Some Tosca Test Case Script statements, such as "TBox Take Screenshot", require a Directory specification for Tosca to store the image file. In a multiuser, distributed Tosca environment, this directory must be a file share that all Tosca machines can reach. When setup correctly, an image captured during a run that executes on one machine, can be seen in a report generated by another machine.

Create a common file share that all machines can reach and that all script developers know to use.

For example, set the 'Directory' parameter in the 'TBox Take Screenshot' step to "\\ToscaImageServer\images".

If the File Share is set to be hosted by a remote machine (not on the Tosca Server machine), the user identity under which the Tosca Rest Api service runs must be set to a Windows Service Account that has access to the remote UNC path. If the user does not have proper security permissions, the integration will not be able to access images on the File Share and reports will contain blank boxes where images should occur.  Logon to Tosca Commander on the Tosca Server with the service account to establish the license permissions.
