Using Optional TestElement Properties
When you implement the TestElement class, you can also use two optional attributes, PersistenceElementName and UserVisibleProperty.
The UserVisibleProperty determines whether the test property appears for the test in the Properties window.
Use the DefaultValue attribute to set a default value to use if the field in the test property has no value.
Use TestCaseManagementDisplayName to set a localizable name to use in the Properties window.
