Newman Runner

This skill provides tools to run Newman (Postman CLI) tests and analyze the results for API testing and validation.

Instructions

Running Newman Tests

1. Verify Newman Installation

   • Check if Newman is installed: which newman
   • If not installed, install with: npm install -g newman

2. Run Collection

   • Use script: scripts/run-newman.sh <collection.json>
   • Or manually: newman run collection.json --reporters cli,json --reporter-json-export output.json

3. Analyze Results

   • Parse JSON output with: scripts/analyze-newman-results.py output.json
   • Extract: Pass/fail status, response times, error messages, assertions

Available Scripts

• scripts/run-newman.sh - Run Newman with standard options
• scripts/analyze-newman-results.py - Parse Newman JSON output
• scripts/validate-collection.sh - Validate Postman collection structure

Examples

Example 1: Run API Tests

# Run Newman tests on Postman collection
./scripts/run-newman.sh my-api-tests.json

# Analyze results
./scripts/analyze-newman-results.py newman-results.json

Example 2: Validate Collection

# Check collection is valid before running
./scripts/validate-collection.sh my-collection.json

Requirements

• Newman installed globally: npm install -g newman
• Valid Postman collection JSON file
• Python 3.7+ for analysis scripts

Success Criteria

• ✅ Newman tests run successfully
• ✅ Results parsed and analyzed
• ✅ Pass/fail status clearly reported
• ✅ Error details extracted for failures
