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

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

#!/bin/bash
set -e

# Configuration
COLLECTION="./collection.json"
ENVIRONMENT="./environment.json"
REPORT_DIR="./reports"
TIMESTAMP=$(date +"%Y%m%d_%H%M%S")

# Ensure report directory exists
mkdir -p "$REPORT_DIR"

echo "Running Newman collection: $COLLECTION"

newman run "$COLLECTION" \
  --environment "$ENVIRONMENT" \
  --reporters cli,htmlextra,junit \
  --reporter-htmlextra-export "$REPORT_DIR/report_$TIMESTAMP.html" \
  --reporter-junit-export "$REPORT_DIR/junit_$TIMESTAMP.xml" \
  --timeout-request 10000 \
  --bail

EXIT_CODE=$?

if [ $EXIT_CODE -eq 0 ]; then
  echo "✅ All tests passed."
else
  echo "❌ Tests failed. Check report: $REPORT_DIR/report_$TIMESTAMP.html"
  exit $EXIT_CODE
