POHow can I get nose to find class attributes defined on a base test class?

Body
copied!<p>I'm getting some integration tests running against the database, and I'd like to have a structure that looks something like this:</p> <pre><code>class OracleMixin(object): oracle = True # ... set up the oracle connection class SqlServerMixin(object): sql_server = True # ... set up the sql server connection class SomeTests(object): integration = True # ... define test methods here class test_OracleSomeTests(SomeTests, OracleMixin): pass class test_SqlServerSomeTests(SomeTests, SqlServerMixin): pass </code></pre> <p>This way, I can run SQL Server tests and Oracle tests separately like this:</p> <pre><code>nosetests -a oracle nosetests -a sql_server </code></pre> <p>Or all integration tests like this:</p> <pre><code>nosetests -a integration </code></pre> <p>However, it appears that nose will only look for attributes on the subclass, not on the base class. Thus I have to define the test classes like this or the tests won't run:</p> <pre><code>class test_OracleSomeTests(SomeTests, OracleMixin): oracle = True integration = True class test_SqlServerSomeTests(SomeTests, SqlServerMixin): sql_server = True integration = True </code></pre> <p>This is a bit tedious to maintain. Any ideas how to get around this? If I was just dealing with one base class, I'd just use a metaclass and define the attributes on each class. But I get an uneasy feeling about having a metaclass for the test class, a metaclass for Oracle, and a metaclass for SQL Server.</p>
