The newly deployed code is rechecked in order to ascertain the impact of updations, modifications or changes done to the code through the regression testing method. The features and functions of a product are tested in order to ascertain whether the product is built according to the product specifications through the functional testing method. In this article, you will know about the differences between regression testing and functional testing.
What is Regression testing?
It is a testing
method that ensures that the modifications, updations or changes done to the
code don’t affect the existing functionalities of the software application. Already
executed test cases that are partially or fully selected are re-executed to
ensure that the existing functionalities work just fine. Whenever the
requirement arises for making changes in the code, the modified code needs to
be tested in order to ensure that other parts of the software application are
not affected.
What is Functional testing?
It is a testing
method where a software application or system is tested against the
specifications and functional requirements. Each function of the software
application is verified in order to confirm whether the application works
according to the specified requirements or not. Appropriate input is provided
to every function of the software application so that the output can be
verified against the functional requirements.
Through the application of functional testing, Client/server communication, security, database, APIs, User Interface and other functionality of the application under test are checked. QA teams implement the platform of functional testing to ensure that a certain section of the software is in line with pre-determined requirements.
Difference between regression testing and functional testing:
|
Regression
testing |
Functional
testing |
|
It is not feature specific |
It has limited scope and is feature
specific |
|
It is focused on testing a product
end-to-end |
It is focused on testing every function
of the software application |
|
This testing method focuses on fixing the
software product issues and ensure that the code is working as expected |
This testing method focuses on the
working of a feature |
|
Acceptance criteria of several features
are focused upon, instead of just one feature that was added, updated or
fixed |
Testing is performed to ensure that the
features are working as per the required expectations |
|
The purpose of this testing method is to
ensure that the updated code did not have any adverse effects on the existing
functionalities of the software application |
The purpose of this testing method is to
perform a microscopic examination on a specific code or functionality in
order to make sure that a standard quality is maintained |
|
A developed product is tested on a
continual basis focusing only on those areas that have been updated |
Individual modules or functionalities as
a whole are tested |
|
When the code is being manipulated and
the issues are being repaired, this testing method is performed |
When a system is being described and it’s
working and functions are determined, this testing method is performed |
