pytest-dynamodb

Package status

What is this?

This is a pytest plugin, that enables you to test your code that relies on a running DynamoDB Database. It allows you to specify fixtures for DynamoDB process and client (resource in AWS boto terms).

How to use

Plugin contains two fixtures

• dynamodb - it’s a client/resource fixture that has functional scope. After each test it drops tables in DynamoDB.

• dynamodb_proc - session scoped fixture, that starts DynamoDB instance at it’s first use and stops at the end of the tests.

Simply include one of these fixtures into your tests fixture list.

You can also create additional dynamodb client and process fixtures if you’d need to:

from pytest_dynamodb import factories

dynamodb_my_proc = factories.dynamodb_proc(
    port=None, logsdir='/tmp', delay=True)
dynamodb_my = factories.dynamodb('dynamodb_my_proc')

Configuration

You can define your settings in three ways, it’s fixture factory argument, command line option and pytest.ini configuration option. You can pick which you prefer, but remember that these settings are handled in the following order:

• Fixture factory argument

• Command line option

• Configuration option in your pytest.ini file

Example usage:

• pass it as an argument in your own fixture

  dynamodb_proc = factories.dynamodb_proc(
      port=8888)

• use --dynamodb-port command line option when you run your tests

  py.test tests --dynamodb-port=8888

• specify your port as dynamodb_port in your pytest.ini file.

  To do so, put a line like the following under the [pytest] section of your pytest.ini:

  [pytest]
  dynamodb_port = 8888
