Containers are de facto a standard way to distribute services and software. It's convenient to have preconfigured environment that can be activated on any machine that has a container engine such as docker or podman. UI testing with Selenium requires certain environment including browsers, X server and a window manager. It would be nice to have all of these packed into a one container image.

Web UI testing is a tricky thing in many aspects. They requires many dependencies, they are slow and they are often flaky. In this post I would like to share my web UI testing experience on an example of one python library.

When you test your web application with Selenium there is a one fundamental problem. Due to dynamic nature of modern web pages you cannot interact with elements on the web page immediately after loading. What can we do with that?

As a quality engineer I responsible for testing various parts of a product. One of such part can be the web UI. But before your first UI test will be executed you will need to configure a lot of things. It might be a non-trivial task. Kubernetes can be quite helpful here and be actual "one ring to rule them all".
