END TO END TESTING – H2kinfosys
End
to end testing is a major type
of testing where entire software is tested from start to end. All the functionalities within the software,
their interfaces, external interfaces, interaction between the different
servers & systems are tested in the environment similar to real time.
End
to end testing confirms that the integrated components of the software
function as expected. The entire application is tested in a real world
environment like communicating with database, network, hardware and other
applications. End to end testing methodology is used to test the performance of
the application and whether the flow of an application is performing as
designed. Generally end to end testing is phase of software testing which not
only validates the software system but also checks the integration with external
interfaces. The purpose of software testing is to exercise a complete
production like environment. Along with software system it also checks the
batch or data processing through other upstream or downstream systems. End to
end testing is done usually after functional and system testing.
Why
we need end to end testing?
The
modern software systems are complex and are interconnected with each other. The
part of a system or the subsystem may be different in functioning from the
current system or may be owned by other company. If any one of the subsystem
fails then the whole system may collapse. This major risk can be avoided by
this end to end testing process. It verifies the complete system resource flow.
It increases the test coverage of various subsystems. It helps to detect with
various issues of subsystems and increase the confidence of any software
application.
The chief activities
involved in end to end testing are
·
The study of end to end requirements
·
Test environment is set up with hardware and software
requirements
·
The systems and subsystems processes is described
·
Roles and responsibilities of all the systems are explained.
·
Testing the methodology and its standards
·
End to end requirement tracking
·
Input and output data of each system
1.
System testing:
Testing the whole system all
components of the system is functioning as expected. For example in e-commerce
website browsing items, cart and check out.
2. End to end test:
Here the actual workflow of
a system is tested. Can a user navigate through the applications and does it
work. It uses the exact production like data and the test environments to
simulate the real time settings. It is also called as chain testing.
For example consider a
situation where you login into your bank account and want to deposit some
amount to another bank account which becomes third party subsystem. You follow
the below steps
1. Logging
into the bank system
2. Check
the balance amount
3. Deposit
some money to another bank from your account
4. Check
your latest balance
5. Check
out from your account
Following activities are
done for testing build conditions like
·
Building a set of conditions for all the functions defined
·
The conditions which include data conditions, sequence and
timing
End to End testing is a
process of verifying the software system with its subsystems or parts. Here
having the knowledge of whole system as well as interconnected subsystems is
must.
