The SigTest open source project is a collection of tools based on Oracle’s commercial SigTest tools product. The SigTest tools can be used to compare APIs and to measure the test coverage of an API.

The tools were originally created to assist in the creation of Java technology compatibility test suites (TCKs), but are also useful in the creation of other types of test suites and in the software development process.

With SigTest 2.2, we are expanding the SigTest project to include other tools based on the same signature testing technology as the SigTest to itself. SigTest now includes API Check tool functionality, a static analysis tool used to analyze APIs. SigTest 2.2 also adds Maven wrappers, as well as support for upcoming JDK 8 features. SigTest also includes numerous bug fixes.

The SigTest project continues to develop a community that will improve it, further its development, and use it to develop test suites. We encourage you to browse, download, contribute, and get involved.
