There are a few configurable options available for Live Unit Testing, which you can modify if you want to. To do so, navigate to Options from the Tools menu. Now, from the left pane, select Live Unit Testing | General.

In the right pane, there are a couple of settings available, as shown in the following screenshot:

The first option enables you to control whether the Live Unit Testing runs automatically on solution load. The second option enables you to control whether the Live Unit Testing will pause while building and/or debugging is in progress. The third option will let you pause the automatic test execution when the battery power falls below a threshold value. By default, it is set to 30%.

In this screen, you can also control the Testcase Timeout in milliseconds, which is 30000 ms (30 secs) by default. You can also set the number of test processes that the Live Unit Testing will create.

Aside from these, you can set the logging level of Live Unit Testing. When it is set to None, there won't be any automatic logging performed; when it is set to Error or Info, only error messages or informational messages will get logged based on the selection. Set it to Verbose, if you want to log every detail. The default logging level is Info.
