Why is configuration testing necessary?

Configuration testing is a technique for testing a system or software under development on various machines that
have various configurations and combinations of software and hardware. The performance of the framework or
an application is tested against each of the software configurations and supported hardware.

As discussed, this testing is a strategy that evaluates the presence of a product, framework/application thinking
about the different system configurations.

This testing is done to decide the ideal setups under which a framework or an application can work fine with no
bugs, issues or flaws in execution. So, the most strong setup that will convey the necessary execution attributes
is spotted with the assistance of this testing. 

The subsequent primary purpose behind this testing is to check the framework's similarity with the other
programming or hardware implied in the SRS (software requirement specification).

Steps to complete configuration testing

#1) Preparing the Coverage Matrix

#2) Prioritizing the Configurations

Types of Configuration Testing 

Software configuration Testing

This testing is done over the AUT (application under test) with various OS adaptations, programming
refreshes, and so on. This is lengthy testing as it expends an immense time to introduce and uninstall
the different programming which is to be utilized for testing. 

Hardware configuration testing

Hardware configuration testing is typically completed in labs, where we have physical machines with
different equipment associated with them.

Conclusion

Configuration testing is as significant as some other programming testing type as it finds the ideal
design of the framework under which the application performs at its best. Additionally, it helps in
distinguishing and rectifying any similarity issues.
