My interpertation of the AngularJS DI implementation is that it exists primarily to make it easy to swap items out for testing purposes. I believe it solves that problem very well.

What alternatives do you recommend to DI?




Nothing, for swapping things out. :)

In my test initialization, I'd probably just replace the value of "ns.someService" worldwide with a mock.

Having a window-wide namespace might make sense in the test, but it is pretty risky/limiting if you are writing a component that should be reused in contexts you don't fully control. There are other ways around that besides DI, but they will probably have similar trade-offs in safety EOU, etc.
