Can it help with asynchronous code?

Yes, it recognizes async functions and suggests appropriate #[tokio::test] patterns to ensure your concurrent logic is correctly verified.

How does this skill help with Rust error handling?

It scans functions returning Result types and identifies if there are corresponding tests that verify both the success and error variants, providing templates for matches! assertions.

Which coverage tools does it recommend?

The skill provides setup guidance and command-line instructions for industry-standard tools like cargo-tarpaulin and cargo-llvm-cov.

Can it check for edge cases?

Yes, it proactively looks for common boundary conditions like empty collections, zero values, and maximum/minimum limits that are often overlooked during development.

Does it support table-driven testing?

Absolutely. It identifies repetitive test cases and suggests refactoring them into clean, table-driven structures for better maintainability and readability.

セキュリティとテスト

Reviews Rust codebases to identify missing test cases and suggests comprehensive coverage for error paths, edge cases, and business logic.

The Rust Test Coverage Advisor is a specialized skill designed to improve the robustness and reliability of Rust applications. By monitoring new implementations and existing test modules, it proactively identifies gaps in testing strategy, such as missing Result error handling tests, neglected boundary conditions, and unverified async functions. It provides actionable code snippets for table-driven tests and recommends industry-standard organization patterns and coverage tools like Tarpaulin and LLVM-cov, ensuring your code is production-ready and battle-tested.
