What This Skill Does

The Newman skill enables OpenClaw to act as a powerful API test runner by leveraging the Newman CLI, the official command-line engine for Postman. It allows users to execute complex Postman collections directly from the command line, facilitating automated API verification, regression testing, and CI/CD integration. This skill bridges the gap between Postman's GUI-based design and the need for repeatable, scriptable API testing environments. Whether you need to run individual collections, use data-driven files (CSV/JSON) for stress testing, or generate detailed reports in HTML, JSON, or JUnit formats for automated build pipelines, this skill provides a robust interface to handle these tasks efficiently.

Installation

To add the Newman skill to your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/1999azzar/newman

Ensure that you have Node.js and npm installed on your system, as Newman is a Node-based package. You can verify the installation by running newman --version after the installation process is complete.

Use Cases

• Continuous Integration: Integrate API test suites into Jenkins, GitHub Actions, or GitLab CI pipelines.
• Regression Testing: Ensure that new code changes do not break existing API endpoints by running comprehensive collections before deployment.
• Data-Driven Testing: Run the same collection against multiple sets of user data, such as different credentials or edge-case payload scenarios.
• Reporting: Generate documentation-ready HTML reports of API health to share with stakeholders or development teams.
• Security Audits: Automate the checking of response headers, status codes, and payload security compliance.

Example Prompts

1. "Run the user-auth collection with the production environment file and save the output as an HTML report."
2. "Execute the API test suite using data.csv to perform stress testing, and fail the process if any test encounters an error."
3. "Automate the Newman test for my collection.json file and generate a JUnit report for my CI/CD pipeline."

Tips & Limitations

• Security: Never commit sensitive credentials or API keys directly into your collection.json file. Always use environment files or system environment variables to inject sensitive data during runtime.
• Performance: For extremely large collections or high-frequency iterations, monitor your system memory, as Newman runs within the Node.js runtime.
• Debugging: Use the --verbose flag when a test fails unexpectedly; this provides deep insight into request headers, body content, and response payloads to help you pinpoint failures quickly.
• Compatibility: Always ensure your exported collections are in the v2.1 format for maximum compatibility with the latest Newman features.
