Newman CI/CD Integration Generator

Generate complete, copy-paste-ready CI/CD pipeline configs that install Newman and run Postman collections as part of automated builds.

---

What to Collect From the User

Before generating a config, determine:

1. CI platform — GitHub Actions, GitLab CI, Jenkins, Azure DevOps, CircleCI, Bitbucket?
2. Collection source — local file in repo, or Postman API URL?
3. Environment — local env file in repo, or env vars injected by CI secrets?
4. Reporters needed — JUnit XML (for CI test results panel), HTML report, or both?
5. Node.js version preference (default: 18)
6. Trigger — on every push, pull request, schedule, or after deploy?
7. Fail build on test failure? — almost always yes; confirm

Best Practices

Secrets — never hardcode credentials

Always inject sensitive values as CI environment variables/secrets:

• GitHub: Settings > Secrets and Variables > Actions
• GitLab: Settings > CI/CD > Variables
• Jenkins: Manage Jenkins > Credentials
• Azure DevOps: Pipelines > Variables

Reference in Newman via --env-var "KEY=$SECRET_NAME" or pre-set in the environment file.

Store collection and environment files in the repo

/
├── collections/
│   └── my-api.json
├── environments/
│   ├── staging.json
│   └── prod.json
└── results/         ← gitignored, created by Newman

Add results/ to .gitignore.

Always use if: always() / when: always

Ensure test result artifacts are published even when Newman exits with a failure code.

Exit codes

Newman exits with code 1 if any tests fail — this automatically fails the pipeline step. Use --bail if you want to stop on the first failure rather than running all tests.

---

How to Generate Configs

1. Confirm the CI platform and tailor the exact syntax
2. Use the correct secret/variable injection syntax for that platform
3. Include artifact publishing steps so test results appear in the CI UI
4. Add comments explaining secrets that need to be configured
5. Keep environment files in the repo (without secrets); inject sensitive values via CI vars

After Completing the Newman CICD output

Once the Newman CICD output is delivered, ask the user:

"Would you like me to generate Postman Test Cases for these commands? (yes/no)"

If the user says yes:

• Check if the postman-testcase-generator skill is available in the installed skills list
• If the skill is available:
  • Read and follow the instructions in the postman-testcase-generator skill
  • Use the CICD command output above as the input
• If the skill is NOT available:
  • Inform the user: "It looks like the postman-testcase-generator skill isn't installed. You can install it and re-run.

If the user says no:

• End the task here
