RecGen

RecGen is a random unit-test generation tool with MUT-aware sequence recommendation. RecGen automatically creates unit tests for Java classes, in JUnit format.

Documentation

A short paper Random Unit-Test Generation with MUT-aware Sequence Recommendation explains the basic idea, the algorithm, the implementation, and the experiments.

Source Code

• RecGen.zip

We have tested RecGen with Eclipse 3.4 under Ubuntu 9.04 and Windows XP.

Evaluations

We have evaluated RecGen on three subject programs.

• Berkeley DB (v3.3.87): a database library
• JDSL (v2.1.1): a data structures library
• JScience (v4.3.1): a science computation library

The resulting test suites generated by RecGen and other three random testing tools (JCrasher, Randoop, and ARTGen) are as follows.

• The test suites generated on Berkeley DB
• The test suites generated on JDSL
• The test suites generated on JScience

Please refer to the short paper for the summary of the code coverage results.
