I'm not 'self', but anyhow...

Once we have a js build, do you envision two test configurations (one for the build (release), one for the raw (debug)?). We had 2 different once in mf-next because raw (or debug) mode would support TDD and doesn't need a build round-trip. But mf-next also used closure compiler in advanced mode... For the record: I could live with a release test build only (as the js build will likely be fast enough).
