API Test Automation with Postman
This certification validates my knowledge of API testing using Postman. I learned how to work with REST APIs by sending different types of requests (GET, POST, PUT, DELETE), analyzing responses, and verifying status codes and data accuracy. The course also covered test case creation, error handling, and basic automation using Postman scripts to ensure API reliability and performance.
What I Learned
Postman Setup & Configuration
Installed and configured Postman for API testing, exploring the interface and workspace management features.
Collections & Environments
Imported and organized API collections and environments for structured, reusable test workflows.
HTTP Request Methods
Created and executed HTTP requests — GET, POST, PUT, DELETE — to interact with RESTful APIs effectively.
Response Validation
Validated API responses using status codes, headers, and body content to ensure correctness and reliability.
Test Automation with JavaScript
Implemented automated tests using JavaScript in Postman's test scripts to run assertions after each request.
Mock Servers
Created and used mock servers for testing APIs without requiring a live backend, enabling early-stage testing.
API Monitoring
Monitored APIs using Postman monitors for scheduled, automated testing to catch regressions over time.
Newman CLI
Used Newman CLI to run Postman collections from the command line, enabling CI/CD pipeline integration.
Dynamic Testing with Variables
Managed environments and variables for dynamic, data-driven testing across multiple test scenarios.
Error Handling & Edge Cases
Tested error handling and edge cases in APIs to ensure robust and resilient endpoint behavior.
Real-World API Workflows
Gained hands-on experience with real-world API testing workflows, bridging theory and practical application.
QA Best Practices
Applied QA mindset to API testing by structuring test suites, documenting results, and ensuring coverage.
