postman-newman-automation

postman-newman-automation is a skill for Claude Code, Codex from LambdaTest/agent-skills. It costs 156 tokens per session (2,067 once invoked), scanned A, original, MIT.

A guide for using Newman, the command-line runner for Postman collections, which are saved groups of API requests and checks.

In plain words
What is it for?
It helps create Newman commands, shell scripts, and Jenkins pipeline files for local or automated runs, including reports, test data, environments, and failure handling.
Why use it?
It removes the need to run Postman collections manually when testing an API repeatedly or as part of a build process.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

postman-newman-automation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Postman Newman Automation

Generates Newman CLI commands, shell scripts, and Jenkins pipeline configs for running Postman collections in automated environments.


Newman Basics

Newman is Postman's CLI runner. Install with:

npm install -g newman
# Optional HTML reporter:
npm install -g newman-reporter-htmlextra

Core Command Structure

newman run <collection> \
  --environment <env-file> \
  --globals <globals-file> \
  --iteration-count <n> \
  --iteration-data <csv-or-json> \
  --reporters <reporter-list> \
  --reporter-htmlextra-export <output.html> \
  --reporter-junit-export <results.xml> \
  --timeout-request <ms> \
  --delay-request <ms> \
  --bail \
  --color on

Step 1 — Gather Requirements

Ask or infer from context:

Parameter Question
Collection source File path, URL, or Postman API UID?
Environment File path or inline variables?
Reporter(s) CLI only, HTML report, JUnit XML?
Fail behavior Stop on first failure (--bail) or run all?
Iterations Single run or data-driven (CSV/JSON)?
Target Local shell, Jenkins, or both?

Step 2 — Generate Newman Command

Basic run (local)

newman run collection.json \
  --environment environment.json \
  --reporters cli,htmlextra \
  --reporter-htmlextra-export reports/report.html \
  --bail

Run from Postman API (by UID)

newman run "https://api.getpostman.com/collections/<UID>?apikey={{POSTMAN_API_KEY}}" \
  --environment environment.json \
  --reporters cli,junit \
  --reporter-junit-export results/junit.xml

Data-driven run (CSV)

newman run collection.json \
  --iteration-data test-data.csv \
  --iteration-count 5 \
  --reporters cli,htmlextra \
  --reporter-htmlextra-export reports/data-driven-report.html

With environment variable overrides (no file needed)

newman run collection.json \
  --env-var "base_url=https://staging.api.example.com" \
  --env-var "token=abc123" \
  --reporters cli

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
