""" Post-Test Hook: ExpectedRetCode
This is a post-test hook which checks if the exit code of the Wget instance
under test is the same as that expected. As a result, this is a very important
post test hook which is checked in all the tests.
Returns a TestFailed exception if the return code does not match the expected
value. Else returns gracefully.
