Introduction to API Testing is a practical training program designed to help participants understand how APIs work and how to effectively test their functionality, reliability, and performance. The course covers essential API testing concepts, REST APIs, request and response validation, HTTP methods, status codes, authentication, test scenarios, and troubleshooting techniques. Participants will gain hands-on experience creating and executing API tests, identifying defects, validating data, and applying effective testing practices to ensure APIs work correctly and reliably within modern software applications.
Course Overview:
This course is designed to cover all aspects of API Testing & Postman tool and also to provide users with the knowledge required to work with Postman tool at a professional level. This course addresses planning and performing API tests, developing the pre-test & post-test scripts using Postman, executing the API tests and generating HTML reports using different tools like Newman.
The course covers real-world best practices for effective use of Postman tool for API testing with practical examples demonstrated. Postman is a popular automation tool for API testing. Postman offers features that simplify each step of testing an API.
