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

      Specified by:

      Parameters:
      host - name of host
      See Also:
    • testStarted

      public void testStarted()

      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

    • followRedirects

      protected HTTPSampleResult followRedirects(HTTPSampleResult res, int frameDepth)
      Iteratively download the redirect targets of a redirect response.

      The returned result will contain one subsample for each request issued, including the original one that was passed in. It will be an HTTPSampleResult that should mostly look as if the final destination of the redirect chain had been obtained in a single shot.

      Parameters:
      res - result of the initial request - must be a redirect response
      frameDepth - Depth of this target in the frame structure. Used only to prevent infinite recursion.
      Returns:
      "Container" result with one subsample per request issued
    • resultProcessing

      protected HTTPSampleResult resultProcessing(boolean pAreFollowingRedirect, int frameDepth, HTTPSampleResult pRes)
      Follow redirects and download page resources if appropriate. this works, but the container stuff here is what's doing it. followRedirects() is actually doing the work to make sure we have only one container to make this work more naturally, I think this method - sample() - needs to take an HTTPSamplerResult container parameter instead of a boolean:areFollowingRedirect.
      Parameters:
      pAreFollowingRedirect - flag whether we are getting a redirect target
      frameDepth - Depth of this target in the frame structure. Used only to prevent infinite recursion.
      pRes - sample result to process
      Returns:
      the sample result
