- Return special value
- Set error flag
- Recover, keep going
9 Debugging
9.1 Defects
- Defect: An incorrect program code (a bug in the code).
- Infection: An incorrect program state (a bug in the state).
- Failure: An observable incorrect program behavior (a bug in the behavior).
Why Programs Fail: A Guide to Systematic Debugging, 2ed.
9.2 TRAFFIC
- Track the problem in the database.
- Reproduce the failure.
- Automate and simplify the test case.
- Find possible infection origins.
- Focus on the most likely origins:
- Code smells
- Known infections
- Causes in state, code, and input
- Isolate the cause
- Correct the defect.
