Scribunto offers a simple REPL in the module edit page to quickly test changes made to module code, but it doesn't take actual template variables as inputs, and it's hard to replicate conditions like transclusion. With Wikitext and ParserFunctions, we have Special:ExpandTemplates to do this quicker than repeatedly editing and saving a page, but no such equivalent with Lua.
Is there a method or neat "trick" to feed page and template parameter contents to a Scribunto module without repeatedly editing/saving a page? As someone that's still learning Lua, any help is appreciated
