Python’s default arguments are evaluated once when the function is defined, not each time the function is called. This means that if you use a mutable default argument and mutate it, you will and have mutated that object for all future calls to the function as well. more details about this wrong usage here: http://docs.python-guide.org/en/latest/writing/gotchas/#mutable-default-arguments Closes-Bug: #1534974 Change-Id: Ia87abe0d020d7840dbf5f8a3063f057bab92c2ba

A fake server that "responds" to API methods with pre-canned responses.
|
|
|
|
All of these responses come from the spec, so if for some reason the spec's
|
|
wrong the tests might raise AssertionError. I've indicated in comments the
|
|
places where actual behavior differs from the spec.
