Personally, I found it most convenient to launch my app using ssh on my phone for language testing (my app doesn't run in the emulator anyway).
To test another language, simply change the LC_ALL variable before launching the app, like this for example:
$ LC_ALL=zh_CN.utf8 jolla-settings
Obviously you'll need to replace jolla-settings with your app's binary name.
You can get a list of all supported languages by running:
$ locale -a
This approach should also work with the emulator using either SSH or a terminal...
