<br><font color="#330000">modified to better suit the requirements of PGS

by way of an example. An incomplete UnitTest was provided for the <i>Range

<p>&nbsp; <a href="Range.html">Range Class</a>
<p>In order to provide a unit test for the <i>Range</i> class the
<i>RangeTestCase</i>
class was developed. This inherits from the
<i>TestCase</i> class which
is part of the UnitTest library.&nbsp; Within this class 4 methods are
provided for testing various components of the <i>Range</i> class. The
four methods are
<br>&nbsp;&nbsp;&nbsp; testEquality
<br>&nbsp;&nbsp;&nbsp; testWithin
<br>&nbsp;&nbsp;&nbsp; testRangeException
<br>&nbsp;&nbsp;&nbsp; testOverlap
<br>These methods are bundled together into a suite. The facility provided
by the TestUnit library is the <i>TestSuite</i> class.&nbsp; All of the
tests within this suite are run within a <i>TestRunner</i> object.
