Plugins for Web Development

Web-based projects have their own testing hoops to jump through. Even pytest doesn’t make testing web applications trivial. However, quite a few pytest plugins help make it easier.

pytest-selenium: Test with a Web Browser

Selenium is a project that is used to automate control of a web browser. The pytest-selenium plugin^[51] is the Python binding for it. With it, you can launch a web browser and use it to open URLs, exercise web applications, and fill out forms. You can also programmatically control the browser to test a web site or web application.

pytest-django: Test Django Applications

Django is a popular Python-based web development framework. It comes with testing hooks that allow you to test different parts of a Django application without having to use browser-based testing. By default, the builtin testing support in Django is based on unittest. The pytest-django plugin^[52] allows you to use pytest instead of unittest to gain all the benefits of pytest. The plugin also includes helper functions and fixtures to speed up test implementation.

pytest-flask: Test Flask Applications

Flask is another popular framework that is sometimes referred to as a microframework. The pytest-flask plugin^[53] provides a handful of fixtures to assist in testing Flask applications.
