Optimizing Your Agile Testing Processes

  1. 1. Optimizing Your Agile Testing Processes September 23, 2008 www.uTest.com
  2. 2. Agile Manifesto <ul><li>Individuals and interactions over processes and tools </li></ul><ul><li>Working software over comprehensive documentation </li></ul><ul><li>Customer collaboration over contract negotiation </li></ul><ul><li>Responding to change over following a plan </li></ul>
  3. 3. Standard S/W Theory Release! Requirements Analysis System Design Coding QA & Bug Fixes
  4. 4. The Reality… Release! Requirements Analysis System Design Coding QA New Requirements Redesign Coding Boss’s Pet Feature Redesign Coding
  5. 5. QA is a defensive stance… “Protect the user” mentality
  6. 6. Agile Development <ul><li>Short Development Cycles </li></ul><ul><li>(aka Iteration, Sprint, etc.) </li></ul><ul><li>Don’t over design: Only what you need for this sprint </li></ul><ul><li>Testing integral to process </li></ul><ul><li>Focus on software, not documentation </li></ul><ul><li>Design / Test / Code as a team </li></ul><ul><li>Business User is part of cycle </li></ul><ul><li>Iterative Releases </li></ul><ul><li>2-4 weeks apart </li></ul><ul><li>Unique value in each release </li></ul>
  7. 7. Is Agile New?
  8. 8. Move the deadline up! Kill all documentation! Keep coding till the day of release! This is NOT Agile!
  9. 9. Agile is VERY orderly
  10. 10. Test Driven Development Write Unit Tests Run Tests Write Some Code Run Tests Fail Fail Yes Pass More Features? No Pass Check-in
  11. 11. Sample JUnit Test Case <ul><li>Method in JUnit that: </li></ul><ul><li>Checks if the two arguments are equal </li></ul><ul><li>Displays message if assertion fails </li></ul>The functionality we are about to develop, which needs to be tested The JUnit Test Case that we are building @Test public void testAddition() { assertEquals( 12 , myMathClass.add(7,5) ); }
  12. 12. Sample Unit Test Code @Test public void testAddition() { assertEquals( 12 , myMathClass.add(7,5) ); assertEquals( 12 , myMathClass.add(5,7) ); assertEquals( 3 , myMathClass.add(3,0) ); }
  13. 13. Sample Unit Test Code @Test public void testAddition() { assertEquals( 12 , myMathClass.add(7,5) ); assertEquals( 12 , myMathClass.add(5,7) ); assertEquals( 3 , myMathClass.add(3,0) ); assertEquals( 2 , myMathClass.add(-5,7) ); assertEquals( -2 , myMathClass.add(5,-7) ); }
  14. 14. Sample Unit Test Code @Test public void testAddition() { assertEquals( 12 , myMathClass.add(7,5) ); assertEquals( 12 , myMathClass.add(5,7) ); assertEquals( 3 , myMathClass.add(3,0) ); assertEquals( 2 , myMathClass.add(-5,7) ); assertEquals( -2 , myMathClass.add(5,-7) ); assertEquals( 133332 , myMathClass.add(55555,77777) ); }
  15. 15. Sample Unit Test Code @Test public void testAddition() { assertEquals( 12 , myMathClass.add(7,5) ); assertEquals( 12 , myMathClass.add(5,7) ); assertEquals( 3 , myMathClass.add(3,0) ); assertEquals( 2 , myMathClass.add(-5,7) ); assertEquals( -2 , myMathClass.add(5,-7) ); assertEquals( 133332 , myMathClass.add(55555,77777) ); assertEquals( 6 , myMathClass.add(1,2,3) ); }
  16. 16. Don’t worry about that Failure… The Feature Is Not For This Release Don’t worry about that Failure… It’s a Known Bug
  17. 17. Testing Phases
  18. 18. Compliance Matrix Complexity <ul><li>Testing Compliance Matrix keeps getting bigger </li></ul><ul><li>For web apps, who is the customer in the team? </li></ul>1997 1999 2001 2003 2005 2007 2009 Medium Complexity: OS, Hardware, Device Drivers High Complexity: OS, Browser, Browser Settings/Plug-ins, Firewall / Anti-Virus / Filtering, Connection Speed, Language/Region Low Complexity: Browser Version Native-Code HTML Server-side Dynamic Web Apps
  19. 19. The Tester’s Role <ul><ul><li>Unit Tests = Specs </li></ul></ul><ul><ul><ul><li>QA and PM meet early </li></ul></ul></ul><ul><ul><ul><li>No more SRS  TP Alchemy </li></ul></ul></ul><ul><ul><li>Testing is part of development process </li></ul></ul><ul><ul><ul><li>Team development calls for testing frame of mind </li></ul></ul></ul><ul><ul><ul><li>In a programming team / pair, not everyone is homogenous </li></ul></ul></ul><ul><ul><li>Acceptance Testing by Customer </li></ul></ul><ul><ul><ul><li>Coordinating (and participating in) customer testing / community testing </li></ul></ul></ul>
