This template generates a table of side-by-side testcases comparing two or more templates. 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.

Parameter Description
_template1
_template2
(etc)
Names of the templates to be processed. _template1's default is the current page's {{basepage}}. If _template1 is specified, the default for _template2 is its /sandbox subpage; if not, the default for _template2 is the /sandbox subpage of the current page's basepage. Template names should be entered as you would use them in a normal template invocation, i.e. "3x", not "Template:3x". If you need to test a page in the main namespace you can use a colon prefix, i.e. ":article name".
_template Alias for _template1. If both _template and _template1 are specified, _template will take precedence.
_showtemplate1, _showtemplate2, _showtemplate3... If this is set to "no", then no output is shown for that template. This is useful if you only want to show the main template, or if you only want to show the sandbox template.
_heading1
_heading2
(etc)
Custom headings for each of the templates.
_showheader If this is set to "no", then no headers are shown.
_class HTML classes for the table. Use |_class=wikitable to format the table as a wikitable.
_style Custom inline CSS for the table.
_caption Custom caption for the table. The default is "Side by side comparison".
_rowheader An extra heading for the row containing the templates.
_heading0 If _rowheader is supplied, this is an optional heading above it in the template row.
_before, _after This text is displayed before or after (respectively) the output of each template. These parameters introduce no whitespace on their own.
_collapsible If set to "yes", the test case is made collapsible. The test case is collapsed and given a green heading if all the template outputs are the same. If any of the template outputs differ, the test case is expanded and given a yellow heading.
_resetRefs If set to "yes", any references generated by the templates tested are reset after each template is expanded.
_showcode Show the template code used to make the test case. If an invocation is specified with the _code parameter, then that is used. Otherwise, an approximation is generated from the arguments. This approximation is not perfect (whitespace in named arguments is lost; duplicate arguments are ignored) but it should be fine for template code that is input all on one line without spaces between parameters.
_code Used to specify template code inside <nowiki>...</nowiki> tags. This is used with the _showcode option to display the template invocation while preserving whitespace. You must use the magic word "__TEMPLATENAME__" instead of the template name. For example: |_code=<nowiki>{{__TEMPLATENAME__|first|second|foo=bar}}</nowiki>. If you find yourself using this option a lot, you may want to consider using {{Test case nowiki}}, which allows you to generate the entire test case from template code in nowiki tags, saving you from typing in all the arguments twice.

Note: due to the way nowiki tags work, the template treats the HTML entities &lt;, &gt; and &quot; as if they were the literal characters <, > and " when used with this parameter.

_format It is possible to use this parameter to display completely different formats, for example test cases arranged in rows. Not all of the parameters here will work with the other formats. For details, see Template:Test case's documentation.
