Load Test: The test has not started yet

by XDK 4. February 2014 14:06

Exception:

"The test has not started yet"

Explanation:

The test run result window just lists the name of the machine from which it ran, but it never opens the results and also Test run state remains pending. After I double click on the machine test item it just says "The Test has not started yet". Not able to view the result online during load test execution time. 

 

Solution:

The VS 2010 client version which I used to execute the load was SP1. But the test rig environment version was only VS 2010 RTM. 

1. Installed the SP1 on test controller and agents

2. Reconfigured the agents to controller again.
