Testing With Postman: Newman

I build automation frameworks — not just tests. Over 10 years I've designed and shipped production testing platforms across payment, insurance, and healthcare domains. My instinct is always toward architecture: clean abstractions, maintainable patterns, and systems that don't fall apart when the product scales. What I'm working on now: - A Claude/Playwright agent framework that generates test cases directly from Jira tickets - Concurrency and race-condition coverage for financial transactions - A modular Playwright/JavaScript platform covering UI and 20+ API service integrations with 100+ JSON schema validators I've built production automation in Playwright, Geb/Spock, Rest-Assured, and Selenium across payment, insurance, and healthcare domains. When a stack isn't working, I replace it. When a pattern is wrong, I fix it. If the automation problem is interesting, I'm probably already thinking about it.

Next is to setup a DevOps job you can go here to learn how to do that. For this section we will focus on the Execute shell and newman. With this I suggest going through Postman's official documentation found here. This takes your postman game and ups it to be able to be leveraged with Continuous Integration.

There are 2 ways to run this and one is extraction your collections json and running newman using that file. The other takes a bit more setup but uses Postman's API and when you updated the test they update in the cloud.

I would suggest for reports that you check out this HTML Reporter. It is created by a employee of postman and is by far the best HTML report out there in my opinion.
