Block 1 – Comprehensive Summary for Podcast (English) 🔹 What Is Postman & Why Use It? Postman is a leading API testing tool for sending HTTP requests and validating responses TutorialsPoint +1 apidog +1 . Supports functional and automated testing workflows, and integrates seamlessly with CI/CD pipelines using Newman Medium +2 Tools QA +2 Postman +2 . 🔹 Core HTTP Methods Used to perform operations on APIs: GET: Retrieve resources POST: Create a resource (e.g., money transfer via Zelle) PUT / PATCH: Update existing data DELETE: Remove data Postman Community +14 Testsigma +14 apidog +14 Global App Testing 🔹 Key HTTP Status Codes Essential codes to know: 200 OK: Request succeeded 201 Created: Resource created 400 Bad Request: Invalid input 401 Unauthorized: Authentication or permissions issue 403 Forbidden, 404 Not Found, 500 Server Error Code Intelligence +2 Speakeasy +2 arXiv +2 Postman Docs +11 Testsigma +11 Tools QA +11 Code Intelligence +4 Global App Testing +4 apidog +4 🔹 Writing Test Scripts in Postman Automate response validation using JavaScript: js Copiar Editar pm.test("Status code is 200", () => { pm.response.to.have.status(200); }); Validate status codes, response body, headers, etc. Executed automatically within Postman when running collections apidog +4 Reddit +4 Ministry of Testing +4 apidog +2 Code Intelligence +2 YouTube +2 Wikipedia +15 GeeksforGeeks +15 Tools QA +15 🔹 Collections, Environments & Variables Collections group related requests together (e.g. Zelle: create, status, history) Environments manage variables like {{base_url}}, {{token}} per environment (QA, Prod) Variables reduce duplication and increase flexibility Testsigma GeeksforGeeks 🔹 Automating with Newman & CI/CD Integration Export Postman collections (.json) and environments Execute via CLI: bash Copiar Editar newman run collection.json -e env.json Integrate into tools like Jenkins/GitLab CI for automated regression testing Tools QA Postman Docs 🔹 Designing Robust API Test Cases Begin by understanding API documentation: endpoints, parameters, auth, limits Global App Testing GeeksforGeeks Define test scenarios: positive, negative, and edge cases (e.g., boundary values, empty inputs) Postman Community +3 Global App Testing +3 Wikipedia +3 Structure each test case: ID Description Pre-conditions Test steps (method & endpoint) Input data Expected results (status + body/schema) Post-conditions Ministry of Testing +12 Global App Testing +12 Postman +12 Prioritize scenarios by risk and critical functionality; keep test cases updated as API evolves GoReplay Testsigma 🔹 Postman Best Practices Shift-left testing: Start API testing early in development to catch defects sooner Postman +1 Medium +1 Validate error handling and edge cases Keep tests maintainable and up-to-date with API changes GoReplay Code Intelligence
