Automated Browser Testing with Selenium and PHPUnit

As the technical co-founder of a startup faced with the challenge of delivering a secure, scalable, cross-browser payments platform with virtually no QA resources, I turned to Selenium and PHPUnit to fully automate end-to-end browser based testing. After introducing Selenium and PHPUnit, I'll demonstrate how easy it is to get started, highlight lessons learned over the past 4 years of using Selenium, and discuss the latest tools/trends from the Selenium community. Regardless of your company size, Selenium is a surefire way to improve your QA and testing process with minimal investment.

1. Automated  Browser  Testing  with   Selenium  (and  PHPUnit) Joshua  Silver VP,  Product  Development  &  co-­‐founder Patientco
2. ¡ Background ¡ Testing  at  Patientco ¡ Introduction  to  Selenium ¡ How  it  works  /  Getting  started ¡ Testing  in  the  cloud ¡ Next  Steps
3. ¡ Patientco  helps  healthcare  providers  improve  all   aspects  of  patient  financial  engagement ¡ Billing,  payments,  healthcare  integrations ¡ Founded  in  2009 ¡ We’re  hiring! ¡ www.PatientcoLife.com
4. ¡ Background: § CompSci from  GT § Helped  internationalize  CareerBuilder.com platform ¡ Technical  co-­‐founder  of  Patientco ¡ Fun  Fact:     § Travel  junkie:  25  countries  by  the  time  I  was  25
5. Develop  a  robust  payments  platform ….  that’s  cross  browser  compliant ….  that  ALWAYS  works ….  with  a  small  development  team ….  and  no  resources  for  QA
6. ¡ Payment  processing § Heavy  client  side  logic § Lots  of  hairy  javascript ¡ Healthcare § COMPLEX  business  rules § Wide  variability  in  data ¡ Browsers
7. Hospital  Usage Patient  Usage
8. ¡ Manual  QA
9. ¡ Manual  QA
10. ¡ Manual  QA ¡ Automated  testing § Unit  Testing § Integration  Testing § Full-­‐blown  front  end  testing
11. ¡ All  critical  areas  of  the  site  (payment  processing,   registration,  etc.)    are  under  full  Selenium  test   coverage ¡ 2000+  tests ¡ 10,000s  of  distinct  test  cases (Most  tests  utilize  dataProviders to  test  various   cases  with  the  same  code) ¡ Run  end-­‐to-­‐end,  takes  many  hours.
12. Percent  Lines  of  Code Test  Code Application   Code
14. ¡ Selenium  helps  you  automate  browser   based  tests  (with  recent  support  for  mobile) ¡ Write  one  test  and  run  in  all  browsers ¡ Script  complex  user  interactions,  including   AJAX,  dynamic  elements,  file  uploads,  etc. ¡ Invoked  through  PHPUnit tests
17. ¡ Selenium  1  – Remote  Control  (RC) § Javascript layer  on  top  of  browser § Largely  procedural § DEPRECATED! ¡ Selenium  2  – WebDriver § Native/direct  calls  to  browser § Largely  OO § Allows  for  complex  interactions
25. 1. Start  with  SeleniumBuilder https://saucelabs.com/builder 2. Export  test  results 3. Tweak  in  code: 1. Refactor  common  helper  functions 2. Add  dataProviders 3. Increase  number  of  asserts,  etc.
26. ¡ Huge  array  of  testing  Browser/OS  platforms ¡ Manual  test  sessions ¡ Video  and  Screenshots ¡ Mobile  testing
30. ¡ Start  small.  Test  something,  anything. ¡ Testing  should  never  be  a  separate  ticket.  It’s   a  STEP  in  a  development  ticket. ¡ Keep  an  eye  on  long  running  tests  and  try  to   consolidate  tests.   ¡ Track  which  areas  of  the  application  are   tested.
31. ¡ Official  docs: § http://www.seleniumhq.org/docs/ ¡ Testing  in  the  cloud: § https://saucelabs.com § https://www.browserstack.com/ ¡ Go  test  something!
32. ¡ With  Selenium,  you  can  automate  practically   anything! ¡ Selenium  provides  all  of  the  basic  building   blocks: § “Clicking”,  “typing”,  “dragging” § Capturing  data  elements § Conditional  logic  through  test  driver
