Description

Training Introduction:

The “API Testing with Postman: Automating RESTful Services” course is designed to equip participants with the skills and knowledge necessary to effectively test and automate RESTful APIs using Postman. Postman is a popular and user-friendly tool that simplifies the process of creating, managing, and executing API tests.

In this course, participants will learn how to use Postman to test API endpoints, automate test execution, and integrate API testing into their development workflows. The course covers the fundamentals of API testing, including creating and running tests, handling authentication, and using advanced features of Postman for comprehensive testing. By the end of the course, participants will be able to ensure the reliability and performance of APIs through effective testing strategies.

Prerequisites:

• Basic understanding of web services and APIs (RESTful services).
• Familiarity with HTTP methods and response codes.
• No prior experience with Postman is required, but some knowledge of general testing concepts is helpful.
