A context isn't necessarily "global state", it's "contextually shared state" hence the name. Of course, you could use it as a global state, but typically you shouldn't do that. Then again, the language locale (like a theme) is actually a compelling case for "application global" state. From a testing perspective, you just wrap the component being tested in a context provider that provides the necessary fixtures for your test case. However, I'd also note that this is probably not an ideal function to test since all that you could possibly be testing is that react context and i8n are working as expected, which is almost certainly outside the scope of your application's testing surface.
