May I suggest a different setup?

What about


and then use only

require "Tests.Component1.Feature1"

whenever you need to test feature1 from component1. The file could be only

module "Tests.Component1"
... some more code to implement tests for feature 1.

Notice that you can have more than one FeatureN file using the same module
namespace (although local functions won't be visible among the different

That is the part that I'm still puzzled about. If you require
"Tests.Component1.Feature1" before anything, there shouldn't be any global
"Component1", but even if there is one such global, there will be no name
clash, since the module is supposed to be referenced by the global "Tests",
not "Component1".

I have to agree that sometimes it is impossible to prevent name clashing,
but usually a tool like what yours seems to be can be loaded before the user
scripts that will use it. So the name clashing is more easily avoidable (as
long as your users agree to skip the use of "Tests" or you accept to name
your module something else that they agree to not use).

I have to insist that apparently that is not the issue here, using the above
namespace scheme should make things easier for you and your users, no?
