Before running tests on a specific browser, it is necessary either to install it into the system, e.g. sudo app install firefox or install a portable browser, e.g. npm install chromium.

In the latter case, you need to ensure that the installation is correct, i.e. the browser's executable exists and all required dependencies are installed. You can use the following command to check the executable's dependencies: ldd node_modules/chromium/lib/chromium/chrome-linux/chrome. Note that if you install the browser into the system with the system package manager, it will install all required dependencies automatically.
