10 Most Robust Mutation Testing Tools For Successful Software Testing
Mutation testing is one of the crucial testing methods in the process of software development. It is a part of white box testing, in which the major focus on making changes to test suits to ensure that the test suite can efficiently detect errors in the source code. The main purpose of mutation testing is to detect errors or bugs in the software and fix them in a timely fashion. Moreover, this test is conducted at the software development phase, unlike regression testing, which is conducted post-delivery.
Here is our rundown of some of the best mutation testing tools that you can used to test your software prior to delivering it your client. Read on!
