   I'm probably doing this wrong, and it's not even supposed to work; but run-in-roblox fails on linux (due to the roblox-install crate not yet supporting vinegar or vinegar flatpak) so I thought I'd try running jest in lune.

   (Copilot) hacked at this for a minute, so it has the pcall and the comment about Packages.Project (which is necessary due to Rojo/wally iiuc?)

   local ReplicatedStorage = nil
   local runCLI = nil
   
   local isLune = (_VERSION:gmatch("Lune")() == "Lune")
   if isLune then 
   	-- local roblox = nil
   	-- local ok, mod = pcall(require, "@lune/roblox")
   	-- if ok then
   	-- 	roblox = mod
   	-- else
   	-- 	print("ERROR: require('@lune/roblox') failed")
   	-- end
   	local roblox = require("@lune/roblox")
   	local Instance = roblox.Instance
   
   	local game = Instance.new("DataModel")
   	local _workspace = game:GetService("Workspace")
   
   	print("DEBUG: @lune/roblox: game=Instance.new('DataModel') => " .. tostring(game) .. " type=" .. typeof(game))
   	assert(game ~= nil)
   
   
   
   	-- Create ReplicatedStorage, DevPackages, and Packages folders
   	-- ReplicatedStorage = Instance.new("Folder")
   	-- ReplicatedStorage.Name = "ReplicatedStorage"
   
   	ReplicatedStorage = Instance.new("ReplicatedStorage")
   	--game.ReplicatedStorage = ReplicatedStorage
   
   	local DevPackages = Instance.new("Folder")
   	DevPackages.Name = "DevPackages"
   	DevPackages.Parent = ReplicatedStorage
   
   	local Packages = Instance.new("Folder")
   	Packages.Name = "Packages"
   	Packages.Parent = ReplicatedStorage
   
   	-- Insert Jest as a ModuleScript-like table
   	--local jestModule = require("./stemgame/DevPackages/_Index/jsdotlua_jest@3.10.0/jest/src/init.lua")
   	local jestModule = require("./DevPackages/Jest")
   	DevPackages.Jest = jestModule -- TODO: this is going to fail
   
   	-- Is there a way to rojo_require("./default.project.json") here
   	-- Or is it better or only possible to create the .rblxm with rojo and then deserializePlace(place.rblx)
   
   
   
   	-- You may need to insert your Project module into Packages.Project here if your tests require it
   	-- Example: Packages.Project = require("path/to/your/project/init.lua")
   
   	runCLI = DevPackages.Jest.runCLI
   else
   	ReplicatedStorage = game:GetService("ReplicatedStorage")
   	runCLI = require(ReplicatedStorage.DevPackages.Jest).runCLI
   end
   
   local processServiceExists, ProcessService = pcall(function()
   	return game:GetService("ProcessService")
   end)
   
   local status, result = runCLI(ReplicatedStorage.Packages.Project, {
   	verbose = true,
   	ci = false
   }, { ReplicatedStorage.Packages.Project }):awaitStatus()
   
   if status == "Rejected" then
   	print(result)
   end
   
   if status == "Resolved" and result.results.numFailedTestSuites == 0 and result.results.numFailedTests == 0 then
   	if processServiceExists then
   		ProcessService:ExitAsync(0)
   	end
   end
   
   if processServiceExists then
   	ProcessService:ExitAsync(1)
   end
   
   return nil

   (Perhaps pesde would be easier for this. Though FWIU pesde supports installing wally packages (and git repos) but not rojo sync?)
