Mutation testing is a fault based technique which helps to evaluate the performance of test suites. The effectiveness of test suites are measured by how many faults are detected.

The tools which are used to perform experiments are Judy, Major and PIT. These tools are freely available and used frequently. In this study, we will focus on these tools.

Major is also a tool that is mostly used in studies. Major tool is integrated into the Java Compiler, therefore, it can be used in any Java-based environments. The process of generating mutant is that it manipulates the abstract syntax tree of component which is going to be tested. It is also known as conditional mutation analysis tools.

MAJOR has a DSL support for specifying and adapting mutation operators. This makes Major extensible for mutation operators.

Judy is an implementation of the FAMTA Light approach developed in Java with AspectJ extensions.
