Endless ST loops and their implications - Manual - AxUnit-ST - AxUnit ST documentation package - AxUnit-ST,

If your ST code contains an endless loop, and the endless loop is executed during testing, there are two ways to solve the problem and stop the test execution:

• Simply wait for 5 minutes. A test run will be aborted after this time has passed.
• If you use the CLI or the stop button does not stop the test execution:
  • Cancel the test in the CLI by pressing Control + C.
  • Open the task manager of your operating system.
  • In the background processes, search for the task tests.exe and abort it.

You will be able to execute your tests again.
