I would presume that the "Test" button of ungrounded GFCI receptacles will not work, is that correct?
How essential is monthly GFCI testing?
Does replacing a 2 prong receptacle with a GFCI receptacle and then replacing the downstream 2 prong receptacles with 3 prong receptacles meet code requirements?
You would presume incorrectly.
Yes, if you put a "GFCI protected. No equipment ground" sticker on each of the downstream receptacles. Do not connect the grounds together unless you actually run a grounded wire to one of them.

The GFCI testers have a path from hot to ground, like you would think; but the GFCIs themselves go from hot to neutral.
