End to End testing is also called system testing. Done by 
Senior test engineers or Test lead.

end to end testing is nothing but system testing..testing 
the application starting from scratch to the end after 
integrated all the modules.....

end to end testing or inter system testing :
  example :  E-seva

end to end testing is nothing but inter system testing. if 
our application should share the data with other similar 
applications ,testing whether it is coordinating properly 
with other applications is called end to end testing
ex-E-seva

Test the application from one end to another end at a time
is called End to End testing generally it is conducted
before closing the testing
This test is conducted to validate the flow of data between
modules
And know the behavior of the application
This is also part of the system testing

E2E is done after system integration testing as a 
successfull SIT is the entry criteria to start off with E2E.

E2E is almost like UAT with an exception that it is done by 
testers.Here we test the full flow for every business 
rules. A tester would give an input and straight away see 
the output. Generally a defect encountered in E2E is tough 
to fix as one would not know what caused it.Setting all the 
business rules appropriately and evaluating a system is 
nothing but E2E.

After Unit testing start to User Acceptance testing is done
this is End To End Testing.

To check wether our application bulid is coexstence with 
other application bulid or not.
 For ex we are using front end screen in java script and 
back end screen in sql, our apllication build support both. 

To check wether our application bulid is coexstence with 
other application bulid or not.
 For ex we are using front end screen in java script and 
back end screen in sql, our apllication build will support 
both. 

To validate one Application resources are using another 
application resources or not.

Example:Hotel Software,e-seva

Hi
it is inter system testing or interoparablity testing
To check our software coexistanece
with other software and share comon resourses or not
example banking

i am request every persion it is not game the number lifes
based inthis site please invove with interest

                thanks

A comprehensive type of testing that covers all stages in a 
testing process from start to release of the product.

End to end testing means from the staring point to end 
point of testing of one s/w build. all the user interface 
testing,functional testing & non-functional testing is 
comes under this end to end testing.

End-to-end testing is the process of testing transactions or
business level products as they pass right through the
computer systems. Thus this generally ensures that all
aspects of the business are supported by the systems under test.

regards
somu

it is a type of testing in which one will perform testing 
on the end to end scenarios of the application
   
  ex:login
     balance enquire
     withdraw
     balance enquire
     logout

Testing a complete application environment in a situation 
that mimics real-world use, such as interacting with a 
database, using network communications, or interacting with 
other hardware, applications, or systems if appropriate

End to End testing is finalise result of the project.
it's once again revision of the project
