Reusing test code with fixtures

The first thing we should do is to extract the desired functionality into well-defined fixtures and put them into a conftest.py file. Continuing with our example, we can create db_testing and gui_testing fixtures:

class DataBaseFixture:    def __init__(self):        self.db_file = self.create_temporary_db()        self.session = self.connect_db(self.db_file)    def teardown(self):        self.session.close()        os.remove(self.db_file)    def create_temporary_db(self):        ...    def connect_db(self, db_file):        ...    [e-mail] db_testing():    fixture = DataBaseFixture()    yield fixture    fixture.teardown()class GUIFixture:    def __init__(self):        self.app = self.create_app()    def teardown(self):        self.app.close_all_windows() def mouse_click(self, window, ...
