Automate Your API Tests with Postman
Validate Your Schema
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
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
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
- The Postman app,
- Postman monitoring, or
- from the command line with Newman.
