Rust test suites often drift into unclear coverage, brittle assertions, and missing invariants, making regressions harder to detect and trust harder to build.
Use the improve-rust-tests skill to audit your Rust project’s existing unit/integration/doctest/property tests, propose a prioritized set of improvements, and implement the changes that best strengthen behavior coverage and invariants.

Rust test coverage improves by auditing test placement, coverage shape, and evidence quality. The skill evaluates existing tests against Rust testing guidance, proposes prioritized improvements, and reorganizes unit and integration tests vertically for targeted behaviors.
Adding property tests requires evaluating missing invariants in your current suite. The skill identifies where property testing strengthens behavior coverage, proposes specific changes before editing, and verifies the additions using final gates like nextest and clippy.
TDD-style test refactoring works by building or refactoring tests vertically for targeted behaviors, then cleaning up redundant or misleading tests. The skill aligns execution with TDD guidance and requires candidate listing before any edits are applied.
Yes, nextest and clippy are used as final verification gates. The skill requires running these tools, along with fmt and doc tests when applicable, to ensure that test upgrades maintain code quality and pass all formatting and linting checks.
Rust tests become brittle due to drifted coverage and missing invariants. The skill fixes this by performing an evidence-grounded review of readability and fit, then upgrading assertions and test organization to make regressions easier to detect.
Yes, a baseline command run is required. The skill mandates running a baseline, listing candidate improvements, and executing vertical behavior-focused test changes before applying final verification gates to ensure evidence-driven coverage.
