pytest-nginx

pytest-nginx is a pytest plugin, that allows you to test code, which requires communicating with a full-fledged web server. Custom fixtures can be made which manage the content of the server root directory.

Usage

The plugin contains one fixture:

• nginx_proc - session scoped fixture, which manages the nginx daemon with the most basic configuration for serving static files.
• nginx_php_proc - session scoped fixture, which manages the nginx daemon and the php-fpm daemon, both configured to work together.

All fixtures take the name of a fixture managing the server root directory. In the simplest case it is an empty temporary directory managed with the tmpdir_factory built-in fixture:

from pytest_nginx import factories

@pytest.fixture(scope="session")
def nginx_server_root(tmpdir_factory):
    return tmpdir_factory.mktemp("nginx-server-root")

nginx_proc = factories.nginx_proc("nginx_server_root")

To manage the served content, you can create additional module or function-scoped fixtures on top of nginx_proc:

@pytest.fixture(scope="module")
def nginx_hello_world(nginx_proc):
    f = open(os.path.join(nginx_proc.server_root, "index.html"), "w")
    f.write("Hello world! This is pytest-nginx serving on host {}, port {}."
            .format(nginx_proc.host, nginx_proc.port))
    f.close()
    return nginx_proc

Configuration

You can define your settings in three ways: with fixture factory arguments, with command line options and with pytest.ini configuration options. These settings are handled in the following order:

1. Fixture factory arguments
2. Command line options
3. pytest.ini configuration options

Examples showing how to specify the port number:

• Pass it as an argument to the factory function:

  nginx_proc = factories.nginx_proc(port=8888)

• Use the --nginx-port command line option when running pytest:

  pytest ./tests --nginx-port=8888
  

• Add the nginx_port option to the pytest.ini file:

  [pytest]
  nginx_port = 8888
