Postman API Testing

Automate API testing in CI by importing Postman collections and environment files, then executing them with Newman to validate microservices across development stages automatically.

Managing API tests across multiple environments involves using separate environment files for dev, staging, and production, allowing the same Postman collections to execute reliably against different configurations.

Pre-request scripts execute JavaScript before an API call to set parameters, while test scripts validate responses, headers, and status codes after the request completes within Postman collections.

Run Postman API tests without the GUI by using Newman to execute collections and environment files directly from the command line, enabling seamless integration into CI pipelines.

JavaScript is required to write pre-request scripts and test assertions within Postman collections, enabling dynamic variable handling and response validation for your API testing workflows.

Postman collections function as living API documentation by storing executable test scripts alongside endpoint definitions, ensuring your API tests and documentation remain synchronized across microservices.
