First, the test must be collected in a testsuite, and the testsuite must then be run. A testsuite is a collection of related tests, of the type <TTCLASS="CLASSNAME">TestSuite</TT>.</P><P>It is customary to create a function <TTCLASS="FUNCTION">suite()</TT> in every testfile that return a suite with all the tests the file contains. This function is then called by a <TTCLASS="CLASSNAME">TestRunner</TT> object. This will be either a <TTCLASS="FUNCTION">TextTestRunner</TT>, if you run your tests without a gui, or a gui TestRunner application, such as the <SPANCLASS="APPLICATION">QtTestRunner</SPAN>. Defining a testsuite is a simple matter of creating a <TTCLASS="CLASSNAME">TestSuite</TT> object and adding tests: </P><PRECLASS="PROGRAMLISTING">def suite(): testSuite=unittest.TestSuite() testSuite.addTest(DocviewDocTestCase()) return testSuite </PRE><P>In order to be able to execute this file it's handy to add a bit of executable code to the end:</P><PRECLASS="PROGRAMLISTING">def main(): runner = unittest.TextTestRunner() runner.run(suite())if __name__=="__main__": main() </PRE><P>Running the test will give you the satisfaction of knowing that at least one piece of your application is working:</P><PRECLASS="SCREEN">boud@calcifer:~/doc/pyqt > python ch9/dvt1.pyrunTest (__main__.DocviewDocTestCase) ...ok------------------------------------------------------------------------------Ran 1 test in 0.035sOK </PRE><P>Or, if you want to see the green and pleasant bar, you can run the gui testrunner.

Please note that the actual output you get might differ. The python unittesting framework is in constant development.
