AS their name indicates
Smoke Test means: Build Verification Test(BVT)
                  checking the Build is stable or not.
Sanity Testing: Tester Acceptence Test(TAT)
                Checking the given Build is testable or not
                That means checking all features are  
                working and accesssible or not.
But one thing In most of the testing companies  even in Some
Big MNCS  the above two are considered as same.

After getting the build, first we will be doing sanity 
testing to conform whether the given application is able to 
carry for further testing.

Smoke testing is that after completing the whole testing of 
the build, we will be checking the build is stable or not.

a)	In smoke and sanity 1st conducting the sanity 
testing.
b)	Sanity testing is nothing but whether the 
development team release build is a, is table for complete 
testing or not test is called the sanity testing.
c)	That is the build start to end is possible, no 
middle brakes, if some navigation after the build and with 
system hang or not this types of tests
d)	This sanity testing also is called the Tester 
acceptation testing (TAT) or build verification test (BVT) 
e)	This test is monitory test also
f)	Now smoke testing is nothing but it is a small 
change a in a sanity testing process.
g)	That is in above (in sanity testing) what test are 
conducting now the tester if any problem arise then in 
tests, then reject build with reasons, build is not working 
it is called the smoke testing.
h)	Smoke testing is also known as the optional testing 
also.
i)	Actual it the both process but now the MNC 
companies are follow the when the problem arise, (remember 
it not test execution it is only 1st build verification 
test only) then stop the test on the build the intimate the 
developments team.
j)	So all are doing smoke testing only that here 
verify and intimate also.

Smoke Testing: in which one can perform initial an short 
span testing conducted on the application to check if all 
the required windows/features/objects are basically 
available in order to carry on the detailed testing on 
it.So the smoke testing is referred as availability testing.

Sanity Testing: it is also same as Smoke testing, but it 
checks for proper availability.

Hey please dnt give wrong answers ...

whenever a build is released first of all we do smoke 
testing to check whether the build is ready to take further 
testing.its just to check the major funtionality ..

Sanity testing is in depth testing which cover all the 
major and minor functionality of a project..

for e.g let to check module A , B , C is called smoke 
testing than in depth testing of these modules like in <A> 
a1,a2,a3.. than in function <B> b1,b2,b3 ,i mean in depth 
testing of major functionality,is called sanity testing..

in sanity we dnt need to execute test cases..

smoke testing - build verification test
which is done by release engg team near develovpement 
enviroment
sanity testing- done by qc testers near deployment
