What both publish
| Fact | Cosmic Ray | MuJava |
|---|---|---|
| Intended users | The documentation presents Cosmic Ray for Python projects whose teams want to check whether their test suites meaningfully verify code behavior. | The maker describes MuJava as a service to the community and says it has been used by students and researchers. |
| License | The project repository identifies the software as MIT licensed. | The project was released as open source under the Apache license in April 2015. |
| Purpose | Cosmic Ray is a mutation testing tool for Python 3 that makes small changes to production code and runs the test suite against each change. | MuJava automatically generates mutants for Java programs for traditional method-level and class-level mutation testing. |

Pick Cosmic Ray if…
Cosmic Ray suits Python teams who want to check whether their tests detect behavioral changes, rather than relying only on line execution coverage. It is particularly relevant where teams can configure and run potentially lengthy test suites.
Pick MuJava if…
MuJava suits students and researchers working on Java class or package testing with JUnit. It may also fit users comfortable with manual setup and reviewing equivalent mutants.
