Event.Hook Workaround

//New version that's simpler: http://pastebin.com/38jjPhnx

class 'UnitTestManager' (GUIScript)

local this
function UnitTestManager:Initialize()

    self.tests = {}

end

end

function UnitTestManager:RunTests()

    //no trouble using self now when hooked to a console event.

    for i,v in pairs(self.tests) do

//global so it can be called in different test files without having to recreate this line:
UnitTestManager = GetGUIManager():CreateGUIScriptSingle("UnitTestManager")

if not UnitTestManager_Hooked then //wrapped in if so that saving changes to this file won't cause additional hooks
    UnitTestManager_Hooked = true

    local function Test()
        UnitTestManager.RunTests(this) //this = self of the instance.
