Set Test Execution Time Limit

In some automation scenarios it is necessary to limit a single test execution to a certain time frame. That is possible if the following approach is used. In an execution extension library is set timer that is re-set each time the new test starts. If the time expired before the timer is re-set - all processes related to test execution are killed. This will ensure if a test takes more than initially defined time interval to stop its execution and continue with the next test. Below is given sample execution extension library with time frame set to 5 minutes.
