Introduction
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 3.8 through 3.12.
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.














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


Installation
The recommended installation method is using pip:
pip install --upgrade robotframework-seleniumlibrary
Running this command installs also the latest Selenium and Robot Framework
versions, but you still need to install browser drivers separately.
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.


Browser drivers
After installing the library, you still need to install browser and
operating system specific browser drivers for all those browsers you
want to use in tests. These are the exact same drivers you need to use with
Selenium also when not using SeleniumLibrary. More information about
drivers can be found from Selenium documentation.
The general approach to install a browser driver is downloading a right
driver, such as chromedriver for Chrome, and placing it into
a directory that is in PATH. Drivers for different browsers
can be found via Selenium documentation or by using your favorite
search engine with a search term like selenium chrome browser driver.
New browser driver versions are released to support features in
new browsers, fix bug, or otherwise, and you need to keep an eye on them
to know when to update drivers you use.
Alternatively, you can use a tool called WebdriverManager which can
find the latest version or when required, any version of appropriate
webdrivers for you and then download and link/copy it into right
location. Tool can run on all major operating systems and supports
downloading of Chrome, Firefox, Opera & Edge webdrivers.
Here’s an example:
pip install webdrivermanager
webdrivermanager firefox chrome --linkpath /usr/local/bin


Usage
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.

demo project that illustrates using Robot Framework and SeleniumLibrary.

machine. For more information about Robot Framework test data syntax in
general see the Robot Framework User Guide.


Extending SeleniumLibrary
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.
