForPageToLoad("30000"); $this->type("id=email", "dragonbe+tek13@gmail.com"); $this->type("id=password", "test1234"); $this->click("id=signin"); $this->waitForPageToLoad("30000"); $this->click("link=Test demo"); $this->waitForPageToLoad("30000"); $this->assertEquals("Done", $this->getText("xpath=//th[5]")); $this->click("link=[EDIT]"); $this->waitForPageToLoad("30000"); $this->assertTrue($this->isElementPresent("id=done")); $this->click("link=sign off"); $this->waitForPageToLoad("30000"); } } ?> 32 public function testMarkTestAsDone()
  32. 32. startSeleniumStandAlone.BAT 33 "C:Program FilesJavajre7binjava.exe" -jar "C:Usersuser Downloadsselenium-server-standalone-2.28.0.jar" -port 12666
  33. 33. Now  run  your  tests 34
  34. 34. How  it  runs  on  the  node 36
  35. 35. Advantages 38 • You  can  start  tes'ng  immediately • Even  test  “hard  to  test”  kind  of  situa'ons • More  nodes  for  parallel  tes'ng • Tes'ng  different  browsers  and  plaeorms • Con'nuous  Integra'on  possible
