Project description

A pytest plugin to run Xvfb for tests.


Installation

You can install “pytest-xvfb” via pip from PyPI:

$ pip install pytest-xvfb

Usage

With Xvfb and the plugin installed, your testsuite automatically runs with Xvfb. This allows tests to be run without windows popping up during GUI tests or on systems without a display (like a CI).

If Xvfb is not installed, the plugin does not run and your tests will still work as normal. However, a warning message will print to standard output letting you know that Xvfb is not installed.

If you’re currently using xvfb-run in something like .travis.yml, simply remove it and install this plugin instead - then you’ll also have the benefits of Xvfb locally.

Features

You can pass --no-xvfb to explicitly turn off Xvfb (e.g. to visually inspect a failure).

You can mark tests with @pytest.mark.no_xvfb to skip them when they’re running with Xvfb.

A xvfb fixture is available with the following attributes:

  • width: The configured width of the screen.
  • height: The configured height of the screen.
  • colordepth: The configured colordepth of the screen.
  • args: The arguments to be passed to Xvfb.
  • display: The display number (as int) which is used.

Contributing

Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.

License

Distributed under the terms of the MIT license, “pytest-xvfb” is free and open source software
