docs: <p>
  Initiates a stop request for the current test run. AWS Device Farm will immediately stop the run on devices where
  tests have not started executing, and you will not be billed for these devices. On devices where tests have
  started executing, Setup Suite and Teardown Suite tests will run to completion before stopping execution on those
  devices. You will be billed for Setup, Teardown, and any tests that were in progress or already completed.
