I was watching you video 'Execute TestNG tests on multiple browsers in parallel'. But failed at the first step.
When I typed the folowing command:
java -jar selenium-server-standalone-2.45.0.jar -role hub
I got error message:
Exception in thread "main" org.openqa.grid.common.exception.GridConfigurationException: The role specified :-hub doesn't
match a recognized role for grid.
Could you explain to me what I did wrong? Thanks so much in advance.
