Checking for the Execution Mode and User Privileges Using the TestStand API

You may want to restrict functionality of your code module using various criteria. These criteria may include, TestStand user privileges and whether your current execution is in normal or interactive mode.

If you want to verify in an expression that the current user has a specific privilege, call the CurrentUserHasPrivilege expression function. If you want to verify the privilege in a code module, as in this example, call the CurrentUserHasPrivilege method of the Engine class in the TestStand API.

Checking privileges can also be used to restrict functionality of TestStand tools and operator interface features. By default, TestStand automatically limits the sequence editor and operator interfaces functionality depending on the privilege settings that the user manager stores for the user who is currently logged in. These restrictions can be disabled through the User Manager tab of the Station Options dialog box. For more information on user privileges refer to Chapter 12, " User Management", of the "TestStand UserManual".

You can execute a sequence as a normal execution or you can run sequence steps in interactive mode. You may want to have restricted functionality based on the mode of execution. If you want to check whether the execution that called your code module is in interactive mode, call the InteractiveMode method of the Execution class in the TestStand API. For more information on normal and interactive executions, refer to the "Sequence Execution" section of Chapter 1, "TestStand Architecture Overview", in the "TestStand User Manual".
