Regression
testing plays a significant role in the software development process because it
ensures that the new code that has been introduced does not impact the existing
functionalities of the software product or application. When a specific feature
or module is introduced, updated and changed, regression testing is carried out
to ensure that the software product or application is functioning as expected.
Regression testing also makes sure that the new changes that have been
introduced or new features that have been added are also functioning as
expected. There may be a probability of code incompatibility issues because
testers and developers frequently strive to identify every thread of code. For
this purpose, regression tests are run so that bugs can be found earlier and
software can be released with fewer risks. In this article, you will get to
know the need to conduct software regression testing.
What is regression testing?
It is a
testing method that helps developers and testers effectively handle the changes
or modifications introduced in the code without compromising the overall
quality and efficiency of the software product or application. All the software
areas are strategically measured by software regression testing to make sure
that the functionalities and features remain unaffected by program or code adjustments.
The following are different types of regression testing:
1. Bug regression: The success
of fixes or patches to defects is confirmed through this type of regression testing
2. Conversion testing: The
application's state is validated through conversion testing after it has been
transported to another platform
3. Build Verification: Sequential,
small testing is used by testers to confirm whether or not a build has been
irreparably damaged.
Following are a few key reasons that depict the need to carry
out regression testing:
1. Defects are checked accordingly:
Software regression testing can be used by developers in QA assessments to
verify if there are any adverse issues in the software. For example, a video
game developer might use the regression testing method to assess any glitches,
bugs or issues after a new gaming code has been introduced into an application.
If the program has been identified with issues or bugs, the developer can go
back and make the necessary changes before the application is retested again to
make sure the issues have been fixed.
2. The value of retesting: Additional
test executions are provided by the regression test method to make sure the
viability of changes that have been made to the program codes. When each case
has been retested after a software change or update, it allows developers to
scrutinize how the changes that have been made recently affect the program. For
example, right after new program codes have been initialized, the software
program is tested by a software developer and then finds out that the existing
features are disabled by new features. Retesting is used by the developer each
time a change or repair is made to the update.
3. The existing functionality should be maintained properly:
Regression testing makes sure that any new program or code updates to software
do not interrupt the current features of the code. When a program or
application is being updated, regression testing is performed to evaluate the
viability of new features.
4. Assessing the new programming code:
The success of implementing new code into the existing code or program is
evaluated by the regression testing method. The software program can be tested
accordingly before the new code is implemented through the regression test
method. The same software can be retested by the regression test method to make
sure that the application's functionality is retained even when new code has
been introduced in the software application.
