Running testingcases from script

You can use TestExecute to run some or all of your tests in one pass from the command line

If you aren't leveraging CI/CD pipelines you can always use Marsha_R approach and use command line to run your tests with TestExecute or TestComplete. An easy way to automate your test runs would be to create a batch file using your own version of the code below, then set up a Windows Scheduled task to run the batch file.

"C:\Program Files (x86)\SmartBear\TestComplete 15\x64\Bin\TestComplete.exe" "C:\<your project path here>.mds" /r /p:<project name here> /u:<test unit name here> /rt:<test name here> /exit /SilentMode

I would add that TestExecute only comes with the Desktop license of TestComplete or as a stand-alone license, if you don't have the Desktop version you get the TestExecuteLite version, which really isn't great for anything - [see why here] - but you can always reference TestComplete instead if you don't have the full TestExecute runner.
