Development Resources/TCK Access
Many organizations provide Technology Compatibility Kits (TCKs) that specification implementers can use to validate their implementation. The TCK is--essentially--a battery of tests that, when run against software can be used to claim compliance with the specification.
Like all software, TCKs are made available under license. In some cases, a fee must be paid to either gain access to the TCK itself, make claims about the results of the tests, or to claim certification. Naturally, we expect Eclipse projects to observe the terms of the license.
