SeleniumLibrary is a web testing library for Robot Framework that utilizes the Selenium tool internally. The project is hosted on GitHub and downloads can be found from PyPI.

SeleniumLibrary currently works with Selenium 4. It supports Python 3.10 through 3.13. In addition to the normal Python interpreter, it works also with PyPy.

SeleniumLibrary is based on the "old SeleniumLibrary" that was forked to Selenium2Library and then later renamed back to SeleniumLibrary. See the VERSIONS.rst for more information about different versions and the overall project history.

See keyword documentation for available keywords and more information about the library in general.

The recommended installation method is using pip:

pip install --upgrade robotframework-seleniumlibrary

Running this command installs also the latest Selenium and Robot Framework versions. The --upgrade option can be omitted when installing the library for the first time.

It is possible to install directly from the GitHub repository. To install latest source from the master branch, use this command:

pip install git+https://github.com/robotframework/SeleniumLibrary.git

Please note that installation will take some time, because pip will clone the SeleniumLibrary project to a temporary directory and then perform the installation.

See Robot Framework installation instructions for detailed information about installing Python and Robot Framework itself. For more details about using pip see its own documentation.

Browsers and drivers are installed and managed automatically by Selenium Manager. For more information, see the Selenium documentation.

To use SeleniumLibrary in Robot Framework tests, the library needs to first be imported using the Library setting as any other library. The library accepts some import time arguments, which are documented in the keyword documentation along with all the keywords provided by the library.

When using Robot Framework, it is generally recommended to write as easy-to-understand tests as possible. The keywords provided by SeleniumLibrary is pretty low level, though, and often require implementation-specific arguments like element locators to be passed as arguments. It is thus typically a good idea to write tests using Robot Framework's higher-level keywords that utilize SeleniumLibrary keywords internally. This is illustrated by the following example where SeleniumLibrary keywords like Input Text are primarily used by higher-level keywords like Input Username.

The above example is a slightly modified version of an example in a demo project that illustrates using Robot Framework and SeleniumLibrary. See the demo for more examples that you can also execute on your own machine. For more information about Robot Framework test data syntax in general see the Robot Framework User Guide.

Before creating your own library which extends the SeleniumLibrary, please consider would the extension be also useful also for general usage. If it could be useful also for general usage, please create a new issue describing the enhancement request and even better if the issue is backed up by a pull request.

If the enhancement is not generally useful, example solution is domain specific, then the SeleniumLibrary offers public APIs which can be used to build its own plugins and libraries. Plugin API allows us to add new keywords, modify existing keywords and modify the internal functionality of the library. Also new libraries can be built on top of the SeleniumLibrary. Please see extending documentation for more details about the available methods and for examples how the library can be extended.

If the provided documentation is not enough, there are various community channels available:

• #seleniumlibrary and #seleniumlibrary-dev channels in Robot Framework Slack community
• Robot Framework forum has channel for SeleniumLibrary.
• SeleniumLibrary issue tracker for bug reports and concrete enhancement requests
• Other community channels including paid support
