Hi Jason, are you trying to run the tests against Selenium Grid?? what your selenium server host is in the TelluriumConfig file. I have not looked at the connector code for some time now. I know that com.thoughtworks.selenium.grid.tools.ThreadSafeSeleniumSessionStorage.session() is thread safe and if you are running the tests using Selenium Grid and the tests are going to get the selenium sessions from Selenium HUB then it would be easy to manage the parallel test execution.
