10 Agile Testing

11 What is Agile testing? The job of tests, and the people that develop and run tests, is to prevent defects, not to find them - Mary Poppendieck

12 Agile Test approach An agile test approach Adheres to the principles of Agile & Lean Embraces changes late in development Handles testing and development at the same time Works towards potential release every N th week (that is tested and done) Incorporates and utilizes a cross-functional team Introduces demands on test environment and support processes Works with a test base that evolves with knowledge

13 Agile test quadrants Business facing Automated & Manual Manual Supporting the team Functional Tests Story Tests, A-TDD Prototypes Simulations Examples & Guides TDD & Unit Tests Component Test Integration Tests Exploratory Testing Scenarios Usability Testing User Acceptance Testing Alpha/Beta Performance, Load, Security testing ility -testing Critique product Automated Technology facing Automated & Tools

14 An agile test approach (Example) For every feature (within every sprint): Product Owner (and if possible the customer) involved in design and prototyping Developed using TDD and ATDD Pair Programming (and/or Code Review) Usability Testing Integration Testing (Continuous Integration and Automated integration tests) For every sprint: Exploratory Testing User Acceptance Testing Performance testing Complete Regression Testing Customer Acceptance Testing Sprint 6 Sprint 7 Sprint 8 Sprint 8

18 The Team & the Individual

19 Personality and relations Agile development introduces demands on peoples personality! Requires Pro-active mentality Nothing is served on a silver plate Requires more collaboration and communication skills Hidden conflicts surface, new conflicts arise Everyone have to unlearn and relearn Staff turn-over I I just just work here We have always done it it like like this
