XMLUnit 2.x Development Moved to GitHub XMLUnit provides help with testing code that creates or consumes XML. XMLUNit 2.x is available for both Java and .NET with a similar API. Development of this version has moved to a GitHub organization with two git repositories for Java and .NET respectively. All discussion about XMLUnit independent of any version will happen on the XMLUnit general mailing list. XMLUnit for Java 1.x will still be maintained using the Sourceforge infrastructure that has served as well for many years. We don't intend to maintain XMLUnit for .NET 0.x any longer.  https://github.com/xmlunit  https://sourceforge.net/p/xmlunit/mailman/xmlunit-general/
