What it does
Iteratively improve Fallow Rust test coverage with cargo-llvm-cov, prioritizing meaningful untested behavior and preserving runtime correctness.
Coverage loop
- Capture a coverage baseline with the repository-supported command.
- Select uncovered behavior by risk, not by easiest lines.
- Add behavior-focused tests that survive refactors.
- Re-run targeted tests and the same coverage command.
- Keep only tests that improve meaningful coverage or lock a real invariant.
- Repeat until the selected risk area is covered or remaining gaps require a separate design change.
- Run
review.
Do not add assertions that merely execute code without checking behavior.
