Fundamental Principles Of Testing – ISTQB

  1. Testing shows the presence of bugs.
  2. Exhaustive testing (testing all possible data combinations) is impossible.
  3. Early testing saves money.
  4. Defect clustering happens. If there is a bug in one part of the software, chances are there are other, related bugs nearby.
  5. “The pesticide paradox”: continuing to run the same tests won’t find new bugs.
  6. Testing is context dependent. Testing is done differently in different contexts.
  7. Software with no known errors is not necessarily ready to be shipped. Does it match user/business expectations?
