smoke and mirrors
= S =
smoke test n.
1. A rudimentary form of testing applied to
electronic equipment following repair or reconfiguration, in which
power is applied and the tester checks for sparks, smoke, or other
dramatic signs of fundamental failure. See magic smoke.
2. By extension, the first run of a piece of software after
construction or a critical change. See and compare reality check.
There is an interesting semi-parallel to this term among
typographers and printers: When new typefaces are being punch-cut
by hand, a `smoke test' (hold the letter in candle smoke, then
press it onto paper) is used to check out new dies.
