Plugins

So far, we have focused on using mock directly. However, there are many plugins that can help with mocking, such as pytest-mock, which, amongst other things, provides a mocker fixture. One advantage is that the fixture cleans up after itself, so you don’t need to use a with block, as we did in our examples. mocker.spy is also a handy simplification based on wraps and autospec.

There are also some specialised mocking libraries:

• For mocking database access, the following are suitable:

  • pytest-postgresql

  • pytest-mongo

  • pytest-mysql

  • pytest-dynamodb.

• To test HTTP servers, you can use pytest-httpserver.

• To mock requests, you can use responses or betamax.

• Other tools for various requirements are

  • pytest-rabbitmq

  • pytest-solr

  • pytest-elasticsearch and pytest-redis.
