SigTest tool is based on Sun Microsystem's SigTest API conformance tool. SigTest tool makes it possible to easily compare the signatures of two different implementations of the same API. It verifies that all of the members are present, reports when new members are added, and checks the specified behavior of each API member.

Originally developed to help in the creation of TCK test suites, it has since evolved into a general purpose tool that can be used to compare any two implementations of an API to determine their differences. This functionality can be extremely useful during the application development process because it allows developers and quality testers to track the evolution of their products.

The SigTest project is being created in order 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
