Hai

According to me
smoke testing and sanity testing  both are same,but some 
organizations follow the smoke r sanity testing after 
receiving the build from the dev the testers check whether 
the high level functionalities of the app working correctly 
r not.

Dear Sujatha
 smoke testing and sanity testings are not same in real.
ofcourse some companies may treat both are same but you 
cannot give this answer in intervew.

to avoid Unnecessary confusion,you must know the root from 
where these words are originated.

here the word Smoke testing is barrowed from electronics 
testing industry.
In electronic manufacturing process after designing the 
circuit they will put  it for testing.
if there is any fault or miswiring or Miscontacts are there
in circuit then smoke comes out from the circuit.

This testing is called a Smoke testing.
In software industry after build is released from 
development team it will be installed in the test server or
testers PC.
Initial test will be conducted to to check the Build 
stability by checking the software properly working without
any hangings .
The software navigation controls must work smoothly.
so this can be called Build verification Testing or in a a 
short form BVT.
If you come for Sanity testing,This is also called tester
Acceptence testing.
This is to determine, Whether the supplied build is 
testable or not, 
So Smoke  Test -Build Verification Test(BVT)
   Sanity Test -Tester Acceptence Test(TAT)
these are the very first tests conducted by the testing 
team.
Also called as level -zero tests in STLC.

I dont understand why rajendra is always not satified with 
the answers of sujata....agreed that she doest gives to the 
point answer ..but you should encourage her man

Smoke Testing...testing the basic features of application 
are present with out any failure based on screenshot/FS 
document.

Sanity Testing:Testing...Basic functionalities..(check 
box..list box...buttons...etc.) are working or not...in an 
application.

Smoke Test is scripted wheras Sanity Test is unscripted.
Smoke Test is shallow and wide coving all arears but not in 
depth. 
Sanity Test is Narrow and deep. To check the particular 
module is working fine after changes (Form of regression 
Tesing)
Smoke test is like build verification test
Sanity test is to check application functioning acc to 
requirement.

thats a very gud answer Mr.Rajendra Prasad Reddy .. A good 
explanation indeed , appriciate ur effort ..

Sanity Testing:

     Sanity testing is initial level of testing efforts to 
determine if a new version of build is performing well 
enough and accepted it for further testing activity..

Smoke Testing:

     Smoke testig is initial build acceptance test. Here we 
atest the major functionalities of the build, if the some 
test is passed then it will goes for further testing 
activity...
