nu.xom.tests contains the JUnit based test suite for XOM. The XOMTests class runs all the tests. Some of the tests, especially the builder tests, are dependent on the underlying parser, and are known to fail if the parser is buggy. Xerces 2.1.0 is the only parser which is currently known to be able to run all the tests. Earlier versions of Xerces 2.x, including the one bundled with the JDK 1.4, cannot successfully run all the tests.
