Automate Your API Tests with Postman

Integrate automated testing into your CI/CD pipeline to ensure that any code changes won't break the API in production.

Validate Your Schema

Use the schema as a single source of truth to write tests against your API.

Broad Schema Support

Use the API specification format of your choice in Postman. Write, edit, or import schema formats including RAML, WADL, OpenAPI, and GraphQL. Then generate collections directly from the schema.

Edit and Version Schema

Track and communicate changes to the API design by editing and versioning schemas in one central location. No more having to switch between tools.

Maintain a Single Source of Truth

Rely on your schema as a source of truth for API design and development and ensure all teams are working toward the same goal.

Write Test Suites

Write test suites so that teams can debug together.

Create test suites

Write custom test suites in JavaScript in the Postman Sandbox for each request. Use Postman's PM API to write even more powerful tests that allow you to assert a set of predefined rules for testing to enable better and cleaner tests.

Parameterize requests

Avoid running the same test by testing multiple instances of the same request with parameterization. Insert variables in any part of the request and Postman will replace them with values from a data file or environment variable.

Run the tests and debug

Use the collection runner in the Postman app to test a collection and view the results in real time. Or use Newman to view test results in the terminal. For any issues, debug in Postman's Console Log. Built specifically for API development, it records the raw request and response, certificates, and error logs from scripts.

Integrate Testing into Your CI/CD Pipeline

Add a test suite as a build step to ensure your APIs are compatible.

Streamline Development and Testing with a CI/CD Pipeline

Reuse your test suites to create a CI/CD pipeline that tests at every push. You can seamlessly integrate your Postman instance with Jenkins to create your own pipeline or add it to your existing pipeline as a build step.

Postman Scales Up With You

Create more robust and bug-resistant programs by increasing test coverage and frequency. Postman and Newman, our command line tool, allow you to easily set up your own automated tests.

Easily Manage Your Testing Sequences

Aggregate your tests into a single automated test sequence. Run and manage your test workflow from
