[Test-Equipment] testing semiconductors

[Rasputin Novgorod]

While reading thru back messages (perhaps in a discussion 
about power supplies), someone said that the usual fault is
blown semiconductors. They suggested to quickly meter across
all the leads of each semiconductor for shorts or open
(i.e. obviously blown).

I'd be grateful if someone elaborate further, is simple language
about quick semiconductor testing.
(i.e. think "Dummys guide to electronic Repairing...".
What is obvious to you pro's, is intimidating to we beginners.

1) Can the tests be done in-circuit? 
2) Can a digital or analogue VOM be used?
3) What are the meter settings?
4) All semiconductors? (FETs, Triacs, etc).
5) Can small parts be damaged by testing?

Sincerely
