"""Support classes and functions for the elpy test code.
|
|
|
|
Elpy uses a bit of a peculiar test setup to avoid redundancy. For the
|
|
tests of the two backends, we provide generic test cases for generic
|
|
tests and for specific callback tests.
|
|
|
|
These mixins can be included in the actual test classes. We can't add
|
|
these tests to a BackendTestCase subclass directly because the test
|
|
discovery would find them there and try to run them, which would fail.
