Comment(by reganeet):

 Hi Damian,

 I've written the unit test and pushed into my repo:
 https://github.com/beckbaibai/stem

 In the test file for server descriptor, I added the correct fingerprint
 into RELAY_DESCRIPTOR_ATTR, and test_minimal_relay_descriptor() will now
 check if it has been read correctly. Another test case,
 test_fingerprint_malformed(), is added to make sure the construction will
 fail if the fingerprint does not match the signing key.

 Notice that after the second part of the validation is implemented,
 testing would become more complicated, because the signature has to match
 the hash of the content, and signed with descriptor's signing key (the
 private one).

 I think I've merged my branch with yours in the right way...but please
 double check since I'm still not comfortable with git merge.

 Thanks!
 Beck
