loader

package-level fixture list

load_tests = FixtureLoader(['db', 'init'])

use of fixtures in tests

Besides setup-teardown functions, fixtures provide context to tests via attributes.

@contextmanager
def myfixture(test):
  yield {'my_resource': SomeResource()}

The dictionary returned in fixture's __enter__ method will be added to test class namespace.

parameters

The most common way should be defining parametrized fixture through inheritance:

class DbContext(Fixture):
  __key__ = 'db'
  
class PostgresqlContext(DbContext):
  pass

class ExcludeThis(DbContext):
  is_fixture = False

use of tests in fixtures

class MyFixture(Fixture):

  def __enter__(self, test):
    # `test`: probably, it should be not real test or test class instance but helper obj
    if should_skip(test):
       raise SkipFixture
