Yes. You can set the parameter
TimeBetweenTestSuitesExecution to whatever delay you want to have. To change this parameter, go to the library references and select TcUnit, then go to
TimeBetweenTestSuitesExecution. Default this parameter is set to
T#0S (zero seconds, i.e. no delay). For example, in the below screenshot this is changed to 5 seconds.
Required TcUnit version: 1.2 or later
