This function creates and saves a default test method for a RTest adapter with predefined arguments (see 'Details'). It will automatically create the generic as well as the method for the test case class using S4 style.
setTestMethod(f, signature = "RTestCase", definition = function(object,
  inputData, execCache, xmlDef, ...) NULL, where = parent.frame())(character) The name of the function.
(character) The name of the corresponding test case adapter
(i.e. the name of the class, which inherits 'RTestCase' and implements
all functions associated to a test case type and specifications).
(function) The method, which will be called if the signature
matches the definitions (see 'Details').
(env) An environment where to set up the Method
This function is a wrapper for standardized and simplified creation of S4-syle test case
adapters required for RTest. The passed function has to be assigned to the corresponding test
case class, whichinherits RTestCollection-class) and represents the adapter for
the respecive implementation of a test case type (i.e. XSD scheme). The passed function
definition has to be in the following format with the following parameters.
function(object, inputData, execCache, xmlDef, ... ) {
  # implementation goes here
}
object(object) The RTestCase-class object.
inputData(list) List with all input data provided in the XML test case.
execCache(list) List with cached results determined in the predecessor
    test functions of a test case execution.
xmlDef(XMLNode) An object of class XMLNode, which defines the
    current test function.
...Additional parameters passed to the individual test functions.
