Heard this word from PM, wonder what's it.
Got it from wiki page.
http://en.wikipedia.org/wiki/Smoke_testing
now some general understanding now.
Smoke testing refers to physical tests made to closed systems
of pipes to detect cracks or breaks. By metaphorical extension, the term
is also used for the first test made after assembly or repairs to a
system, to provide some assurance that the system under test will not
catastrophically fail. After a smoke test proves that "the pipes
will not leak, the keys seal properly, the circuit will not burn, or the
software will not crash outright,"[citation needed] the system is ready for more robust testing.
The term smoke testing is used in several fields, including electronics, software development, plumbing, woodwind repair, infectious disease control, and the entertainment industry.
