Support for Enums in Test Scenarios

The Test Scenario (not legacy) doesn't have support for Enum types. The test scenario table doesn't include the option to select a particular value from the Enum.

The Enum is appearing for selection in the tree view, but the only attribute available for selection is the "declaringClass". See attached image.

Proposal: add the Enum values to the tree view so users can add the Enum value to the table (GIVEN or EXPECTED).
