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

it is an end to end testing where testing environment is 
just like production environment..........

The definitions of end-to-end testing listed on this page
are very technical. We think end-to-end testing does not
only include systems but also the complete organization. In
order to understand whether a product or a software can be
offered as intended the complete production chain should be
tested, starting from a customer touchpoint until the very
end of a transaction.

End-to-end testing is a comprehensive testing process for 
systematically adding and testing new components in 
software systems, as well as end-user testing of the 
overall integrated system. It refers to user-level testing 
of component-based systems. 

Fully supporting end-to-end processes requires combining 
service-orientation which takes an engineering approach to 
reduce the gap between software requirements and 
implementation with model-driven design which addresses the 
same problem in terms of well-understood mathematical 
structures. It verifies that the integrated component works 
correctly as part of the overall system, and that the 
existing components of the system work as before. 

End-to-end testing approaches the system from both the 
functional side and the architecture side, thus combining 
black-box and white-box techniques. Both techniques are 
used in varying degrees for different testing needs.

E2E is the only test that demonstrates the working of the 
complete process and the fault handling in each sub-
process. Methodical and structured E2E testing will 
decrease the time and budget involved in UAT and 
Infrastructure.

E2E Testing is a System Testing and in a wider aspect its a 
system integration testing as well since E2E tests the 
integrity between different modules as well integrity with 
other systems. Isnt it??

It is nothing but, test the system functionaliy. 
A system Where Delivery functional original required is 
called as the End to End Testing

Befor UAT we will test complete system flow wise

It is end to end testing, where in testing environment is just 
similar to production environment.

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" refers to user level testing of 
component based systems where  application will be tested 
from one business flow end to another business flow end 
completely covering application's functionality, non-
functional features & UI features.

End-to-End Testing is when you take a process from the very
beginning all the way to the end – like accepting an order
from a customer and then processing that order all the way
through fullfilment, accounting and shipping.  This is
basically exercising an entire “workflow”.  Although System
Testing is similar, in System Testing you do not have to
complete the entire workflow but may exercise individual
interfaces one at a time.  However by the end of System
Testing most test environments will exercise (or should
exercise) an entire end-to-end test.

i read this on net only, and found usefull.

End-to-end testing involves ensuring that that integrated 
components of an application function as expected. The 
entire application is tested in a real-world scenario such 
as communicating with the database, network, hardware and 
other applications. 

For example, a simplified end-to-end testing of an email 
application might involve logging in to the application, 
getting into the inbox, opening and closing the mail box, 
composing, forwarding or replying to email, checking in the 
sent items and logging out of the application.

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

End to end testing means " it  is the part of system
testing, where we test the application in end user point of
view.
