A set of tools for creating declarative docker py.test integration fixtures.
Project description
pytest-docker-tools
This package contains some opinionated helpers for Dockerized integration
testing drive by py.test.
You can define your fixtures in your conftest.py or in the test module
where you are using them.
A simple example of a container built from an image with a volume attached:
from pytest_docker_tools.factories import *
container(
'my_microservice',
image('my_microservice_image', path='.'),
volumes={
volume('my_microservice_data'): {'bind': '/var/tmp'},
}
)
Wherever possible the arguments to container_fixture mirror the arguments to the python docker libraries run() API.
You can create containers that depend on other containers:
from pytest_docker_tools.factories import *
container(
'my_database',
image('my_database_image', path='db'),
volumes={
volume('my_microservice_data'): {'bind': '/var/tmp'},
}
)
container(
'my_microservice',
image('my_microservice_image', path='microservice'),
environment={
'DATABASE_IP': lambda my_database: my_database['ip'],
}
)
Whenever you create a test that uses the my_microservice container it will also start a database container.
