| Spec score · Mutation Testing Tools | 8.4 (#3) | 6.5 (#25) |
| Installation | The documented setup uses two JAR files and a configuration file, and requires configuring Java CLASSPATH and PATH. | The README instructs users to install the `cargo-muttest` Cargo plugin and add `muttest` to their crate. |
| Intended users | The maker describes MuJava as a service to the community and says it has been used by students and researchers. | The documented setup is for Rust crate developers who want to assess how well their tests detect code changes. |
| License | The project was released as open source under the Apache license in April 2015. | The repository includes an MIT license that permits use, copying, modification, distribution, sublicensing, and sale subject to its terms. |
| Purpose | MuJava automatically generates mutants for Java programs for traditional method-level and class-level mutation testing. | muttest-rs is a Rust mutation testing tool for evaluating whether a test suite catches simulated bugs. |

In their own words
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.
