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

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

s

Manual Tests

Integration Tests

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
