what is difference between smoke & sanity testing?

Answer Posted / dhinesh

SMOKE TESTING:

Smoke testing originated in the hardware testing
practice of turning on a new piece of hardware for the first
time and considering it a success if it does not catch fire
and smoke. In software industry, smoke testing is a shallow
and wide approach whereby all areas of the application
without getting into too deep, is tested.
A smoke test is scripted, either using a written set of
tests or an automated test
A Smoke test is designed to touch every part of the
application in a cursory way. It’s shallow and wide.
Smoke testing is conducted to ensure whether the most
crucial functions of a program are working, but not
bothering with finer details. (Such as build verification).
Smoke testing is normal health check up to a build of an
application before taking it to testing in depth.

SANITY TESTING:

A sanity test is a narrow regression test that focuses
on one or a few areas of functionality. Sanity testing is
usually narrow and deep.
A sanity test is usually unscripted.
A Sanity test is used to determine a small section of
the application is still working after a minor change.
Sanity testing is a cursory testing, it is performed
whenever a cursory testing is sufficient to prove the
application is functioning according to specifications. This
level of testing is a subset of regression testing.
Sanity testing is to verify whether requirements are met
or not, checking all features breadth-first...
