Ln 782 Test Runner

What it does

The Ln 782 Test Runner skill automates testing workflows for various project types. It detects test frameworks used in a project, executes all associated test suites, and provides detailed reports on the execution results. The tool can also generate coverage reports if enabled, providing insights into code coverage during testing. This skill is designed to be a standalone component within a larger development pipeline.

When to use it

• Standalone test execution: Run tests independently without an existing CI/CD pipeline.
• CI/CD pipeline test step: Integrate automated testing as part of a continuous integration and continuous delivery process.
• Verification of build quality: Assess the success or failure of builds by running comprehensive test suites.

Key capabilities

• Test framework auto-detection: Identifies test frameworks like Vitest, Jest, xUnit/NUnit, pytest, go test, and cargo test based on project configuration files.
• Test suite execution: Runs tests for each detected framework using appropriate command-line arguments.
• Result parsing: Extracts key metrics from test output, including pass/fail counts, skipped tests, and total duration.
• Coverage report generation (optional): Generates code coverage reports using tools like c8/istanbul, coverlet, pytest-cov, go test -cover, or cargo-tarpaulin.
• Reporting: Provides structured results including metrics such as total, passed, failed, skipped, duration, linesCovered, linesTotal, and percentage.

Example prompts

• "Run all tests in the project."
• "Execute the test suite and generate a coverage report."
• "Detect the testing framework used in this project and run its associated tests."

Tips & gotchas

• Mandatory Read: Ensure you load shared/references/ci_tool_detection.md to properly configure the skill for your environment. This file contains crucial information about test framework detection and reporting flags.
• Project Setup: The skill relies on project configuration files (e.g., vitest.config.*, pytest.ini) to detect frameworks; ensure these are present and correctly configured.
• Build Step Dependency: This skill does not handle building projects; use ln-781 for that purpose.
