There is a setting "Default TimeoutHint" in the CTT, that is currently set to 20,000 ms.
When using the async publish mechanism, the CTT also uses this setting for the TimeoutHint in the PublishRequests.
This is fine for most of the test scenarios, but there are some test cases, that requires the use of multiple parallel PublishRequests.
For example Publish Min 02 / 003 requires 2 parallel PublishRequests while using a PublishingInterval of 10 seconds. So there is a very small time frame in that this test would be passed, but most of the time, the second PublishRequest will be timed out before the server can use it for a response.
For such cases, it should be possible to specify a value for the TimeoutHint that should be used in the PublishRequest when starting the async publish from a test script.
