“ Each template is called with the same parameters.
All parameters passed to this template are passed through to the test-case templates, with the exception of parameters starting with an underscore character ("_") , which are reserved for internal use.
If no templates are specified explicitly, the module uses the base page of the current page as the first template, and its /sandbox subpage as the second template. If only one template is specified explicitly, its /sandbox subpage is used as the second template. ”
