5. TESTAUTOMATION WHY?
NOT to replace people
To save time and to reinvest that time into manual testing
To get early and instant feedback
Regression testing only
Safety net
MICHAEL PALOTAS - EBAY INTERNATIONAL 5
6. A FEW THOUGHTS ABOUT AUTOMATION
Manual testing is still very important
Do not compensate missing unit tests with E2E tests
E2E tests are “expensive”, so keep them to the minimum
Automation is software development
Be careful with record & playback tools
Automate the repetitive tasks (regression)
Build testability into your product
To all managers: YES you will need to invest, nothing comes for free

8. WHY END TO END TESTING IS SO IMPORTANT
Because it is the most difficult way to test
Because that’s what our users do
Because that’s how we can verify if the whole system works
