 well as the module's name.
 This is needed so that the methods are recognized by the test driver as
 test methods.
 Also, no documentation string for the method should be included.
 A comment (such as
-\code{\# Tests function returns only True or False}) should be used to provide
+\samp{\# Tests function returns only True or False}) should be used to provide
 documentation for test methods.
 This is done because documentation strings get printed out if they exist and
 thus what test is being run is not stated.
