The Selenium project welcomes contributions from everyone. There are a number of ways you can help:
When opening new issues or commenting on existing issues please make sure discussions are related to concrete technical issues with the Selenium software.
It‘s imperative that issue reports outline the steps to reproduce the defect. If the issue can’t be reproduced it will be closed. Please provide concise reproducible test cases and describe what results you are seeing and what results you expect.
Issues shouldn't be used for support. Please address questions to the selenium-users@ mailing list. Discussion of high level project ideas or non-technical topics should move to the selenium-developers@ mailing list instead.
We also need help with triaging issues that needs investigation. This means asking the right questions, procuring the right information to properly debug and verify the issue, and bisecting a commit range if the issue is a regression.
If you find that Selenium is missing something, feel free to open an issue with details describing what feature(s) you'd like added or changed.
If you'd like a hand at trying to implement the feature yourself, please refer to the Code Contributions section of the document.
Selenium is a big software project and documentation is key to understanding how things work and learning effective ways to exploit its potential.
The seleniumhq.github.io repository contains both Selenium’s site and documentation. This is an ongoing effort (not targeted at any specific release) to provide updated information on how to use Selenium effectively, how to get involved and how to contribute to Selenium.
The official documentation of Selenium is at https://selenium.dev/documentation/. More details on how to get involved and contribute, please check the site's and documentation contributing guidelines.
The Selenium project welcomes new contributors. Individuals making significant and valuable contributions over time are made Committers and given commit-access to the project.
If you're looking for easy bugs, have a look at issues labelled E-easy on Github.
This document will guide you through the contribution process.
Fork the project on Github and check out your copy locally.
% git clone git@github.com:username/selenium.git % cd selenium % git remote add upstream git://github.com/seleniumhq/selenium.git
We bundle dependencies in the third-party/ directory that is not part of the proper project. Any changes to files in this directory or its subdirectories should be sent upstream to the respective projects. Please don't send your patch to us as we cannot accept it.
We do accept help in upgrading our existing dependencies or removing superfluous dependencies. If you need to add a new dependency it‘s often a good idea to reach out to the committers on the IRC channel or the mailing list to check that your approach aligns with the project’s ideas. Nothing is more frustrating than seeing your hard work go to waste because your vision doesn‘t align with the project’s.

Create a feature branch and start hacking:
% git checkout -b my-feature-branch
We practice HEAD-based development, which means all changes are applied directly on top of master.
First make sure git knows your name and email address:
% git config --global user.name 'Santa Claus' % git config --global user.email 'santa@example.com'
Writing good commit messages is important. A commit message should describe what changed, why, and reference issues fixed (if any). Follow these guidelines when writing one:
Fixes #N, where N is the issue number the commit fixes, if any.A good commit message can look like this:
explain commit normatively in one line Body of commit message is a few lines of text, explaining things in more detail, possibly giving some background about the issue being fixed, etc. The body of the commit message can be several paragraphs, and please do proper word-wrap and keep columns shorter than about 72 characters or so. That way `git log` will show things nicely even when it is indented. Fixes #141
The first line must be meaningful as it's what people see when they run git shortlog or git log --oneline.
Use git rebase (not git merge) to sync your work from time to time.
% git fetch upstream % git rebase upstream/master
Bug fixes and features should have tests. Look at other tests to see how they should be structured.
% git push origin my-feature-branch
Go to https://github.com/yourusername/selenium.git and press the Pull Request and fill out the form.
Pull requests are usually reviewed within a few days. If there are comments to address, apply your changes in new commits (preferably fixups) and push to the same branch.
When code review is complete, a committer will take your PR and integrate it on Selenium's master branch. Because we like to keep a linear history on the master branch, we will normally squash and rebase your branch history.
From your create your issue or pull request, through code review and towards integration, it will be assigned different Github labels. The labels serve for the committers to more easily keep track of work that's pending or awaiting action.
Component labels are yellow and carry the C prefix. They highlight the subsystem or component your PR makes changes in.
The driver labels (D) indicate if the changes are related to a WebDriver implementation or the Selenium atoms.
The review labels (R) are:
Issues are labelled to make them easier to categorise and find by:
