In the context of a unit test I need to send some code to the console of a chrome app I am developing. It's clear that I can do that from the chrome.debug API, but is there a way to do that from outside the browser?

Yes, there is a way; if you can do something with chrome.debug you can do so with remote debugging.

You need to enable remote debugging with command line switches; you can then connect to Chrome with a debugger client instance.

Google lists some existing debugger clients, and you can implement your own by following the debugger protocol (which works over HTTP+WebSockets).

The procedure for a debugger client is to request /json from the debugger port over HTTP, which lists all possible debug targets; the client then connects to the WebSocket associated with that target to work with it.

could you be a bit more specific? I looked into the protocol a bit but couldn't find a way to set the debuggee to an extension, or even a reference to a debuggee at all. Looking a bit into the code it looks like when the debuggee is another extension the event is dispatched internally and not through the protocol, but I could be wrong about this.
Read the first link; you need to access the /json URL for a list of debuggees and then connect to the appropriate WebSocket port. At least that's how I read it; I haven't tried it myself.
What do I do after connecting via WebSocket?
