Does it automatically fix my code?

When tests fail, the skill analyzes whether the bug is in the source code or the test itself and applies the necessary fixes to achieve a 100% pass rate.

What kind of reports does the skill generate?

It provides a structured execution report detailing the total number of tests, pass/fail results, code coverage percentages, and a summary of every modification made.

Which programming languages and frameworks are supported?

The skill supports a wide range of ecosystems including JavaScript (Vitest/Jest), Python (Pytest), Go, Rust, and Java, automatically adapting to the project's specific requirements.

Can this skill set up testing for a project that has none?

Yes, if no test infrastructure is detected, the skill will install necessary dependencies and create configuration files for the most appropriate modern testing framework.

How does it handle complex test environments?

It checks configuration files like package.json or pyproject.toml to respect existing scripts and environments, ensuring it uses the project's preferred execution commands.

Security & Testing

Automates test execution, failure diagnosis, and infrastructure setup to ensure 100% test pass rates across multiple languages and frameworks.

About

The Run the Tests skill transforms Claude into a specialized test execution and fixing agent. It automatically detects project types, identifies existing test runners, and executes the full suite to find regressions or failures. If a project lacks testing infrastructure, it proactively sets up modern, best-in-class environments like Vitest for JavaScript or Pytest for Python. The skill goes beyond simple reporting by diagnosing root causes—distinguishing between implementation bugs and broken assertions—and iteratively applying fixes until the entire codebase is healthy and passing.

Key Features

Intelligent diagnosis and automatic fixing of implementation bugs and test assertions.
Detailed execution reporting including pass/fail counts, coverage metrics, and change summaries.
Proactive setup of industry-standard testing infrastructure if no framework is detected.
3 GitHub stars
Comprehensive support for JavaScript, TypeScript, Python, Go, Rust, and Java.
Automatic detection of project language, framework, and existing test configurations.

Use Cases

Ensuring code quality by running and fixing all tests before completing a task or pull request.
Bootstrapping testing environments in new or legacy projects that lack proper infrastructure.
Automating the iterative process of debugging complex test failures and edge cases.
