To ensure a load test accuracy and prevent client-side errors from having an impact on the test results, the test device must be validated.

When the device tasks are set, LoadView executes the single-user test run considering system and user behavior delays for the device. Also, the single-session duration (Session Duration) and resources required to execute the device tasks are calculated upon validation.

You can find validation results status on the Test Scenario page,  in the Device section. 

If any validation errors were detected, click View Details and check the Errors tab of the Performance Report. Fix the errors if possible before the test starts.
