Selenium is an umbrella project encapsulating a variety of tools andlibraries enabling web browser automation. Selenium specificallyprovides infrastructure for the W3C WebDriver specification— a platform and language-neutral coding interface compatible with allmajor web browsers.

The project is made possible by volunteer contributors who'vegenerously donated thousands of hours in code development and upkeep.

Selenium's source code is made available under the Apache 2.0 license.

Documentation

We have an Ubuntu server which we use for running Selenium tests with Chrome and. Def start_selenium_webdriver(self, chrome. To download the chrome web driver.

Narrative documentation:

• New Handbook (work in progress)

Install Chrome Driver (Win32, macOS, and Linux64) for Selenium WebDriver into your Unit Test Project. 'chromedriver(.exe)' is copied to bin folder from package folder when the build process. ChromeDriver - WebDriver for Chrome. Fixes a bug where Chromedriver fails to retrieve default prompt text in Chrome 62+. The latest Selenium.

Building

In order to build Selenium, you'll generally use the ./go command. ./go is a Rake script,which wraps the main build too, bazel.

Bazel

Bazel was built by the fine folks at Google. Bazel manages dependencydownloads, generates the Selenium binaries, executes tests and does it all rather quickly.

More detailed instructions for getting Bazel running are below, but if you can successfully getthe java and javascript folders to build without errors, you should be confident that you have thecorrect binaries on your system.

Before Building

Ensure that you have Chrome installed and thechromedriver that matchesyour Chrome version available on your $PATH. You may have to update this from time to time.

Common Build Targets

To build the most commonly-used modules of Selenium from source, execute this command from the rootproject folder:

If you have some extra time on your hands, you can run this command to get extra confidencethat your build is successful. This will do a lot more work to build all the javascript artifacts:

If you're making changes to the java/ or javascript/ folders in this project, and this commandexecutes without errors, you should be able to create a PR of your changes. (See also CONTRIBUTING.md)

Build Details

• Bazel files are called BUILD.bazel
• crazyfun build files are calledbuild.desc. This is an older build system, still in use in the project
• There is also a main Rakefile

The order the modules are built is determined by the build system. If you want to build anindividual module (assuming all dependent modules have previously been built), try the following:

In this case, javascript/atoms is the module directory,test is a target in that directory's build.desc file,and run is the action to run on that target.

As you see build targets scroll past in the log,you may want to run them individually. crazyfun can run them individually,by target name, as long as :run is appended (see above).

To list all available targets, you can append the -T flag:

Requirements

• The latest version of the Java 11 OpenJDK
• java and jar on the PATH (make sure you use java executable from JDK but not JRE).
  • To test this, try running the command javac. This command won't exist if you only have the JREinstalled. If you're met with a list of command-line options, you're referencing the JDK properly.
• python on the PATH
• The Requests Library for Python: pip install requests
• MacOS users should have the latest version of XCode installed, including the command-line tools.The following command should work:

Although the build system is based on rake, it's strongly advisedto rely on the version of JRuby in third_party/ that is invoked bygo. The only developer type who would want to deviate from this isthe “build maintainer” who's experimenting with a JRuby upgrade.

Optional Requirements

• Python 3.4+ (if you want to run Python tests for this version)
• Ruby 2.0

Internet Explorer Driver

If you plan to compile theIE driver,you also need:

• 32 and 64 bit cross compilers

The build will work on any platform, but the tests for IE will beskipped silently if you are not building on Windows.

Common Tasks (Bazel)

To build the bulk of the Selenium binaries from source, run thefollowing command from the root folder:

To build the grid deployment jar, run this command:

To run tests within a particular area of the project, use the 'test' command, followedby the folder or target. Tests are tagged with 'small', 'medium', or 'large', and can be filteredwith the --test_size_filters option:

Bazel's 'test' command will run all tests in the package, including integration tests. Expectthe test java/... to launch browsers and consume a considerable amount of time and resources.

Tour

The code base is generally segmented around the languages used towrite the component. Selenium makes extensive use of JavaScript, solet's start there. Working on the JavaScript is easy. First of all,start the development server:

Now, navigate tohttp://localhost:2310/javascript.You'll find the contents of the javascript/ directory being shown.We use the ClosureLibrary fordeveloping much of the JavaScript, so now navigate tohttp://localhost:2310/javascript/atoms/test.

The tests in this directory are normal HTML files with names endingwith _test.html. Click on one to load the page and run the test. Youcan run all the JavaScript tests using:

Maven POM files

Here is the public Selenium Mavenrepository.

Build Output

Selenium Chrome Driver Download Win 64 Bit

./go only makes a top-level build directory. Outputs are placedunder that relative to the target name. Which is probably bestdescribed with an example. For the target:

The output is found under:

If you watch the build, each step should print where its output isgoing. Java test outputs appear in one of two places: either underbuild/test_logs for JUnit or inbuild/build_log.xml for TestNGtests. If you'd like the build to be chattier, just append log=trueto the build command line.

More general, but basic, help for go…

go is just a wrapper aroundRake, so you can use the standardcommands such as rake -T to get more information about availabletargets.

Maven per se

If it is not clear already, Selenium is not built with Maven. It isbuilt with bazel, though that is invoked with go as outlined above,so you do not really have to learn too much about that.

That said, it is possible to relatively quickly build Selenium piecesfor Maven to use. You are only really going to want to do this whenyou are testing the cutting-edge of Selenium development (which wewelcome) against your application. Here is the quickest way to buildand deploy into your local maven repository (~/.m2/repository), whileskipping Selenium's own tests.

Download Selenium Server

The maven jars should now be in your local ~/.m2/repository.

Bazel Installation/Troubleshooting

MacOS

bazelisk

Bazelisk is a Mac-friendly launcher for Bazel. To install, follow these steps:

XCode

Python Selenium Chrome Driver

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: usethe Bazelisk project (courtesy of philwo), a pure golang implementation of Bazel. In order toinstall Bazelisk, first verify that your XCode will cooperate: execute the following command:

xcode-select -p

If the value is /Applications/Xcode.app/Contents/Developer/, you can proceed with bazeliskinstallation. If, however, the return value is /Library/Developer/CommandLineTools/, you'llneed to redirect the XCode system to the correct value.

How To Install Chrome Driver For Selenium

The first command will prompt you for a password. The second step requires you to read a new XCodelicense, and then accept it by typing 'agree'.
