JAllele
JAllele is a mutation testing tool for Java. By design, all mutants generated are valid and it aspires to avoid equivalent mutants.
Here is the origin for the project’s name:
http://en.wikipedia.org/wiki/Allele
Status
Current status of the project is described in bytecode mapping. Currently implemented bytecodes display the corresponding handler.
An initial run will determine a list of all possible mutations. The actual mutation run will choose one of the previously identified mutations to validate that the unit test bed detects that change.
The “strength” of the test bed can be expressed as percentage of the mutation runs failed over the number of mutations runs.
Usage
Currently a command line access is made available. The libraries have to be built, as they are not yet published to a Maven repository.
$ ./gradlew build
Run JUnit sample (packaged into uberjar):
$ java -jar jallele-cmdline/build/libs/jallele-cmdline-test-*.jar --count 10 \
--sources com.github.gliptak.jallele.SimpleClass --tests com.github.gliptak.jallele.SimpleClassJUnitTest
Run TestNG sample (packaged into uberjar):
$ java -jar jallele-cmdline/build/libs/jallele-cmdline-test-*.jar --count 10 \
--sources com.github.gliptak.jallele.SimpleClass --tests com.github.gliptak.jallele.SimpleClassTestNGTest
