Description

This course is about "API testing". Both manual and automated API testing with Postman. And this course is for beginners and for people who want to recall basic knowledge and API testing skills. API testing is a complex topic, and I will try to make it as easy as possible, but it still will be a complex topic. It is also a controversial topic. No matter how many people you ask how to test the API, they all have their own approach and their own way of testing. In some things they are right, in some things they are wrong. And so, getting acquainted with different approaches and ways, we create our own unique approach and way. Which also is right, and wrong. In this course, you will find my way of sailing in this restless, boundless, and stormy ocean of API testing. I hope it will help you find your own way.

In this course, you will have 5 baby steps.

1st - learn theory.

2nd - learn what manual API testing looks like. I will imitate the user stories and real project experience so it will be easier to understand.

3rd - improve your API testing skills with proper use of Postman features.

4th - automated API testing with Postman.

5th - examples of manual and automated API testing.

Happy sailing!

Who this course is for:

  • Manual testers who need to learn how to test APIs ASAP
  • People who can't imagine their life without REST APIs
  • People who love coffee
