However, this is not tested due to too many-     corner cases for special parsers that don't take arbitrary-     Strings.  As the Dot standard is ambiguous over whether you can-     or can't use numbers as Strings (more specifically, if they-     should be quoted or not), this is a user beware situation.--   * Same goes for empty Strings; sometimes they're allowed, sometimes-     they're not.  Thus, to simplify matters they're not generated.--   * The generated Strings are very simple, only composed of lower-     case letters, digits and some symbols.  This is because too many-     tests were \"failing\" due to some corner case; e.g. lower-case-     letters only because the parser parses Strings as lowercase, so-     if a particular String isn't valid (e.g. @\"all\"@ for 'LayerID',-     then the 'Arbitrary' instance has to ensure that all possible-     ways of capitalising that String isn't generated as a random-     'LRName'.--   * The generated 'DotRepr's are not guaranteed to be valid.--   * To avoid needless endless recursion, sub-graphs do not have their-     own internal sub-graphs.--   * This test suite isn't perfect: if you deliberately try to stuff-     something up, you probably can.--}-module Data.GraphViz.Testing-       ( -- * Running the test suite.-         runChosenTests-       , runTests-       , runTest-
