VisitMuJava vs PIT
What both publish
| Fact | MuJava | PIT |
|---|---|---|
| Language support | Version 4 supports Java 1.6 language features including generics, annotations, enumerations, varargs, enhanced for-each loops, and static imports. | The FAQ lists Java as supported and says Kotlin support is available through an ArcMutate plugin. |
| Mutation operators | It creates object-oriented mutants using 24 class-level operators and also supports method-level operators. | PIT applies configurable bytecode mutations, including removing method calls, inverting logic, and altering return values. |
| Purpose | MuJava automatically generates mutants for Java programs for traditional method-level and class-level mutation testing. | PIT runs unit tests against automatically modified versions of application code to measure whether tests detect faults. |
| Support | The maintainers offer MuJava as-is and do not guarantee question answering, fault fixing, or improvements. | PIT directs users to its Google Group for support questions. |
