Sunday, October 2, 2022 - 8:30am to Monday, October 3, 2022 - 5:00pm

Python® for Testers

  • Explore examples covering topics such as generating test data, monitoring system under test, compressing and sending test data
  • Gain a solid understanding of the Python language, its philosophy, and the code syntax
  • Get a broad introduction to the vast standard library that Python comes installed with
  • What is Pythonic code, good practices and common pitfalls to avoid
  • Learn how to install third party Python libraries to extend the power of the language
  • Understand how to control external processes
  • Get started with performance measurements
  • Learn how transfer results to remote computers

Learn by Doing
This is a course for testers who are frustrated by the laborious and manual work that makes up day-to-day test work, anyone who has tried or wants to try scripting and programming in order to help them focus more on the sapient test activities and let the computer do the repetitive work.

During the course we will work with a strong focus on practical knowledge and learning by doing with much hands-on coding so that attendees can work independently with Python after the course. A large amount of exercises are built to give the opportunity to build simple but powerful tools using Python, which gives a deeper understanding of the opportunities that the language offers.

Why should I invest time in learning Python?
Because Python is powerful, efficient, and very fun to work in. You feel productive from the start and produce results with surprising speed. It is the perfect choice for a tester who wishes to use a programming language to assist them in their testing, and it's not a language that ends up standing in your way. Python is well established with over 20 years of history, included out of the box in most modern operating systems. It has a diverse, huge, and active community and ecosystem.

Who Should Attend
This course should be attended by engineers in a testing role or those seeking an introduction to programming concepts to develop their skills and learn more about the benefits and power of using Python for testing. The attendees are required to have basic computer knowledge and a genuine interest in learning about scripting and programming.

Participant Recommendations
This course assumes no prior programming knowledge or background and will work itself up from beginner to more advanced concepts. However, it will be helpful if you are familiar with one or more concepts such as how computers work, operating systems, networks, and how concepts such as file systems, files and folders work. In other words, a good technical knowledge as a tester will help you greatly in this class. Any prior experience writing scripts, programming, and using some sort of Unix system (Unix, Solaris, Mac, etc) and a terminal will help as well.

None of the above are hard requirements, but please be aware this is a very hands-on class with a rapid pace, and the less prior "general IT-knowledge" you may have will make it more challenging, albeit not impossible by any means. If you are looking for a class to sit back and relax and listen to only, then this class is not for you. You will be working very hands-on from the start and a great learning experience is guaranteed by writing the code and solving the problems posed by yourself.

Laptop Required
Attendees are required to bring their own laptop to be able to complete the exercises. Please ensure your computer is capable of the following:

  • Download a zip-file from the internet and extract it to the hard drive. If the class is taking place in a physical classroom then it is also acceptable to copy the zip-file from a USB-stick.
  • Run an OS with a file system that supports larger than 4Gb files (i.e not FAT32 on Windows)
  • Install and run VirtualBox. (Learn more at
  • Support VT-x/AMX-V hardware acceleration in the BIOS, ie run a virtual machine through VirtualBox.

The requirements above will be satisfied for the majority of computers. Please note if you have an older model computer, we highly recommend double checking that your computer is capable of the above requirements. Additionally, if your employer has strict security restrictions in place, please double check that you able to install software, access external USB sticks, etc. VirtualBox 5.1 or later.

Kristoffer Nordström is a test developer who has worked with telecommunications systems, distributed compilers, cloud technology, smartphone OS development, embedded systems, and much more. As a testing devotee and a member of the context-driven test community, with his own company Kristoffer consults and teaches the course Python for Testers because he believes in tools-assisted sapient testing. Over the years he has seen the immense value of testers learning how to distill large amounts of information into the so-called “big picture,” and he advocates for learning the soft skills necessary to collaborate with the people making up the organization. Apart from being an avid software tester, Kristoffer is also a sci-fi reader, lamp maker, and craftsman.
