What is Coverage Booster?
Coverage Booster is a powerful utility within the Openclaw Skills ecosystem designed to bridge the gap between development speed and code quality. It eliminates the manual effort of writing boilerplate test code by scanning your project for untested functions, branches, and logic paths. By integrating this into your workflow, you can ensure high-quality standards across your codebase without the overhead of manual test authoring.
This tool is specifically engineered to handle the complexities of modern JavaScript and TypeScript environments. Whether you are dealing with a legacy codebase or a fast-moving new project, utilizing Openclaw Skills like this one ensures that your test suites remain robust and comprehensive without slowing down your delivery pipeline.
Coverage Booster Use Cases
- Legacy codebases with minimal existing test coverage needing rapid improvement.
- Meeting strict coverage thresholds for release gates or CI/CD pipelines.
- Identifying and testing complex business logic or edge cases that are often overlooked.
- Scaling test suites quickly after major feature updates within Openclaw Skills projects.
How Coverage Booster Works
- The tool performs a deep scan of the specified source directory to map functions, branches, and conditional logic.
- It compares the source map against existing test files to pinpoint exactly where coverage is missing.
- Using AI-driven analysis, it prioritizes uncovered code based on cyclomatic complexity to target the riskiest areas first.
- It generates Jest or Vitest compatible test files tailored to the specific code paths identified in the scan.
- The resulting tests are outputted as ready-to-run files that can be reviewed and integrated immediately into your Openclaw Skills workflow.
Coverage Booster Setup
To use this tool as part of your Openclaw Skills toolkit, ensure you have Node.js 18+ installed. No manual installation is required as it runs directly via npx.
# Scan and boost coverage for your entire src directory
npx ai-coverage-boost src/

Coverage Booster Data Schema & Taxonomy
The tool processes your source files and generates structured test outputs. It follows a specific taxonomy to ensure compatibility with modern JavaScript environments commonly used with Openclaw Skills.
| Item | Description |
|---|---|
| Source Files | Scans .ts, .js, .tsx, and .jsx files in the target directory |
| Test Frameworks | Generates code compatible with Jest and Vitest standards |
| Prioritization | Complexity-weighted queue ensures high-risk logic is tested first |
| Output Structure | New test files are generated following standard naming conventions (e.g., *.test.ts) |
Coverage Booster Advanced Features
- Automated branch and error handler detection for comprehensive coverage reaching deep into conditional logic.
- Intelligent prioritization of high-risk code paths to maximize the ROI of your testing efforts.
- Support for complex glob patterns to target specific modules, directories, or file types.
- Zero-config execution designed to work seamlessly within any Openclaw Skills automation pipeline.
