Basic API Test Automation Using Postman

Putting It All Together

Basic API automation in Postman combines several features covered earlier: organizing requests into a Collection, parameterizing them with Environment variables, writing pm.test() assertions in each request, and running the whole suite with the Collection Runner.

A Simple Workflow

• Build and save each request needed for a test scenario inside a Collection.
• Add assertions in the Tests tab to check status codes and key response values.
• Parameterize URLs, headers, and body values using Environment variables.
• Run the Collection with the Collection Runner (or the Newman CLI for CI/CD) to get a pass/fail report.

Next Steps

As suites grow, teams often graduate from Postman-based automation to a code-based framework like Rest Assured for more advanced logic, reporting, and CI/CD integration.
