BrodyFosse's version might be correct for certain preliminary readings that don't have an invited audience, but Devil Wears Prada was a much different situation.
For the Devil Wears Prada "reading," they rehearsed for 2 weeks in the mornings/afternoons, working around people with matinee schedules. The presentations were performed at music stands, with the cast reading the book and singing the songs, for an invited audience of investors, theatre owners, etc. I believe the Equity agreement was a "Tier 1" development contract.
Often, a musical will just do a "29 Hour Reading." They'll have about 25 hours of rehearsal (learn the music, read through the script a few times, do a bit of character work, etc). The presentation is typically the full book and score (or whatever is written of it) at music stands, with piano or a small band. The presentation happens in a rehearsal studio or in an off-Bway theatre. It's a way for producers to raise money, but also to see a show performed by actors so they can say "this scene/song works, that doesn't; we like this actor, that actor shouldn't continue with the project."
