Testing for Confidence

Choose the test boundary from the defect you need to catch, not from the coverage number you want to report.

  1. Coverage Tells You What Ran, Not What Your Tests Would Catch
  2. Choose the Test Boundary from the Defect
  1. A Mock Fortress Tests a Call Script
  2. An Interface Does Not Make a Fake Substitutable
  3. A Surviving Mutant Is a Question, Not a Score
  4. A Characterization Test Is a Boundary, Not a Recording
  5. A Design Is Good for a Change, Not in Isolation
