We build a small run-js-test executable so tests run in a similar environment as gnome-shell, and then wrap it with a generated script that provides environment variables like GI_TYPELIB_PATH. This is more complicated than it needs to be, we can just as well set up the typelib search path from the runner and pass in the environment via meson.
