What is the 'pesticide paradox' in testing?
- 1Running the same tests repeatedly stops finding new defects
- 2Automated tests become slower the more often they run
- 3Fixing one bug always creates a new bug elsewhere
Show the answer
Correct answer: Running the same tests repeatedly stops finding new defects
Explanation
Tests that always pass keep the old bugs out but no longer discover new ones. Teams review and update tests, add new data and use exploratory testing to keep finding problems.
