Selenium is an umbrella project encapsulating a variety of tools and libraries enabling web browser automation. Selenium specifically provides an infrastructure for the W3C WebDriver specification — a platform and language-neutral coding interface compatible with all major web browsers.
The project is made possible by volunteer contributors who've generously donated thousands of hours in code development and upkeep.
Selenium's source code is made available under the Apache 2.0 license.

To build the most commonly-used modules of Selenium from source, execute this command from the root project folder:
bazel build java/...
If you want to test you can run then you can do so by running the following command
bazel test //java/... --test_size_filters=small,medium,large --test_tag_filters=<browser>
test_size_filters argument takes small, medium, large. Small are akin to unit tests, medium is akin to integration tests, and large is akin to end to end tests.
test_tag_filters allow us to pass in browser names and a few different tags that we can find in the code base.
To build the Grid deployment jar, run this command:
bazel build grid
The log will show where the output jar is located.
To build the NodeJS bindings you will need to run:
To run the tests run:
You can pass in the environment variable
SELENIUM_BROWSER with the name of the browser.
To publish to NPM run:
Click to see Python Build Steps
If you want to build the python bindings run:
bazel build //py:selenium
To run the tests run:
bazel test //py:test-<browsername>
If you add
--//common:pin_browsers it will download the browsers and drivers for you to use.
To install locally run:
bazel build //py:selenium-wheel pip install bazel-bin/py/selenium-*.whl
To publish run:
bazel build //py:selenium-wheel twine upload bazel-bin/py/selenium-*.whl
Click to see Ruby Build Steps
To build the Ruby code run:
bazel build //rb/...
Click to see .NET Build Steps
To build the .NET code run:
bazel build //dotnet/...
bazel build //dotnet/test/common:chrome
Bazel files are called BUILD.bazel, and the order the modules are built is determined by the build system. If you want to build an individual module (assuming all dependent modules have previously been built), try the following:
In this case,
test is a target in that directory's
As you see build targets scroll past in the log, you may want to run them individually.
bazel makes a top-level group of directories with the
bazel- prefix on each directory.
To build the bulk of the Selenium binaries from source, run the following command from the root folder:
To run tests within a particular area of the project, use the "test" command, followed by the folder or target. Tests are tagged with "small", "medium", or "large", and can be filtered with the
bazel test --test_size_filters=small,medium java/...
Bazel's "test" command will run all tests in the package, including integration tests. Expect the
test java/... to launch browsers and consume a considerable amount of time and resources.
To bump the versions of the pinned browsers to their latest stable versions:
bazel run scripts:pinned_browsers > temp.bzl && mv temp.bzl common/repositories.bzl
Most of the team use either Intellij IDEA or VS.Code for their day-to-day editing. If you're working in IntelliJ, then we highly recommend installing the Bazel IJ plugin which is documented on its own site.
If you do use IntelliJ and the Bazel plugin, there is a project view checked into the tree in scripts/ij.bazelproject which will make it easier to get up running, and editing code :)

Selenium is not built with Maven. It is built with
bazel, though that is invoked with
go as outlined above, so you do not have to learn too much about that.
That said, it is possible to relatively quickly build Selenium pieces for Maven to use. You are only really going to want to do this when you are testing the cutting-edge of Selenium development (which we welcome) against your application. Here is the quickest way to build and deploy into your local maven repository (
~/.m2/repository), while skipping Selenium's own tests.
The maven jars should now be in your local
By default, Bazel runs these tests in your current X-server UI. If you prefer, you can alternatively run them in a virtual or nested X-server.
bazel test --test_env=DISPLAY=:99 //java/... --test_tag_filters=chrome
An easy way to run tests in a virtual X-server is to use Bazel's
bazel test --run_under="xvfb-run -a" //java/... --test_tag_filters=chrome
If you're finding it hard to set up a development environment using bazel and you have access to Docker, then you can build a Docker image suitable for building and testing Selenium in from the Dockerfile in the dev image directory.
Bazelisk is a Mac-friendly launcher for Bazel. To install, follow these steps:
brew tap bazelbuild/tap && \ brew uninstall bazel; \ brew install bazelbuild/tap/bazelisk
If you're getting errors that mention Xcode, you'll need to install the command-line tools.
Bazel for Mac requires some additional steps to configure properly. First things first: use the Bazelisk project (courtesy of philwo), a pure golang implementation of Bazel. In order to install Bazelisk, first verify that your Xcode will cooperate: execute the following command:
If the value is
/Applications/Xcode.app/Contents/Developer/, you can proceed with bazelisk installation. If, however, the return value is
/Library/Developer/CommandLineTools/, you'll need to redirect the Xcode system to the correct value.
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer/ sudo xcodebuild -license
The first command will prompt you for a password. The second step requires you to read a new Xcode license, and then accept it by typing "agree".

While you are automating your test cases with Selenium automation, here is how to start implementing Selenium getAttribute() method to get the best results.
Testing a web page can be a gargantuan task, considering all the elements and variables that come together to make a page work. Selenium automation is a great way to overcome these challenges and automate everything you would manually do. For example, Selenium makes it so much easier to take a screenshot using Python instead of doing it manually every time you come across a website issue.
Similarly, there are multiple scenarios while writing automation test cases when we need to verify a specific attribute on the web page. To ease our execution, the method to
getAttribute() in Selenium comes to the rescue. In this blog, we will understand what an attribute is and how we can handle web elements’ attributes using the Selenium
Let’s get to it, shall we?

In today’s fast-paced world of software development, we have new technologies and languages for development coming on very frequently. With this comes several testing and automation tools and frameworks in the related market. Choosing the right set of tools and frameworks becomes an absolute necessity because it impacts the accuracy and TTM (Time to Market).
So let’s get started!!

Selenium has gone through a tremendous evolution since its introduction and that’s the reason today it is the most popular and powerful automation testing tool. The newly released Selenium 4 is creating a lot of buzz and the complete testing community is looking forward to exploring its updated features.
Before we dive into Selenium 4, let’s have a brief introduction to its previous versions. Selenium 1 was declared as the free open source automation testing framework in the year 2004 consisting of selenium IDE, RC, and web driver. Whereas, the Selenium 2 released in 2011 consisted of the IDE, Web driver, and Grid. The RC server was merged with the web driver, as the web driver facilitated easy automation scripting for the browsers. Selenium 3 was officially released in 2016. One of the most noticeable changes in selenium 3 was the replacement of the selenium core with the web driver-backed option, the introduction of the gecko driver, and W3C web driver integration.
With the aim of executing much seamless, accurate and faster test automation, Selenium 4 was released on 24th April 2019. So let’s unleash all the major features of selenium 4 which sets it apart from the earlier versions delivering better test automation. There are a lot of exciting features in Selenium 4 across the complete suite i.e. Selenium IDE, Webdriver and Grid. In Selenium 4 though the Webdriver captures the spotlight, we will cover the updated features of selenium IDE and selenium grid. So first of all let’s define the different user groups for the Selenium suite.
Selenium is a suite of tools that caters to the various requirements of the project such as:
Let us explore the features of Selenium 4 across the different Selenium Tools.

Manual cross-browser testing is neither efficient nor scalable as it will take ages to test on all permutations and combinations of browsers, operating systems, and their versions. Like every developer, I have also gone through that ‘I can do it all phase’. But if you are stuck validating your code changes over hundreds of browsers and OS combinations then your release window is going to look even shorter than it already is. This is why automated browser testing can be pivotal for modern-day release cycles as it speeds up the entire process of cross-browser compatibility .

Localization automation testing is essential for your product to gain good standing globally. Read on to learn how to do localization testing using Selenium WebDriver.
Automation testing is vital to the entire process of delivering a successful web product. The challenge associated with testing a web site or web app grows exponentially if it’s built for a global audience (particularly non-English audience). Automation tests have to be performed to ensure that the product features (including the content) cater to specific locales. That’s why localization testing using Selenium WebDriver has become increasingly relevant when a plethora of software products are being built for the world!
We’re sure you’ve come across scenarios where some content or portion of the website did not render correctly in a specific location. This is a common dilemma that most Selenium test automation engineers often come across, and it is extremely likely that incorrectly formatted strings are a part of the resource files. As a part of localization testing using Selenium WebDriver, we need to verify if the website (or app) looks and functions the same after localization automation testing is applied.
That is precisely what this blog aims to deliver. By the end of this blog, you would be comfortable performing localization testing using Selenium WebDriver as we touch upon the critical aspects of localization, including how to perform localization automation testing.
