/**
 * 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() */ public class XMLAssert extends Assert implements XSLTConstants { protected XMLAssert(){ super();
