A successful example tests one path. To discuss coverage, also consider:
- Source coverage: which provisions are included or excluded, and why?
- Conditions and exceptions: is there a case for each important branch?
- Boundaries: equality at a threshold, adjacent dates, and extreme values.
- Missing facts: do unknowns remain unknown?
- Conflicts: what happens when grounds support different conclusions?
- Versions: does changing the applicable edition change the answer?
Share a rule and a set of examples you trust. What additional case might reveal a gap?
