== Multiple automatic sandbox versions ==
Can we please extend the automatic addition of a <code>/sandbox</code> variant to all <code>_template<var>i</var></code>s if there is no <code>_template<var>++i</var></code>?
— [[User:Crissov|Christoph]] [[User talk:Crissov|Päper]] 11:14, 20 September 2019 (UTC)

== Table with many tests ==
For some templates, especially inline templates like {{tl|frac}}, it makes sense to have all or most test cases in a single table with one combination of parameters per row. It would be nice if this could be handled by a single function call by passing multiple parameter sets, e.g.:
<syntaxhighlight lang=mediawiki>
{{test case|_template1=frac|_template3=sfrac
|_test1={1}      |_label1=single anonymous parameter, numeric
|_test2={1,2}    |_label2=two anonymous parameters, all numeric
|_test3={1,2,3}  |_label3=three anonymous parameters, all numeric
|_test4={1=1}    |_label4=single, first parameter
|_test5={2=1}    |_label5=single, second parameter
|_test6={3=1}    |_label6=single, third parameter
|_test7={1,3=2}  |_label7=first and third parameter
|_test8={2=1,3=2}|_label8=second and third parameter
|_test9={a}      |_label9=single anonymous parameter, alphabetic
|_test10={1,1}   |_label10=two equal parameters
}}
</syntaxhighlight>

: Alternatively, there should be an additional rendering mode ''cells''. It would put the code and each result for all templates and sandbox versions into adjacent cells in a single table row, but the user would have to provide the surrounding table code (but possibly not the rows <code>|-</code>). — [[User:Crissov|Christoph]] [[User talk:Crissov|Päper]] 10:16, 1 January 2020 (UTC)

== Hyphen issue in [[Template:Test case nowiki]] ==

This came up when I was working on [[Template:Graphical timeline/testcases]]. At [[Special:Permalink/958740301]] it can be observed that parameter {{para|note3-at}} gets a broken value. First character, hyphen, is correct, however, the first opening brace {{(}} of {{tnull|Period start}} is converted into an [[HTML entity]] for some reason. This results in an error {{tq|<nowiki>Expression error: Unrecognized punctuation character "&"</nowiki>}} somewhere deep inside the template's internals. I've added [[Template:Test_case_nowiki/testcases#Hyphen_prefix_inside_nowiki_tag|a test case to demonstrate the issue on a smaller example]]. —⁠[[User:Andrybak|andrybak]] ([[User talk:Andrybak|talk]]) 13:38, 25 May 2020 (UTC)

== How to specify page name? ==

I looked through the documentation, but I was unable to find a way to specify the page name (magic word PAGENAME) in a template test case. For templates that use Wikidata calls, for example, the Wikidata call checks the PAGENAME and retrieves the appropriate bit of data from the corresponding Wikidata page. Is there a way to do this? The result would be to render the template as it would appear when processed by [[Special:ExpandTemplates]] with the appropriate PAGENAME entered in the upper text field. – [[User:Jonesey95|Jonesey95]] ([[User talk:Jonesey95|talk]]) 22:55, 23 July 2020 (UTC)
:Partial answer, still looking for a real answer: A possible workaround is to use {{para|qid}} in your infobox. See [[Template:Ordination/testcases]] for an example. – [[User:Jonesey95|Jonesey95]] ([[User talk:Jonesey95|talk]]) 01:23, 3 August 2020 (UTC)

== Paragraph break when using {{tl|inline test case}} ==

This is probably something silly I am doing, but I can't figure out what. I am using {{tl|inline test case}} in the testcase page of [[Template:Cite certification]] and from some reason I am sometimes (rarely) getting an extra paragraph break between results. I created an example: [[Template:Cite certification/testcases-example]]. I was worried that there is something wrong with the {{tl|Cite certification}}, but as you can see from the code in the example, the paragraph break does not appear when running either the stable or the (identical) sandbox versions. Any ideas? --[[User:Muhandes|Muhandes]] ([[User talk:Muhandes|talk]]) 14:46, 31 December 2020 (UTC)

== Sandbox2, Test case2, and wrapperConfig ==

I'd like the ability to use a second sandbox, say, 'sandbox2', to enable simultaneous testing of different sets of changes in parallel tracks for the same template. Having browsed [[Module:Template test case]], I believe a better method is available than the obvious brute force method of duplicating template FOO to FOO2, then FOO2/sandbox, and testcases to FOO2/testcases. Afaict the key seems to have something to do with {{var|wrapperConfig}} unless I'm mistaken, only I don't see how to use it, and the /doc doesn't have much to say about it.

This use case comes up occasionally in RL on complex templates that may need extended testing of some feature, while someone else desires to test another feature, or where different scenarios are being tried out. (For a RW case of the former type see [[Template talk:Find sources#Missing redirect detection bug]].) I get the feeling I can just create [[Template:Find sources/sandbox2]] with my changes, and then create a "wrapper config" somewhere, and set it as param2 to the invoke. 

For example, can I just duplicate [[Module:Template test case/config]] to Template:Find general sources/MySandbox2Config, edit it to set <code>sandboxSubpage = 'sandbox2',</code> and then in Template:Find general sources/sandbox2 invoke like this: {{tlc|#invoke:Find sources|Find general sources, MySandbox2Config}}? Or am I misconstruing how this is supposed to work, and I should go back to the brute force method? Or something else? Pinging {{ping|Mr. Stradivarius|Trialpears}}. 

Either way, param2 of the module appears to be a config of some kind, so whether my assumptions above are right or wrong, it would be nice if someone could add a <code><nowiki>== Params ==</nowiki></code> section to [[Module:Template test case/doc]] to describe what this param is and how to use it. {{pme}} [[User:Mathglot|Mathglot]] ([[User talk:Mathglot|talk]]) 22:28, 25 December 2021 (UTC)

:{{reply|Mathglot}} You can use a second sandbox by setting the {{para|_template1}}, {{para|_template2}} and {{para|_template3}} arguments. For example, <code><nowiki>{{test case|_template1=Find sources|_template2=Find sources/sandbox|_template3=Find sources/sandbox2|Foo}}</nowiki></code> outputs the following:
{{<nowiki>test case</nowiki>|_template1=Find sources|_template2=Find sources/sandbox|_template3=Find sources/sandbox2|Foo}}
:The module is built so that the default value for _template1 is the base page of the current page, and the default value for _template2 is its sandbox subpage. In fact, if you are calling the module from [[Template:Find sources/testcases]], you could omit the {{para|_template1}} and {{para|_template2}} arguments, and just specify {{para|_template3|Find sources/sandbox2}} to get the same results. — '''''[[User:Mr. Stradivarius|<span style="color: #194D00; font-family: Palatino, Times, serif">Mr.&nbsp;Stradivarius</span>]]''''' <sup>[[User talk:Mr. Stradivarius|♪&nbsp;talk&nbsp;♪]]</sup> 01:17, 26 December 2021 (UTC)
::As for the config file, this is not intended to be specified by users. I believe I allowed the config to be passed to the main function so that it can be more easily tested, but this ability is not currently used by [[Module:Template test case/testcases]]. I probably only used it in the console during initial development. Also, the config cannot be passed from wikitext; it needs to be passed from another Lua module. From wikitext you can only influence the contents of the first parameter (the frame object) to the function called from #invoke; you can't influence the contents of subsequent parameters. — '''''[[User:Mr. Stradivarius|<span style="color: #194D00; font-family: Palatino, Times, serif">Mr.&nbsp;Stradivarius</span>]]''''' <sup>[[User talk:Mr. Stradivarius|♪&nbsp;talk&nbsp;♪]]</sup> 01:45, 26 December 2021 (UTC)

== format=columns + inline hybrid ==
I've a bunch of test cases for a template that takes lots of complicated parameters, but whose output is a relatively short text. Think {{tl|cite book}} and you're in the ballpark. I want to see the code up top in a nowiki block like {{tlx|test case nowiki|format{{=}}columns}} or {{para|format|rows}} gives me, but I'd like to see the output arranged vertically like {{tlx|test case nowiki|format{{=}}inline}} gives me.

Something like:
{{cot|Example of desired output}}
<code><pre><nowiki>{{example
 |first-argument = has a value
 |second-argument = does too
 |veni-vidi-vici = yes
 |lipsum = lorem
}}</nowiki></pre></code>

== Use of _before and _after ==

I'm trying to use the {{para|_before}} parameter, mostly to have something to hange templates that create superscript references, tags, and that sort of thing, so they don't appear to be isolated in space.  What I'd like to see in this example, is something like this:
: Some text to hang a tag on.{{Citation needed|reason=Some reason.|date=January 2023}}
Here's my test case, using {{para|_before}}:

<div style="border:2px solid PaleVioletRed; margin:0 0 0.5em 1.6em;padding:0.2em 1em;background-color:#D8FED8">

{{Test case|_before=Some text to hang a tag on.|_code=on|_template1=Citation needed|_template2=Citation needed/sandbox|reason=Some reason.|date=January 2023}}
</div>

Am I doing something wrong, here? Why isn't it echoing the "before" text? [[User:Mathglot|Mathglot]] ([[User talk:Mathglot|talk]]) 04:29, 26 January 2023 (UTC)
:{{ping|Mathglot}} You aren't doing anything wrong. It seems the _before (and _after) option wasn't implemented for all render (_format) methods (There's 5, which are columns, rows, inline, cells, and default - only columns and cells considered _before, and your example renders in default since nothing was specified).

== Using syntaxhighlight when _showcode is used ==

I've changed the {{tag|code}} tags to {{tag|syntaxhighlight}} tags when {{para|_showcode}} is used. [[Module:Template test case/sandbox|Sandbox]] and [https://en.wikipedia.org/w/index.php?title=Special%3AComparePages&page1=Module%3ATemplate+test+case&page2=Module%3ATemplate+test+case%2Fsandbox Diff]. [[User:Gonnym|Gonnym]] ([[User talk:Gonnym|talk]]) 18:04, 23 May 2023 (UTC)

:Hmm. Would it make sense to have that be opt-in, at least initially, by adding a new {{para|format|syntaxhighlight}} (and/or {{para|format|syntax}} maybe) instead? Are there any weird border cases where {{tag|code|content={{tag|nowiki}}}} works, but {{tag|syntaxhighlight|attribs=lang{{=}}"mediawiki" inline}} might break? [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 04:00, 15 July 2023 (UTC)

== Inconsistency between Test case nowiki and others ==

So, in most of the test case templates, you pass arguments to the test-case code preceded by underscores, and actual arguments to the template being tested are passed as usual, e.g.:
<syntaxhighlight lang="mediawiki">
{{Test case|_collapsible=yes|_showcode=yes|_title=Some test case
|_template1=Code
|1=wikitable
}}
</syntaxhighlight>

OK, great. But then here comes {{tlx|Test case nowiki}}, where the underscore arguments don't work, and you have to use non-underscored ones:

===BAD===
<syntaxhighlight lang="mediawiki">
{{Test case nowiki|_collapsible=yes|_showcode=yes|_title=Some test case
|_template1=Code
|<nowiki>{{__TEMPLATENAME__
|1=wikitable}}</nowiki>
}}
</syntaxhighlight>

===Works===
<syntaxhighlight lang="mediawiki">
{{Test case nowiki|collapsible=yes|showcode=yes|title=Some test case
|template1=Code
|<nowiki>{{__TEMPLATENAME__
|1=wikitable}}</nowiki>
}}
</syntaxhighlight>

My question is, '''''why'''''??? If these templates are a "family", and so often used together, doesn't it make sense for {{tlx|Test case nowiki}} to take the same set of arguments that {{tlx|Test case}} and all the others take? Even if it's not strictly ''necessary'' for them to be preceded by underscores? It would make converting test cases between the non-nowiki and nowiki versions a lot quicker and more convenient. Am I really the only person who finds themselves doing that pretty frequently? [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 06:33, 15 July 2023 (UTC)

:The technical reason for why comes down to [[Module:Template test case#L-770|this bit of code]], in which the nowiki wrapper has its arguments done differently. The reason I think this was done in practice is because the only reason the underscores are used in the {{tl|Test case}} version is because you have to provide the real arguments, so prefixing the options with _ prevents conflicts. Since the nowiki version just takes the parameter 1, it had no need for the underscores. [[User:Aidan9382|Aidan9382]] <sub>([[User talk:Aidan9382|talk]])</sub> 06:57, 15 July 2023 (UTC)

== Trim input's newlines? ==

Many people use {{tl|test case nowiki}} as follows for aesthetics:

This causes an extra newline to be inserted before and after the template's part inside the test case frame. It would be wonderful if this module would trim the input's newlines.

== Having multiple __TEMPLATENAME__s ==

I wanted to gauge interest in possibly extending the Module code to (optionally) support testing nowiki'd code that contains ''multiple'' template name substitutions. The primary use case would be testing templates that are only useful in concert with others, like (for example) {{tlx|archive top}}.

It's certainly possible to test that template in isolation, using a {{tlx|Test case nowiki}} transclusion at [[Template:Archive top/testcases]] like:

<syntaxhighlight lang="mediawiki">
{{Test case nowiki|<nowiki>
{{__TEMPLATENAME__}}
{{Lorem ipsum}}
{{archive bottom}}
</nowiki>}}
</syntaxhighlight>

...That'll get you a perfectly good test of {{tlx|archive top}} vs. {{tlx|archive top/sandbox}}.

But it might be useful, at times, to pair the tested {{tlx|archive top}} with a '''corresponding''' {{tlx|archive bottom}}, for when changes being made in tandem are being tested.

To meet those needs, the Module might need to support something like the following:

<syntaxhighlight lang="mediawiki">
{{Test case nowiki|template1name1=archive top|template1name2=archive bottom|<nowiki>
{{__TEMPLATENAME1__}}
{{Lorem ipsum}}
{{__TEMPLATENAME2__}}
</nowiki>}}
</syntaxhighlight>

This would, my thinking goes, permit testing the '''''combination''''' of {{tlx|archive top}} and {{tlx|archive bottom}} against the '''''combination''''' of {{tlx|archive top/sandbox}} and {{tlx|archive bottom/sandbox}} (unless different templates were specified for {{para|template2name1}} and {{para|template2name2}}).

As with the citation templates' handling of {{para|author}}, {{para|first}}, {{para|last}}, etc.:

# {{para|template1}} would effectively become an alias for {{para|template1name1}} (with the same default of <syntaxhighlight lang="mediawiki" inline>{{#titleparts: {{PAGENAME}}| -1}}</syntaxhighlight>)
# Same for {{para|template2}} and {{para|template2name1}} (again having the same default of <syntaxhighlight lang="mediawiki" inline>{{{template1name1}}}/sandbox</syntaxhighlight>)
# {{para|template3}} == {{para|template3name1}}, etc.
# <code>__TEMPLATENAME__</code> would be interchangeable with <code>__TEMPLATENAME1__</code>. 

Using only {{para|template1name1}}, {{para|template2name1}}, and <code>__TEMPLATENAME1__</code> would therefore be equivalent to the current syntax, as would using ''only'' <code>__TEMPLATENAME1__</code> and leaving the template-selection parameters at their default values.

...Potentially useful? Some flaw I've overlooked in the proposed functionality? Or just not worth the effort, regardless whether or not it would work? [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 18:21, 29 August 2024 (UTC)

:I've since decided that the parameter names {{para|template1name1}} and {{para|template1name2}} feel awkward and confusing. They '''should''' be {{para|template1name1}} and {{para|template2name1}}, if anything, but that won't work because {{para|template1}} and {{para|template2}} are existing parameters that have different, incompatible definitions in the code.
:Nevertheless, a call using e.g. {{para|template1name1|archive top}}{{para|template1name2|archive bottom}} just feels confusing. (They're '''not''' different ''names'' for the first template, they're ''different '''templates''''' to be used in the first rendering of the test case.)
:So to avoid that confusion, I think it would be better to make {{para|templatename1}} the new equivalent for {{para|template1}}, instead. The second template to use in rendering the test case would be just {{para|templatename2}}. {{para|template2name1}} would still be equivalent to {{para|template2}}, and {{para|template2name2}} would still be the corresponding equivalent to {{para|templatename2}} for the second rendering of the case. (Though often they'd not be specified, and default to the {{code|/sandbox}} versions of the templates specified for {{para|templatename1}} .. {{para|templatename<var>N</var>}}. The notion of a "{{param|template1}}" parameter would be a deprecated compatibility labeling — the "proper"/"preferred" identifiers would be {{param|templatename1}} ... {{param|templatename<var>N</var>}}. Which, handily, would also exactly correspond to the placeholder strings {{code|__TEMPLATENAME1__}} ... <code>__TEMPLATENAME<var>N</var>__</code> used to insert them into the nowiki'd code.
:The other option would be {{para|case1template1}} ... {{para|case1template<var>N</var>}} for the first rendering, then {{para|case2template1}} ... {{para|case2template<var>N</var>}} for the normally-defaulted-to-<code>/sandbox</code> versions, and so on... But that's a much bigger and more disruptive change that doesn't feel worth the upheaval. (It also changes the meaning of "template1" vs. "template2", compared to their current definition. So, still potentially confusing.) [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 03:47, 7 October 2024 (UTC)

== Why visual matches instead of string matches? ==

Sorry for what must be a silly question, but why does this tool require visual comparison rather than doing a match and emitting '''TEST FAIL!''' [[User:Johnjbarton|Johnjbarton]] ([[User talk:Johnjbarton|talk]]) 22:19, 6 October 2024 (UTC)

:Not sure I follow — a string comparison of the output is precisely what the module's <syntaxhighlight lang="lua" inline>TestCase:templateOutputIsEqual()</syntaxhighlight> function does; the {{tlx|Collapsible test case}} template — or any of the templates, with {{para|_collapsible|yes}} set — will even automatically collapse any testcase where the results are the same. (As well as coloring the top bar of the collapsible box green (same output) vs. yellow (differences detected).)
:However, it's often the case that differences between the main version of a template and its sandbox version are '''intentional'''. (They'll be present whenever development is being done on the sandbox version of the code, for example.) So, characterizing differences as "TEST FAIL!" isn't strictly accurate, as having the same output isn't "success" and having ''different'' output isn't "failure". The point, when there are differences, is to demonstrate/examine how/whether the sandbox version has '''improved''' the output, vs. the live code. (If so, then a request can be made to transfer the sandbox code to the live template. At which point, the differences go away.) [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 23:38, 6 October 2024 (UTC)
:(Template test cases are therefore not like traditional programming [[unit test]]s, where the result of some code is compared to a known expected value, and any deviation represents a failure to perform as expected. Template test cases compare and contrast two versions of the same template, and any differences in output are ''interesting'' as a means of evaluating the code changes that created those differences.)

:::::@[[User:Zygimantus|Zygimantus]] For starters I think you need to configure https://lt.wikipedia.org/wiki/Module:Template_test_case/config for the wiki — in particular, the <code>wrappers</code> table, which the module uses to map names of templates to the functions and arguments they should use.
:::::If you notice, all of the templates related to [[Module:Template test case]] all contain the same code:
:::::<syntaxhighlight lang="mediawiki">{{#invoke:Template test case|main}}</syntaxhighlight>
:::::That's because, when the module sees it's being invoked from e.g. [[Template:Testcase table]], the <code>wrappers</code> table tells it to automatically add <code>_format = 'columns'</code> to the arguments. But on your wiki the module will never be invoked from [[Template:Testcase table]], it'll be invoked from [[lt:Šablonas:Testcase table|Šablonas:Testcase table]], and there's no wrapper mapping for that <s>template</s> page name. That's, at the very least, why your test cases are being formatted as rows instead of columns.
:::::It may not be the ''whole'' issue, but it's definitely '''an''' issue.
:::::You're also missing [[Module:Suppress categories]], which the your [[lt:Šablonas:Suppress categories|Šablonas:Suppress categories]] depends on. (Discovered by editing the testcases page, then selecting "Templates used" in the hamburger menu and looking for redlinks in the resulting list — a handy way to root out broken dependencies. There are a few others.) [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 06:09, 25 October 2024 (UTC)
::::::{{Reply|FeRDNYC}} thanks. I had to translate „Template“ text in that config page. Also I wasn't aware that on local wikis these pages are not the same: [[:lt:Šablonas:Testcase table]] and [[:lt:Template:Testcase table]]. For example, if you click on those links, they will direct to same page, but on Module page it works not like that I suppose.

:::::::@[[User:Zygimantus|Zygimantus]] Yeah, the problem is that [[lt:Template:Testcase table]] acts as an '''alias''' for the canonical name — which works fine, going ''in'', because you end up at the same place. But it doesn't work in reverse, so when the module asks "What template am I being called from?", the answer will never be "Template:Testcase table"; that's not what the page is called.

== Option to invoke a module ==

It would be helpful if this module could be test module output. For example instead of {{para|_template=xyz}} we had something like {{para|_module|xyz}} and {{para|_function|def}} which would pass the arguments to <code><nowiki>{{#invoke:xyz|def|...</nowiki></code> and <code><nowiki>{{#invoke:xyz/sandbox|def|...</nowiki></code> and compare the results &mdash;&nbsp;Martin <small>([[User:MSGJ|MSGJ]]&nbsp;·&nbsp;[[User talk:MSGJ|talk]])</small> 21:54, 23 January 2025 (UTC)

::From a quick read of the documentation, it seems to be possible to force a module test if you use {{tl|Test case nowiki}}, e.g. <syntaxhighlight lang=wikitext inline>{{Test case nowiki|template=Disambiguation|heading1=[[Module:Disambiguation]]|heading2=[[Module:Disambiguation/sandbox]]|<nowiki>{{#invoke:__TEMPLATENAME__|isDisambiguationPage|Paris}}</nowiki>}}</syntaxhighlight>.

== Similar module with known answer rather than live v. sandbox==

This module compares the live result to the production result. I'm interested in comparing the live result, production result, or both to a known good result. For example, I'm testing date-related templates. I have a book with a list of information about dates, such as the Gregorian calendar date, Julian calendar date, [[Julian day]], and day of the week. I'd like to compare the result from a template to what this book says the result should be.

Any suggestions? [[User:Jc3s5h|Jc3s5h]] ([[User talk:Jc3s5h|talk]]) 11:53, 18 March 2025 (UTC)
