Software Testing Quotes

  1. “Testers don’t like to break things; they like to dispel the illusion that things work.”— Kaner, Bach, Pettichord

  2. “Pretty good testing is easy to do (that’s partly why some people like to say ‘testing is dead’– they think testing isn’t needed as a special focus because they note that anyone can find at least some bugs some of the time). Excellent testing is quite hard to do.”— James Bach

  3. “A pinch of probability is worth a pound of perhaps.”— James Thurber

  4. “Testing is not responsible for the bugs inserted into software any more than the sun is responsible for creating dust in the air.”— Dorothy Graham

  16. “Testing leads to failure, and failure leads to understanding.” — Burt Rutan

  17. “The more effort I put into testing the product conceptually at the start of the process, the less I effort I had to put into manually testing the product at the end because less bugs would emerge as a result.” — Trish Khoo

  18. “I do believe it’s important for testers to know the market that their client or their employer is in and the reason for that is if you understand what risks your client is facing and you understand what the competing products are and where the challenges lie in the market, you can plan your testing accordingly.” — Karen N. Johnson

  19. “I think when you hear the phrase ‘it’s just test code’. To me that’s a code smell.” — Alan Page

Quotes About Bugs

  1. “If we want to be serious about quality, it is time to get tired of finding bugs and start preventing their happening in the first place.”— Alan Page

  2. “More than the act of testing, the act of designing tests is one of the best bug preventers known.”— Boris Beizer

  3. “Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.”— Brian W. Kernighan

  4. “When debugging, novices insert corrective code; experts remove defective code.”— Richard Pattis

  5. “It’s hard enough to find an error in your code when you’re looking for it; it’s even harder when you’ve assumed your code is error-free.”— Steve McConnell

  6. “Beware of bugs in the above code; I have only proved it correct, not tried it.”— Donald Knuth

Quotes About Automation

  1. “Automated scripts are checking known paths for expected results. That’s not truly testing. Testers discover the unknown, and this skill is still very much so needed, whether there’s automation or not. Without human intuitive exploration, a team may be blind to their most expensive bugs.”— Angie Jones

  2. “Also common is the test automation group zombie. This zombie is the practice of assigning test automation to a dedicated team of test automators. The appeal is that we can keep developers focused on writing new code instead of writing and maintaining automated tests. The danger is that test automation inevitably lags development, so feedback from testing is delayed in a way that significantly reduces its value.”— Dale Emery.

  3. “Automation does not do what testers used to do, unless one ignores most things a tester really does. Automated testing is useful for extending the reach of the testers work, not to replace it.”— James Bach

  4. “It’s automation, not automagic.” — Jim Hazen

  3. “To successfully implement continuous delivery, you need to change the culture of how an entire organization views software development efforts.”— Tommy Tynja

  5. “There’s this notion in agile teams of delivering a vertical slice of functionality in each sprint. You can’t do that if the team doesn’t represent all aspects of the slice. So the magic is in composing the team with a broad set of skills that’s focused on delivering value.”— Mary Thorn
