/**
* Collection of static methods so that XML assertion facilities are available
* in any class, not just test suites. Thanks to Andrew McCormick and others for
* suggesting this refactoring.
* Available assertion methods are:
*
*
assertXMLEqual
* assert that two pieces of XML markup are similar
*
assertXMLNotEqual
* assert that two pieces of XML markup are different
*
assertXMLIdentical
* assert that two pieces of XML markup are identical. In most cases
* this assertion is too strong and assertXMLEqual is sufficient
*
assertXpathExists
* assert that an XPath expression matches at least one node
*
assertXpathNotExists
* assert that an XPath expression does not match any nodes
*
assertXpathsEqual
* assert that the nodes obtained by executing two Xpaths
* are similar
*
assertXpathsNotEqual
* assert that the nodes obtained by executing two Xpaths
* are different
*
assertXpathValuesEqual
* assert that the flattened String obtained by executing two Xpaths
* are similar
*
assertXpathValuesNotEqual
* assert that the flattened String obtained by executing two Xpaths
* are different
*
assertXpathEvaluatesTo
* assert that the flattened String obtained by executing an Xpath
* is a particular value
*
assertXMLValid
* assert that a piece of XML markup is valid with respect to a DTD: either
* by using the markup's own DTD or a different DTD
*
assertNodeTestPasses
* assert that a piece of XML markup passes a {@link NodeTest NodeTest}
*
* All underlying similarity and difference testing is done using
* {@link Diff Diff} instances which can be instantiated and evaluated
* independently of this class.
* @see Diff#similar()
* @see Diff#identical()
