XMLUnit extends NUnit and JUnit to enable unit testing of XML.

XMLUnit compares a control XML document to a test document or the result of a transformation, validates documents, and compares the results of XPath expressions.

XMLUnit for Java provides two JUnit extension classes, XMLAssert and XMLTestCase, and a set of supporting classes (e.g. Diff, DetailedDiff, Transform, SimpleXpathEngine, Validator, NodeTest) that allow assertions to be made about:
· The differences between two pieces of XML
· The outcome of transforming a piece of XML using XSLT
· The evaluation of an XPath expression on a piece of XML
· The validity of a piece of XML
· Individual nodes in a piece of XML that are exposed by DOM Traversal

XMLUnit for Java can also treat HTML content (even badly-formed HTML) as valid XML to allow these assertions to be made about the content of web pages too.

Requirements:

· Junit (a JAXP compliant XML SAX) and DOM parser (a JAXP/Trax compliant XSLT engine) in your classpath

What's New in This Release: [ read full changelog ]

· The major new feature of XMLUnit for Java 1.2 is an alternative XML
· validation subsystem built on top of JAXP 1.3 which supports
· validation against alternative XML Schema languages - if your JAXP
· implementation supports them - and validation of the Schema definition
· itself.
· In addition all known issues of XMLUnit 1.1 have been fixed, for a
· more comprehensive list see
