How to review Postman test results
Blog post from Postman
Postman is a popular tool for API testing, allowing users to write tests to ensure APIs function as expected, verify integrations, and confirm that changes haven't broken existing features. Tests are written in JavaScript using the pm.test() method, which includes a test name and specifications for assertions using a Chai.js BDD syntax. Test results indicate pass or fail status, and examining assertion error messages helps identify issues. When a test fails, it may require updates from either the API producer or consumer to align expectations, serving as a communication tool about API behavior. To improve test readability, users are encouraged to group related assertions, use descriptive test names, and add console statements for clarity. The article emphasizes ensuring tests can fail to validate their robustness and suggests exercises for users to practice intermediate techniques.
