[Rathoz]

Summary

Setup automated testing using the busted framework

[Rathoz]

will all tests need to be adjusted like logic, array and abbr?

Yup

okay so far, assume you want to convert all the test modules before final review

Will start with a subset, not all. Some are quite annoying as we don't have a MW environment running exactly, so need to fake or mock it

Do we not care about VariablesLua.varexists( name ) and VariablesLua.var_final( name, default ) btw?

Added varexists. But not doing var_final. var_final is deprecated since MW 1.35, and basically never worked in lua

Think I'm done with migrating tests for this PR, so feel free to review

Why the need to implement mw.text.split() functionality but no others?

Was used in a few tests indirectly, Date/Ext and Flags. It's not the complete MW implementation, but probably something good enough for now.

I was looking at bringing over Scribunto as a gitmodule (not lua file), but most of their implementations are dependent on PHP, with the only PHP free libraries being ustring and html, the rest have some dependency on PHP.
