In the Parallel Options dialog, you can configure the settings that control running tests in parallel from TestExecute.
To call the dialog, right-click the TestExecute icon () in the notification area (tray), select Options from the ensuing context menu, and then select Engines > Packer from the tree displayed on the left side of the resulting Options dialog.
You can change the following options:
Parallel test count - Specifies the maximum number of tests to execute simultaneously during a single test run. 0 is the default value and sets an unlimited number of tests.
Wait for a permission to run in remote environments - If you run your tests in remote environments provided by CrossBrowserTesting, this option specifies for how many seconds TestComplete will wait for it to allow the test to run.
