Running tests

In separate terminals run:

1. Selenium Hub (which accepts requests from test framework):

   java -jar selenium-server-standalone-2.53.0.jar -role hub -timeout 300
   

2. Selenium Node (which will run the browsers) together with virtual X server. Following allows to run 30 chrome browsers:

   DISPLAY=:1 xvfb-run java -jar selenium-server-standalone-2.53.0.jar -role node -hub http://localhost:4444/grid/register -browser browserName=chrome,maxInstances=30 -maxSession 30
