Today’s  goal

• Set  up  and  use  Selenium  IDE• Record  UA  tests• Convert  to  PHPUnit• Run  con'nuously• Mul'  browser  support

⚠DISCLAIMERS 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”!

Checklist  for  web  applica'ons

8

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,  …

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

Browser  support

Benefits

• run  your  tests  on  mul'ple  browsers• detect  flaws  in  specific  browsers  (e.g.  IE6)-­‐ adapt  your  apps  to  solve  these  flaws
