| Installation | The guide documents installation with `cargo install --locked cargo-mutants`, `cargo binstall`, or binaries from GitHub releases. | The documented setup uses two JAR files and a configuration file, and requires configuring Java CLASSPATH and PATH. |
| Purpose | cargo-mutants is a mutation testing tool for Rust that finds places where bugs could be inserted without causing tests to fail. | MuJava automatically generates mutants for Java programs for traditional method-level and class-level mutation testing. |
| Support | The project README invites users to share experience reports in GitHub Discussions and sponsor development. | The maintainers offer MuJava as-is and do not guarantee question answering, fault fixing, or improvements. |

MuJava
MuJava is a free, open-source tool for mutation testing of Java programs. It generates mutants for individual classes and packages, using 24 class-level operators as well as method-level operators, then runs tests against those mutants and evaluates mutation coverage. Tests must be JUnit test cases with public test classes and methods that call the classes under test; JUnit test suites are not supported. Equivalent mutants require manual identification, and the documentation says they typically make up 5% to 20% of mutants. Version 4 supports Java 1.6 language features, including generics, annotations, enumerations, varargs, enhanced for-each loops and static imports. Setup uses two JAR files and a configuration file, with Java CLASSPATH and PATH configuration. The documented workflow uses Java GUI applications; a command-line interface called muScript was released in March 2014, and an Eclipse plugin was created in 2007. The project is provided as-is, without guarantees of answers, repairs or improvements. It is available for Linux, macOS and Windows.
