Honestly, your best bet is to measure that stuff before you put it on the board. The last company I started used MyData pick and place machines which would electrically test each component before it was placed. That way, you know the part is good when you put it down. Once in circuit, you can do a signature analysis on a part to see if it "looks rigt", but there really isn't a good way to check its absolute value unless you can isolate it.
