    - #### testStarted

          public void testStarted()

      Description copied from interface: `TestStateListener`

      Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testStarted` in interface `TestStateListener`
      See Also:
        `TestStateListener.testStarted()`

    - #### testStarted

          public void testStarted(String host)

      Description copied from interface: `TestStateListener`

      Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testStarted` in interface `TestStateListener`
      Parameters:
        `host` - name of host
      See Also:
        `TestStateListener.testStarted(java.lang.String)`

    - #### testEnded

          public void testEnded()

      Description copied from interface: `TestStateListener`

      Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testEnded` in interface `TestStateListener`
      See Also:
        `TestStateListener.testEnded()`

    - #### testEnded

          public void testEnded(String host)

      Description copied from interface: `TestStateListener`

      Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

      N.B. testStarted() and testEnded() are called from different threads.

      Specified by:
        `testEnded` in interface `TestStateListener`
      Parameters:
        `host` - name of host
      See Also:
        `TestStateListener.testEnded(java.lang.String)`
