Advanced automated API testing - cURL, Postman & Python requests

This training helps you become a test automation engineer.

In our current interconnected world, systems are no longer monolithic. Modern service oriented application (SOA) architecture requires integration of pre-built sub-systems through microservices as part of solution building. As a modern tester, you need basic and automated application programming interface (API) testing knowledge and practice as part of your testing toolset.

After establishing the theoretical API basics, the course will immediately become hands-on to learn how to interact with APIs through cURL. Using the GUI of the popular and widely used Postman application, you will learn firsthand how to build more complex requests easily. These requests can then be used as a basis for more advanced test scripts using Python's request library.

You will take test scripting to a more advanced level by using the Behave framework, a Cucumber implementation in Python. The use of the widely spread Python programming language will give you full control over your tests, Behave makes managing them child's play.

During the course we are not only focusing purely on technical implementation but also on common and best practices on how to set-up your API test framework. Various exercises based on real-life examples will help you better understand the concepts and bring them into practice.

At the end of this course, you will be able to:

  • have insight how modern API's are built;
  • have a good understanding of HTTP protocol;
  • access API's using cURL and Postman;
  • create test scripts using Python;
  • have practical experience setting up a framework based on Behave.


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please let us know.
