When your Lua code does crash, it&rsquo;s usually inside someone else&rsquo;s host process, which makes testing <em>more</em> important, not less. The good news: the ecosystem has consolidated around two real frameworks and one essential assertion layer — <strong>Busted</strong> (1,635 stars, the BDD standard), <strong>LuaUnit</strong> (633 stars, the single-file xUnit workhorse, now on version 3.5 with Lua 5.5 support), and <strong>luassert</strong> (250 stars, the extensible assertion and spy engine that powers Busted and works standalone).</p>
