If you have to maintain a massive project, you probably have many fixtures in conftest file. And there is a problem; this file grows and grows. So, at some point, you decide to split this huge file into smaller files. But, py.test has to know the fixtures are keeping in these files. So, what you can do? I see three patterns here for this: import these guys inside conftest.py file create more conftest.py files use pytest_plugins Import fixtures inside conftest file You can for example do this: 1 2 3 4 5 6 7 8 9 from tests.my_fixtures.fixs1 import ( fix11, fix12, fix13, fix14, fix15, ... ) from tests.my_fixtures.fixs2 import ( fix21, fix22, fix23, ) from tests.my_fixtures.fixs3 import ( fix31, fix32, fix33 ) But, there are some problems with this approach. You import them in an explicit way, so if you create a new fixture, you have to remember to add this guy in the import clause. So, this strategy is not the best solution. If you have many fi...

pytest-dbfixtures If you use pytest maybe you have heard about pytest-dbfixtures : Pytest dbfixtures is a pytest plugin that makes it a lot easier to set up proper database or storage engine for testing. Simply use one of provided fixtures that start predefined clean database server for your tests or creates server more tailored for your application by using one of provided factories.

Currently, the plugin supports: Postgresql MySQL Redis Mongo Elasticsearch RabbitMQ And recently, we have added support for DynamoDB . Here , you will find how to run DynamoDB on your computer. And, here we are. If you want to use it in production, you want to test it locally. dynamodb fixture If you still do not use pytest, go to the pytest page and read how to use it, now.
