Subject: Add test to as_interface when no cls or methods
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F4512%2Fhead;p=thirdparty%2Fsqlalchemy%2Fsqlalchemy.git

Add test to as_interface when no cls or methods

The `as_interface` function requires that an argument be provided for at least one of the parameters `cls` or `methods`. There was no test that tested the case when neither of these arguments were provided.
