perl A Perl script uses the Test::WWW::Selenium module to run Selenium tests in parallel using the Thread::Pool::Simple module. The tests are first set up with a Selenium driver, and then run in parallel using the thread pool. This approach significantly reduces the test execution time compared to running tests sequentially. The script is also easily convertible to work with Sauce OnDemand by modifying the settings and adding a job name attribute to the Selenium driver.
