(Note: this is a desktop app but can also be installed from the command line for future virtual machine use).Once this is up and running we can download our container.First thing we need to do is install Docker Desktop for our respective OS (Mac or Windows).In this exercise we will download a single (standalone) Chrome browser with ChromeDriver already configured. We can also run our tests on devices that don’t have computer graphics like AWS EC2 instances (virtual machines), and CI/CD services like TravisCI and CircleCI to name a few.ĭocker Desktop and Container Installation: The upside is we can manage the installation and running of the browsers and drivers in an easier way. The downside is one customers don’t use your application in a headless state and two these tests are harder to debug. ![]() Instead you get a command line to run and debug your tests. In the context running a Selenium test headlessly in Chrome, it means Chrome launches and runs the test in the browser but you don’t see it because there is no GUI. ![]() …Except now we’ll be running your tests headlessly which customers don’t do. Simply download and run a single Docker container with both the the browser and the driver pre-installed. ![]() However that’s all changed if we instead use containers. ![]() Some of my most popular posts are about installing these drivers. It used to be that in order to get your Selenium tests running on a given machine you had to install each individual browser and then the browser drivers (for instance ChromeDriver for Chrome).
