VUH only
VUH can be used for on-premise tests on a fine-grained per-test consumption when used in combination with the Tricentis Edition (shared license).
When it comes to testing using the NeoLoad Cloud Platform, VUH may be used to run a Cloud test by selecting the Using VUH only, with Cloud sessions option in the License General settings.
In that case:
NeoLoad can run Cloud tests only.
NeoLoad starts a Cloud session that can be used for several tests.
The Cloud session is charged with VUH per full hour. Any hour begun is due in full.
VUH are consumed on the entire number of Virtual Users required. VUH cannot be combined with the license VUs.
Caution: The Using VUH only, with Cloud Sessions option can not be used to execute tests designed with RealBrowser.
The alternative for Cloud tests is to use a license in combination with Cloud credits. See Test from the Cloud.
