This document discusses using functional test automation to prevent defects from escaping the development phase. It recommends automating acceptance tests during development to catch bugs early from the user perspective. The process involves preparing for automation by exploring and selecting test candidates, automating the tests as close to development as possible, and repeating the automation across areas, platforms and versions to prevent regression bugs. Continuous integration and handling test errors are also suggested to provide feedback and react to issues identified through automation. The overall goal is to shift testing left in the development cycle through early and frequent automation from a user perspective.

- 1. Version 2.5© Bredex GmbH Using Functional Test Automation to Prevent Defects from Escaping the Development Phase Alexandra Schladebeck
- 2. 2 Agenda Prevention versus cure Testing close to development Focus on the user perspective Automation as a quality-enhancing activity Open points for the test process Checklist and conclusions
- 3. 3 Prevention versus cure Prevention? Discovery and removal (or: seek and destroy)
- 4. 4 How soon is now?
- 5. 5 Software, defend yourself! Justification Test criteria During development Frequently Regardless of model… More information is beneficial As early as possible
- 6. 6 Focusing on what‘s important What informaton do we want? What sources are available to us? What are our priorities? Our focus: customer perspective … the perspective with which it will be used
- 7. 7 Use test automation to test… Automate acceptance tests during development ATDD / In parallel / Just after The early automator gets the worm Steps… Review Automate Repeat (React)
- 8. 8 Step 1: Preparing for automation Explore Read, talk, prototype, document, play Set the bar What is good enough Tests and checks Select automation candidates
- 9. 9 Bugs prevented in step one Case 1: Remembered report Report written during test Report generated after test
- 10. 10 Bugs prevented in step one Case 2: Forgotten option
- 11. 11 Step 2: Do the automation As close as possible Be a user while writing the test Different paths and alternatives while designing / testing Exactness for automation Added bonuses Usability testing Open questions
- 12. 12 Step 2: Do the automation Long-life tests Test structure Levels of detail Small use cases Independent tests Plan for change
- 13. 13 Bugs caught in step two Enter customer name Enter address Enter telephone number Leave field via enter Enter customer name Enter address Enter telephone number Don‘t leave field / leave field via click
- 14. 14 Bugs caught in step two Validation PDF Library Mandatory fields with * Mandatory fields validated by program …all of them? … NoClassDefFound
- 15. 15 Step 3: Lather, rinse, repeat Activity of automating test has gathered all information it can? Multiply Same test new area of application Same test another platform Same test new software versions
- 16. 16 Step 3: The glossy finish Continuous integration Error handling in tests
- 17. 17 Bugs prevented by step three Case 1: Multiplication error Case 2: Regression error OK OK OK Failed
- 18. 18 Step 4: React
- 19. 19 Step 4: React
- 20. 20 What have we got so far?
- 22. 22 Checklist Add the test perspective Tester, User, Documentation Start automating As close as possible Explicit tests Find ways to gain feedback CI, Show & Tell, Docu React to feedback
