Pyramid server fixture for py.test

Project description

Pyramid server fixture for py.test. The server is session-scoped by default and run in a subprocess and temp dir, and as such is a ‘real’ server that you can point a Selenium webdriver at.

Installation

Install using your favourite package manager:

pip install pytest-pyramid
#  or..
easy_install pytest-pyramid

Enable the fixture explicitly in your tests or conftest.py (not required when using setuptools entry points):

pytest_plugins = ['pytest_pyramid_server']

Configuration

This fixture searches for its configuration in the current working directory called ‘testing.ini’. All .ini files in the cwd will be copied to the tempdir so that paster-style config chaining still works. For example:

my-pyramid-app/
              src/             # Project code is in here
              setup.py         # Project setup.py
              development.ini  # Development settings
              production.ini   # Production settings
              testing.ini      # Testing settings, will be used if tests
                               # are invoked using 'py.test' from this
                               # directory

Example

Here’s a noddy test case showing the main functionality:

def test_pyramid_server(pyramid_server):
    # This is the http://{host}:{port} of the running server. It will attempt to resolve
    # to externally accessable IPs so a web browser can access it.
    assert pyramid_server.uri.startswith('http')

    # GET a document from the server.
    assert pyramid_server.get('/orders/macbooks', as_json=True)  == {'id-1234': 'MPB-15inch'}

    # POST a document to the server.
    assert pyramid_server.post('/login', 'guest:password123').response_code == 200

    # ``path.py`` path object to the running config file
    assert pyramid_server.working_config.endswith('testing.ini')

PyramidServer class

Using this with the default pyramid_server py.test fixture is good enough for a lot of use-cases however you may wish to have more fine-grained control about the server configuration. To do this you can use the underlying server class directly - this is an implenentation of the pytest-server-fixture framework and as such acts as a context manager:

from pytest_pyramid import PyramidTestServer

def test_custom_server():
    with PyramidTestServer(
           # You can specify you own config directory and name
           config_dir='/my/config',
           config_fileme='my_testing.ini',

          # You can set arbitrary config variables in the constructor
          extra_config_vars={'my_config_section': {'my_dbname: 'foo',
                                                   'my_dbpass: 'bar'}}
       ) as server:
           assert not server.dead
           assert 'my_dbname = foo' in server.working_config.text()

    # Server should now be dead
    assert server.dead

pytest-webdriver and PageObjects integration

The pytest-webdriver plugin will detect when this plugin is active and set its default base URL to the url of the running server. This is a nice way of avoiding lots of string manipulation in your browser tests when using Page Objects:

from page_objects import PageObject, PageElement

class LoginPage(PageObject):
    username = PageElement(id_='username')
    password = PageElement(name='password')
    login = PageElement(css='input[type="submit"]')

def test_login_page(webdriver, pyramid_server):
    page = LoginPage(webdriver)
    page.login.click()
    page.get('/foo/bar')
    assert webdriver.getCurrentUrl() == pyramid_server.uri + '/foo/bar'
