Rust Testing

The rust-testing skill enables AI agents to execute Rust unit tests directly within the agent's environment. It automates the verification of code correctness by running test suites defined in Cargo.toml and src directories, providing immediate feedback on compilation errors or failing assertions.

When to use it

• Validate new logic changes before merging code into a shared repository.
• Ensure library dependencies are correctly resolved and compatible with your Rust version.
• Automate regression checks during iterative development cycles for backend services.
• Verify that generated code adheres to expected behavior without manual intervention.

Key capabilities

• Executes cargo test commands across specified project paths.
• Captures stdout/stderr output from failing tests for debugging.
• Integrates seamlessly with Rust projects using standard Cargo structures.
• Supports both unit and integration test definitions within the crate.

Example prompts

"Run all unit tests in my Rust backend service to check for recent regressions." "Execute the test suite for the new authentication module and report any failures." "Validate that the latest dependency update doesn't break existing functionality by running cargo test."

Tips & gotchas

Ensure your project has a valid Cargo.toml file before invoking the skill, as it is required to locate test definitions. The agent will fail gracefully if no tests are found in the specified directory, so verify your test coverage first.
