postman2jmx
Converts Postman collections (V2+) to JMeter JMX files for performance testing.
What is postman2jmx?
postman2jmx is a Java command-line tool that converts Postman collection files (V2 format) into JMeter JMX files. It solves the problem of manually recreating API tests in JMeter by automating the conversion process, saving time for developers and performance testers.
Performance testers, QA engineers, and developers who use Postman for API development and need to run load tests with JMeter.
It provides a free, open-source alternative to manual conversion or commercial tools, with a simple CLI that integrates easily into existing workflows and supports modern Postman collections.
