    • LoadTest

      protected LoadTest(String url, String apiKey)
      Creates a new instance of the load test.
      Parameters:
      url - The URL of the task app (without trailing slash!).
      apiKey - The api key to use for the requests.

    • run

      public void run(int totalAmountOfRequests, int threadCount, double requestFactor, int maxInitialSleep, int maxPauseBetweenRequestsInMs)
      Runs the load test.
      Parameters:
      totalAmountOfRequests - The total amount of requests to submit.
      threadCount - The amount of threads to use.
      requestFactor - The factor to use for the calculation of the minimum and maximum amount of requests per thread (min = avg_amount_of_requests - (avg_amount_of_requests * factor)), (min = avg_amount_of_requests + (avg_amount_of_requests * factor)).
      maxInitialSleep - The maximum initial sleep time in ms. The initial sleep time will be a random number between 0 and maxInitialSleep.
      maxPauseBetweenRequestsInMs - The maximum pause between requests in ms. The pause between requests will be a random number between 100 and maxPauseBetweenRequestsInMs.

    • createThreads

      protected final List<SubmissionThread> createThreads(int totalAmountOfRequests, int threadCount, double requestFactor, int maxInitialSleep, int maxPauseBetweenRequestsInMs)
      Creates the threads for the load test.

      Randomly assigns the initial sleep time and the pause between requests as well as the total amount of requests. The sum of the amount of requests of all threads will be equal to the total amount of requests.

      Parameters:
      totalAmountOfRequests - The total amount of requests to submit.
      threadCount - The amount of threads to use.
      requestFactor - The factor to use for the calculation of the minimum and maximum amount of requests per thread (min = avg_amount_of_requests - (avg_amount_of_requests * factor)), (min = avg_amount_of_requests + (avg_amount_of_requests * factor)).
      maxInitialSleep - The maximum initial sleep time in ms. The initial sleep time will be a random number between 0 and maxInitialSleep.
      maxPauseBetweenRequestsInMs - The maximum pause between requests in ms. The pause between requests will be a random number between 100 and maxPauseBetweenRequestsInMs.
      Returns:
      The threads.

    • createThread

      protected abstract SubmissionThread createThread(String name, String url, String apiKey, int initialSleep, int totalAmountOfRequests, int pauseBetweenRequestsInMs)
      Creates a new thread for the load test.
      Parameters:
      name - The name of the thread. This is used for logging.
      url - The URL of the task app. This should not contain a trailing slash.
      apiKey - The API key to use for the requests.
      initialSleep - The initial sleep time in milliseconds.
      totalAmountOfRequests - The total amount of requests to submit.
      pauseBetweenRequestsInMs - The pause between requests in milliseconds.
      Returns:
      The thread.
