Some Important Techniques For Regression 
Testing That You Must Know


The kind of software testing method that is performed after the implementing new features or modifying of the
existing functionality is called regression testing. Its purpose is to make sure that all changes to the code do not
evoke any side effects and interrupt the exact operation of the whole system and its components.

Regression testing services are also done after certain flaws have been corrected. It is done for checking that
the problems have been fully removed. Besides that, the process of flaw fixing should not affect anyhow the
existing functionalities.


To effectively perform the process of the software product after any corrections or modifications, the many techniques can
be implemented.

• Prioritization of test cases
• Test selection
• Retest all

The process of retesting all designed test cases in the suite is rather cost-intensive and time-consuming as it needs much
hard work and resources. If the deadline is coming, then this technique will not effect.


Automated Regression For Faster Turnaround

Teams required to make sure an effective balance between quality and speed, which means they require faster and credible
feedback. Especially in an agile environment, it is essential that the feedback comes in faster, so that the essential action is
needed.


No Tolerance For Flaws

There is minimal or no scope for errors during constant releases in an agile set-up. Each code issued in
production requires to perform and give results as required and improve the user experience.

With regression tests, the software is made resistant to flaws even in the longer run, dedicating testing teams to
release faster with quality assurance. At every level of release, the application/software is tested for defects and
bugs, adopting a zero-tolerance policy towards flaws.


Adding New Functionalities

Businesses require to innovate and try new methods
to improve the user experience. This means that
during an application development procedure, there
has to be full scope of introducing new
functionalities and testing them for useful
integration with the other features of the
application.

Regression tests normally are initiated when a
programmer fixes flaws or adds codes for new
functions for the system. There can be a lot of
dependence on recently added and existing
functionality. To make sure quality, it is necessary to
check that the new code works together with the old
code and the unmodified code is not changed.

Often, regression testing is done through various
phases of testing. It is for this purpose, that there are
various types of regression testing services.


Complete Regression – Complete regression testing is usually carried out when the code changes for
modification or the software features seep way back into the roots. It is also taken out in case there are many
changes to the present code. It provides a complete view of the system as a whole and weeds out any
unforeseen issues. A sort of a “final” regression testing is executed to verify that the build (new lines of code)
has not been modified for a period of time. This final version is then deployed to end-users.
