2. Software testing is a long and multi-layer process which involves a lot of
development and probing for the software. Quality assurance and quality
management have never been as important as they are now.
So in order to test the quality, reliability, scalability and resource usage of a
software, they have to undergo software performance testing.
 Performance testing is a subset of performance engineering, an
emerging computer science practice which strives to build performance into
the design and architecture of a system, prior to the onset of actual coding
effort.

4. To ensure reliability, availability and stability of applications, enterprises
must focus on quality assurance. To achieve this, they need to build
dedicated teams that study the quality of the system in question.
 The solution is a robust framework that enables enterprises to establish
strong quality processes and is conducted in the (tcoe) testing center of
excellence in agencies.
TCoE is a centralized testing model that brings people and infrastructure
together into a shared services function for standardizing test processes,
optimizing utilization of resources and creating re-usable test assets /
repositories in order to generate enhanced benefits across the
organization.

5. Following performance testing, software are sent to a process which is
conducted to ensure that system requirements meet business needs.
 The process allows for any issues to be fixed before the system goes live. This
is called user acceptance testing. It may involve black-box testing performed
on a system like a piece of software, lots of manufactured mechanical parts, or
batches of chemical products prior to its delivery.
 It is the last phase of the software testing process. During UAT, actual
software users test the software to make sure it can handle required tasks in
real-world scenarios, according to specifications.
 There are many reasons why acceptances testing is important. One of the most
important being demo and stepping into the end users shoes. The unique angle
of user acceptance testing (UAT) is to test software as an end user.

7.  It does not focus on the cosmetic errors, spelling mistakes or system testing.
 This test is to be conducted in the final stage of Software Development Life
Cycle (SDLC) prior to system being delivered to a live environment.
User acceptance testing users or end users are concentrating on end to end
scenarios & typically involves running a suite of tests on the completed system
with production like data setup.
UAT is performed after System Testing is done and all or most of the major
defects have been fixed.
The main purpose of this testing is to validate the end to end business flow.
Software is built to give users tangible results. It tells you how usable the
system is as most user acceptance testing is based on is best performance by
software in real life
