# 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

* testCirrosImageDownload - ensures that the Cirros image can be downloaded
* testReadOSEnvFile - ensures that an OpenStack RC file can be properly parsed
