Testing
plays an important role in SDLC and it is very
crucial because in SDLC, testing improve reliability, performance and some
other factors that may require during this process. Here, I am writing post Role of Testing in SDLC with Importance
so that apart from role, you can also learn why testing is important in SDLC.
Role of Software Testing in SDLC – Software Development
Below are given some important roles that
are played by the testing in the development of software (SDLC)
1. One of the important role plays by testing in SDLC is that
it, examines code/program for discovering problems and errors early in the
system.
2. Another role is, testing always
simulating a system/application to perform a program operation.
3. Software Testing always evaluates the
capabilities of the code/program over entire products.
4. Another main role is that, testing
always helps in reviewing of requirements and design as well as executing the
code.
5. Testing is also important in measuring
system/application functionality and quality of the product/project.
6. Testing also plays important role in
lowering the maintenance cost of the software product/project.
7. It also helps in providing interaction
between development and users.
Importance of Software Testing in SDLC – Software Development Life Cycle
Software
Testing is considered as the one of the important and necessary phases in SDLC
because of the following reasons given below:
1.
Testing always helps to verify that complete software requirements are
implemented correctly or not, means it is implemented according to the defined
requirements or not.
2. Testing
definitely helps in identifying defects/bugs and ensuring they are
recognized/addressed before software deployment stage.
3.
Testing also demonstrates that software/application appears to be working
according to specifications and the performance requirements that have been
defined is also met.
4.
One of the main reason why testing is
important in SDLC is, testing always helps to verify proper integration and
interaction of each component in the system.
Important Note
As
you know Software Testing has become one of the crucial parts of development
and it is better to start testing from the very early development phase in
order to avoid future difficulty by correcting the bug/defect at the final/last
stage.
If
any defect/issue is found and fixed after development, then the cost of
correction will be much higher than the cost of fixing it at earlier stages of
development.
Conclusion
At
end we conclude, this is all I know regarding Role of Testing in SDLC and why Testing is Important in SDLC, but
