First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/organize-tests/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

Skill: organize-tests

Organize tests by isolation requirements, adhering to PTY conventions and subprocess isolation patterns.

When to Use

  • Adding new tests to the codebase.
  • Refactoring existing tests.
  • Organizing test modules and directories.
  • Ensuring PTY tests follow the "Run with:" and deadlock prevention conventions.

Instructions

1. Identify Isolation Requirements

Choose the correct directory based on why the test needs isolation. This maintains low cognitive load for future developers.

See Taxonomy for directory details.

2. Follow PTY Conventions

PTY tests are complex and prone to deadlocks (especially on macOS). Strict adherence to naming, documentation, and resource management is mandatory.

See PTY Conventions for details.

3. Orchestrate Process Isolation

Tests that pollute global mock state (e.g., static Mutexes) must be isolated into a single subprocess and run sequentially.

See Examples for macro usage.

4. Wire Up Modules

Always ensure test modules are visible for both tests and documentation using #[cfg(any(test, doc))].

#[cfg(any(test, doc))]
pub mod unit_tests;
#[cfg(any(test, doc))]
pub mod process_isolated_tests;
#[cfg(any(test, doc))]
pub mod my_module_integration_tests;
