About This Udemy Course

The following is the full official course description for Postman: The Complete Guide - REST API Testing as published on Udemy by instructor Valentin Despa. It covers the curriculum structure, teaching methodology, and topic scope for this Development course.

**Learn Postman with a Postman Supernova**. RESTful APIs (or simply REST API) are everywhere nowadays, but at the same time, they are getting more complex to get started with: different HTTP methods (GET, POST, PUT, PATCH, DELETE), headers, cookies, dealing with file uploads or authentication with API keys, tokens, OAuth and so much more. This is where the Postman App comes in! Postman allows you very quickly to create a request with the required HTTP method and parameters, submit the request and easily inspect the results. I have created this course for testing engineers as well as for software developers or other technical positions. Postman can help you during the development of your API, as well as after the API is completed, by running tests that make sure your API is still working as intended. In the first part of the course, we will start exploring the features of Postman and continue by writing API tests with the intention of integrating them into a CI server where the tests will run on a current basis. But this is not the normal course you take part in. Because your needs may be different and because I hate leaving you wondering what to do next, the second part of the course will include user questions and answers to problems that were not yet covered in the course or that are more specific and may not interest everybody. So let’s look at what you are going to learn: - HTTP request methods (GET, POST, PUT, PATCH, DELETE) - JSON format - Start with simple requests and advance toward more complex scenarios - Learn to deal with authentication/authorization mechanisms like Basic Auth, API Keys, or OAuth. - Start writing API tests - Organize tests in collections and share them with your team - Run API tests in Jenkins or any other CI server - You ask, I answer So after this course, you will know how to use Postman as a pro.
