This could work. How would I provide my users with the ability to load all
the tests for component1? How would they load the tests for all the
components? (BTW: I think there was a discussion on this somewhere else)

I've managed to reduce all of this into 1 file that demonstrates the issue.
Put all of this into ./Tests.lua. One could also distribute it over the files
as indicated by the comments
module "Tests"
--require 'Tests.Component1'
-- In ./Tests/Component1.lua
--require "Tests.Component1.Feature1"
-- In ./Tests/Component1/Feature1.lua
module "Tests.Component1"
Start Lua and assign something to the global variable Component1. Now require
'Tests' e.g.
- Component1 = function() end
- require 'Tests'
The response I see is (Lua 5.0.2, compat-5.1r2):
compat-5.1.lua:122: name conflict for module `Tests.Component1'
stack traceback:
[C]: in function `error'
compat-5.1.lua:122: in function `module'
Tests.lua:8: in function `f'
compat-5.1.lua:79: in function `require'
stdin:1: in main chunk
[C]: ?
By making the change to getfield(), this will work.
