This template creates a test case of two or more templates contained in a box. If the outputs of all the templates is the same, the box is collapsed, but if any of them differ from each other the box is left uncollapsed. There are a variety of different formats and options that can be used.
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.
