ConTeGe

ConTeGe (short for Concurrent Test Generator) is a framework for generating sequential and concurrent unit tests. It is a research platform to build tools for finding correctness and performance problems in sequential and concurrent Java classes. In particular, ConTeGe is the basis for the following approaches:

An automatic and precise thread safety checker that found previously unknown bugs in the JDK

See thread-safe.org for details.

An approach for automatic substitutability testing that finds various bugs in widely used Java classes

SpeedGun, a performance regression testing tool for thread-safe classes

Instructions for running ConTeGe

To run a pre-built version equivalent to the PLDI'12 paper, run the following from the ConTeGe direcory:

./scripts/ClassTester_pre-built.sh

It will test the XYSeries class from the benchmarks directory and (hopefully) find a thread safety violation after a few seconds. To test other classes and run more benchmarks, see the comments in this and the other scripts.
