pytest-selenium

What it is and what it does

pytest-selenium bridges pytest and Selenium WebDriver, allowing you to write browser-based UI tests using pytest's fixture and parametrization system. It depends on pytest, selenium, requests, tenacity, and several pytest plugins (pytest-html, pytest-variables, pytest-base-url) to provide a cohesive testing environment. The plugin handles the plumbing of WebDriver lifecycle and test reporting, so you focus on test logic rather than browser setup.

The package is designed for teams running web automation tests at scale—it supports Python 3.8 through 3.12 and works on macOS, Windows, and POSIX systems. With active maintenance since 2015 and a recent commit on 2026-05-25, it is a mature choice in the pytest ecosystem for UI testing, though you will still need to manage WebDriver binaries and browser compatibility separately.

Use it for:

• Write cross-browser UI tests for web applications using pytest's familiar syntax and fixtures.
• Integrate browser-based tests into CI/CD pipelines with pytest's reporting and plugin ecosystem.
• Automate regression testing of web interfaces across multiple browsers and operating systems.
• Combine Selenium tests with unit tests in a single pytest suite for end-to-end validation.
• Leverage pytest parametrization to run the same UI test against different browsers or data sets.

AI-flagged interpretation of the facts on this page — verify before relying

pytest-selenium is a pytest plugin that integrates Selenium WebDriver into pytest test suites, enabling browser automation and web UI testing within the pytest framework.

Yes, if you are building browser automation tests and want to use pytest. The plugin is stable, actively maintained, has low install friction, and integrates cleanly with pytest's ecosystem. The MPL 2.0 copyleft license is a consideration for proprietary codebases. No known vulnerabilities.

Installing pytest-selenium

Before you install

Low install friction with a pure-wheel distribution. The package is actively maintained (last commit 2026-05-25) and marked Production/Stable, with support across Python 3.8, 3.9, 3.10, 3.11, and 3.12 on CPython and PyPy.

License in practice

Licensed under Mozilla Public License 2.0 (MPL 2.0), a copyleft license. This requires derivative works to be distributed under the same license and disclose source code changes, which may constrain proprietary use.

Quickstart

pip install pytest-selenium

import pytest
from selenium import webdriver

# Use pytest fixtures provided by the plugin
def test_example(selenium):
    selenium.get('http://example.com')
    assert 'Example' in selenium.title

Requires Selenium WebDriver and a compatible browser driver (e.g., chromedriver, geckodriver) installed and in PATH or configured via environment.

Verify before relying

• Whether the plugin provides built-in fixtures for common browser setup/teardown patterns beyond what Selenium itself offers.
• Support for parallel test execution and how it interacts with browser driver management.
• Integration capabilities with cloud providers like BrowserStack or Sauce Labs (mentioned in keywords but not detailed in excerpt).
