+##### BlockingInvokeOneActionSimulation
+
+This simulation executes the same action with the same user over and over again.
+The aim of this test is, to test the throughput of the system, if all containers are always warm.
+
+The action that is invoked, writes one log line and returns a little json.
+
+The simulations creates the action in the beginning, invokes it as often as possible for 5 seconds, to warm all containers up and invokes it afterwards for the given amount of time.
+The warmup-phase will not be part of the assertions.
+
+To run the test, you can specify the amount of concurrent requests. Keep in mind, that the actions are invoked blocking and the system is limited to `AMOUNT_OF_INVOKERS * SLOTS_PER_INVOKER * NON_BLACKBOX_INVOKER_RATIO` concurrent actions/requests.
+
+Available environment variables:
+```
+OPENWHISK_HOST          (required)
+API_KEY                 (required, format: UUID:KEY)
+CONNECTIONS             (required)
+SECONDS                 (default: 10)
+REQUESTS_PER_SEC        (required)
+MIN_REQUESTS_PER_SEC    (default: REQUESTS_PER_SEC)
+```
