+SNAPS Unit Testing
+==================
+
+| Tests designated as Unit tests extend the unittest.TestCase class and
+  can be exercised without any external resources
+| other than the filesystem. Most of these tests simply ensure that the
+  configuration settings classes check their
+| constructor arguments properly.
+
+The Test Classes
+================
+

+-  testFileIsDirectory - ensures that the expected path is a directory

+   False
+-  testFileExists - ensures that a file that does exist returns True
+-  testDownloadBadUrl - ensures that an Exception is thrown when
+   attempting to download a file with a bad URL
+-  testCirrosImageDownload - ensures that the Cirros image can be
+   downloaded
+-  testReadOSEnvFile - ensures that an OpenStack RC file can be properly
