Test Runner Skill

This skill executes the test suite for the codebase.

When to use this skill

• •When the user asks to "run tests", "check my code", or "verify changes".
• •When the user specifically asks to test a file (e.g., "test the auth service").
• •After refactoring code to ensure no regressions were introduced.

Instructions

1. •

   Environment Check:

   • •specific checks: Ensure node_modules exists. If not, run yarn install first.
2. •

   Determine Scope:

   • •If the user provided a specific file or feature name (e.g., "test login"), append that filename or pattern to the command.
   • •If the user request is generic (e.g., "run all tests"), execute the base command.
3. •

   Execution:

   • •Run the command: yarn test <optional-arguments> in the terminal.
4. •

   Analysis:

   • •Read the terminal output.
   • •If tests pass: Confirm success to the user briefly.
   • •If tests fail:
     • •List the specific test cases that failed.
     • •Analyze the error message and stack trace.
     • •Remove unnecessary details from the output that would bloat the context window.
     • •Suggest a potential fix for the failure if the cause is obvious.

Constraints

• •Do NOT run tests in "watch" mode.
• •Do NOT attempt to fix code automatically. Just report the errors first.

Examples

User: "Run the tests" Action: yarn test

User: "Test the user controller" Action: yarn test user.controller.spec.ts (or similar matching file)
