Agile Methods and Quality Agile principle #9: “Continuous attention to technical excellence and good Agile Methods and Quality Agile principle #9: “Continuous attention to technical excellence and good design enhances agility. ” Technical excellence is achieved in many ways, but all include a constant focus on quality. Observation: Agile projects emphasize quality much more than traditional. © www. synerzip. com / www. threebeacons. com 2012 3

Definition of Done • Ensure that a solid “definition of done” is developed up Definition of Done • Ensure that a solid “definition of done” is developed up front, for example: • All new/modified code reviewed • Coding standards compliance • Static purification with 0 errors and 0 warnings • Dynamic purification – no memory leaks • All methods <= cyclomatic complexity 10 • All code checked in to Subversion prod branch • 80% code coverage – unit testing • Zero known bugs • Acceptance tests verified by QA on clean system • Acceptance tests verified by customer or proxy www. threebeacons. com white paper “The Three Beacons of Software Project Success” © www. synerzip. com / www. threebeacons. com 2012 19

Sashimi Acceptance Testing Iteration 1 Iteration 2 Iteration 3 • Verify functional slices • Sashimi Acceptance Testing Iteration 1 Iteration 2 Iteration 3 • Verify functional slices • Verify user stories satisfy acceptance test cases • Adhere to definition of done • Verify incremental integration • “Unofficial” testing for feedback • Exploratory testing © www. synerzip. com / www. threebeacons. com 2012 20

Sashimi Acceptance Testing QA assists iteration planning QA writes additional tests and creates automation Sashimi Acceptance Testing QA assists iteration planning QA writes additional tests and creates automation Deliver multiple times to QA in a sprint QA tests and gives feedback Dev concentrates on bugfixes several days prior to sprint end QA wraps up with final acceptance http: //edgehopper. com/qatesting-in-an-agile-environment/ © www. synerzip. com / www. threebeacons. com 2012 21

Test Case Automation • Choose appropriate tool for your needs • Leverage previous experience Test Case Automation • Choose appropriate tool for your needs • Leverage previous experience and use of tools • Focus on user actions and expected results for acceptance test cases • Anticipate what the result might look like - Screen mocks - Design diagrams - Collaborative discussions • Code the automation script • Run it prior to receiving the software - Verify the test case fails - Prevents the test case from accidentally passing - Similar to TDD • Once software is received, verify the test case works © www. synerzip. com / www. threebeacons. com 2012 22

Common Mistakes Common Mistakes

Common Mistakes • QA sashimi tests run in subsequent sprint - Violates “potentially shippable Common Mistakes • QA sashimi tests run in subsequent sprint - Violates “potentially shippable product increment” • Mini-waterfall handoff to QA within sprint - Violates lean/agile principles • Manual testing of sashimi slices - Latency of feedback - You won’t have time • QA not involved in user story development - Violates holistic team-based approach • QA not involved in release/sprint planning - Violates “committed team” principle • QA not physically located with project team - Violates “co-location” principle • Others? © www. synerzip. com / www. threebeacons. com 2012 29

Conclusion Conclusion

Take-Aways • Agile – much more emphasis on QA than traditional approach • QA Take-Aways • Agile – much more emphasis on QA than traditional approach • QA test specialist is an integral member of the development team! • Being a QA tester is much more prestigious in Agile - Peer with software developers - Respect is shown through better communication & collaboration - Required involvement up-front and throughout! • Different role, different responsibilities, different skills • Agile – much better chance at delivering high-quality software on time © www. synerzip. com / www. threebeacons. com 2012 31
