MuJava

MuJava is a tool used by software developers to automatically test Java programs for errors. It works by creating small modifications—called mutations—of the original code, then checking if the program’s tests can detect these changes. This process helps identify weaknesses in test cases and ensures the program behaves correctly. Essentially, MuJava helps improve software quality by systematically challenging the code to catch potential bugs or flaws, making programs more reliable and robust.
