- Microsoft Edge Driver For Selenium
Hey Tamanna, you can use following lines of code to launch Microsoft Edge driver with Selenium Webdriver: // Set the driver path System.setProperty. I'm trying to get the user agent to change to Microsoft Edge mobile within Edge when I open it with Selenium. I'm currently using Python to write the script. The user agent string looks like this: Mozilla/5.0 (Windows Phone 10.0; Android 4.2.1; Microsoft; Lumia 640 XL LTE) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Mobile.
Selenium is a portable framework for testingweb applications. Selenium provides a playback tool for authoring functional tests without the need to learn a test scripting language (Selenium IDE). It also provides a test domain-specific language (Selenese) to write tests in a number of popular programming languages, including C#, Groovy, Java, Perl, PHP, Python, Ruby and Scala. The tests can then run against most modern web browsers. Selenium runs on Windows, Linux, and macOS. It is open-source software released under the Apache License 2.0.
History[edit]
Selenium was originally developed by Jason Huggins in 2004 as an internal tool at ThoughtWorks. Huggins was later joined by other programmers and testers at ThoughtWorks, before Paul Hammant joined the team and steered the development of the second mode of operation that would later become 'Selenium Remote Control' (RC). The tool was open sourced that year.
In 2005 Dan Fabulich and Nelson Sproul (with help from Pat Lightbody) made an offer to accept a series of patches that would transform Selenium-RC into what it became best known for. In the same meeting, the steering of Selenium as a project would continue as a committee, with Huggins and Hammant being the ThoughtWorks representatives.[3]
In 2007, Huggins joined Google. Together with others like Jennifer Bevan, he continued with the development and stabilization of Selenium RC. At the same time, Simon Stewart at ThoughtWorks developed a superior browser automation tool called WebDriver. In 2009, after a meeting between the developers at the Google Test Automation Conference, it was decided to merge the two projects, and call the new project Selenium WebDriver, or Selenium 2.0.[4]
In 2008, Philippe Hanrigou (then at ThoughtWorks) made 'Selenium Grid', which provides a hub allowing the running of multiple Selenium tests concurrently on any number of local or remote systems, thus minimizing test execution time. Grid offered, as open source, a similar capability to the internal/private Google cloud for Selenium RC. Pat Lightbody had already made a private cloud for 'HostedQA' which he went on to sell to Gomez, Inc.
The name Selenium comes from a joke made by Huggins in an email, mocking a competitor named Mercury, saying that you can cure mercury poisoning by taking selenium supplements. The others that received the email took the name and ran with it.[5]
Components[edit]
Selenium is composed of several components with each taking on a specific role in aiding the development of web application test automation.[6]
Selenium IDE[edit]
Selenium IDE is a complete integrated development environment (IDE) for Selenium tests. It is implemented as a Firefox Add-On and as a Chrome Extension. It allows for recording, editing and debugging of functional tests. It was previously known as Selenium Recorder. Selenium-IDE was originally created by Shinya Kasatani and donated to the Selenium project in 2006. Selenium IDE was previously little-maintained.[7] Selenium IDE began being actively maintained in 2018.[8][9][10][11]

Scripts may be automatically recorded and edited manually providing autocompletion support and the ability to move commands around quickly. Scripts are recorded in Selenese, a special test scripting language for Selenium. Selenese provides commands for performing actions in a browser (click a link, select an option) and for retrieving data from the resulting pages. Englishhindi translator download free.
The 2.x version of the Selenium IDE for Firefox stopped working[12] after the Firefox 55 upgrade and has been replaced by Selenium IDE 3.x.[13]
In addition to the official Selenium IDE project, two alternative Selenium IDE browser extensions are actively maintained:[14] Kantu (Open-SourceGPL license) and Katalon Recorder (Closed Source).
Selenium client API[edit]
As an alternative to writing tests in Selenese, tests can also be written in various programming languages. These tests then communicate with Selenium by calling methods in the Selenium Client API. Selenium currently provides client APIs for Java, C#, Ruby, JavaScript, R and Python.
With Selenium 2, a new Client API was introduced (with WebDriver as its central component). However, the old API (using class Selenium) is still supported.
Selenium Remote Control[edit]
Selenium Remote Control (RC) is a server, written in Java, that accepts commands for the browser via HTTP. RC makes it possible to write automated tests for a web application in any programming language, which allows for better integration of Selenium in existing unit test frameworks. To make writing tests easier, Selenium project currently provides client drivers for PHP, Python, Ruby, .NET, Perl and Java. The Java driver can also be used with JavaScript (via the Rhino engine). An instance of selenium RC server is needed to launch html test case - which means that the port should be different for each parallel run.[citation needed] However, for Java/PHP test case only one Selenium RC instance needs to be running continuously.[15]
Selenium Remote Control was a refactoring of Driven Selenium or Selenium B designed by Paul Hammant, credited with Jason as co-creator of Selenium. The original version directly launched a process for the browser in question, from the test language of Java, .NET, Python or Ruby. The wire protocol (called 'Selenese' in its day) was reimplemented in each language port. After the refactor by Dan Fabulich and Nelson Sproul (with help from Pat Lightbody) there was an intermediate daemon process between the driving test script and the browser. The benefits included the ability to drive remote browsers and the reduced need to port every line of code to an increasingly growing set of languages. Selenium Remote Control completely took over from the Driven Selenium code-line in 2006. The browser pattern for 'Driven'/'B' and 'RC' was response/request, which subsequently became known as Comet.
Selenium RC served as the flagship testing framework of the entire project of selenium for a long-standing time. And significantly Selenium RC is the first and foremost automated web testing tool that enabled users to adopt their preferred programming language. [16][17]
With the release of Selenium 2, Selenium RC has been officially deprecated in favor of Selenium WebDriver. 12th grade.
Selenium WebDriver[edit]
Selenium WebDriver is the successor to Selenium RC. Selenium WebDriver accepts commands (sent in Selenese, or via a Client API) and sends them to a browser. This is implemented through a browser-specific browser driver, which sends commands to a browser and retrieves results. Most browser drivers actually launch and access a browser application (such as Firefox, Google Chrome, Internet Explorer, Safari, or Microsoft Edge); there is also an HtmlUnit browser driver, which simulates a browser using the headless browser HtmlUnit.
Unlike in Selenium 1, where the Selenium server was necessary to run tests, Selenium WebDriver does not need a special server to execute tests. Instead, the WebDriver directly starts a browser instance and controls it. However, Selenium Grid can be used with WebDriver to execute tests on remote systems (see below). Where possible, WebDriver uses native operating system level functionality rather than browser-based JavaScript commands to drive the browser. This bypasses problems with subtle differences between native and JavaScript commands, including security restrictions.[18]
In practice, this means that the Selenium 2.0 API has significantly fewer calls than does the Selenium 1.0 API. Where Selenium 1.0 attempted to provide a rich interface for many different browser operations, Selenium 2.0 aims to provide a basic set of building blocks from which developers can create their own domain-specific language (DSL). One such DSL already exists: the Watir project in the Ruby language has a rich history of good design. Watir-webdriver implements the Watir API as a wrapper for Selenium WebDriver in Ruby. Watir-webdriver is created entirely automatically, based on the WebDriver specification and the HTML specification.
As of early 2012, Simon Stewart (inventor of WebDriver), who was then with Google, and David Burns of Mozilla were negotiating with the W3C to make WebDriver an Internet standard. In July 2012, the working draft was released and the recommendation followed in June 2018.[19] Selenium WebDriver (Selenium 2.0) is fully implemented and supported in Python, Ruby, Java, and C#.
Selenium Grid[edit]
Selenium Grid is a server that allows tests to use web browser instances running on remote machines. With Selenium Grid, one server acts as the central hub. Tests contact the hub to obtain access to browser instances. The hub has a list of servers that provide access to browser instances (WebDriver nodes), and lets tests use these instances. Selenium Grid allows running tests in parallel on multiple machines and to manage different browser versions and browser configurations centrally (instead of in each individual test).
The ability to run tests on remote browser instances is useful to spread the load of testing across several machines and to run tests in browsers running on different platforms or operating systems. The latter is particularly useful in cases where not all browsers to be used for testing can run on the same platform.[20]

Selenium was so named because Huggins, dissatisfied with testing tools on the market, was seeking a name that would position the product as an alternative to Mercury Interactive QuickTest Professional commercial testing software. The name, Selenium, was selected because selenium mineral supplements serve as a cure for mercury poisoning, Huggins explained.

WebDriver allows developers to create automated tests that simulate user interaction. WebDriver tests and simulations differ from JavaScript unit tests in the following ways.
- Accesses functionality and information not available to JavaScript running in browsers.
- Simulates user events or OS-level events more accurately.
- Manages multiple windows, tabs, and webpages in a single test session.
- Runs multiple sessions of Microsoft Edge on a specific machine.
The following section describes how to get started with WebDriver for Microsoft Edge (Chromium).
Install Microsoft Edge (Chromium)
Ensure you install Microsoft Edge (Chromium). To confirm that you have Microsoft Edge (Chromium) installed, navigate to edge://settings/help
, and verify the version number is version 75 or later.
Download Microsoft Edge Driver
To begin automating tests, use the following steps to ensure that the WebDriver version you install matches your browser version.
Find your version of Microsoft Edge.
Navigate to
edge://settings/help
.
Navigate to Microsoft Edge Driver.
Navigate to Get the latest version.
Choose the build of channel that matches your version number of Microsoft Edge.
The Get the latest version section on the Microsoft Edge Driver webpage
Choose a WebDriver language binding
The last component you must download is a language-specific client driver to translate your code (Python, Java, C#, Ruby, JavaScript) into commands the Microsoft Edge Driver runs in Microsoft Edge (Chromium).
Download the WebDriver language binding of your choice. The Microsoft Edge team recommends Selenium 4.00-alpha07 or later, because it supports Microsoft Edge (Chromium). However, you may control Microsoft Edge (Chromium) in all older versions of Selenium, including the current stable Selenium 3 release.
Important
If you previously automated or tested Microsoft Edge (Chromium) using ChromeDriver
and ChromeOptions
classes, your WebDriver code does not run on Microsoft Edge Version 80 or later. To solve the problem, update your tests to use the EdgeOptions
class and download Microsoft Edge Driver.
Use Selenium 3
If you already use Selenium 3, you may have existing browser tests and want to add coverage for Microsoft Edge (Chromium) without changing your version of Selenium. To use Selenium 3 to write automated tests for both Microsoft Edge (EdgeHTML) and Microsoft Edge (Chromium), install the Selenium Tools for Microsoft Edge package to use the updated driver. The EdgeDriver
and EdgeDriverService
classes included in the tools are fully compatible with the built-in equivalents in Selenium 4.
Use the following steps to add the Selenium Tools for Microsoft Edge and Selenium 3 to your project.
Add the Microsoft.Edge.SeleniumTools and Selenium.WebDriver packages to your .NET project using the NuGet CLI or Visual Studio.
Use pip to install the msedge-selenium-tools and selenium packages.
If your Java project uses Maven, copy and paste the following dependency to your pom.xml
file to add msedge-selenium-tools-java.
The Java package is also available to download directly on the Selenium Tools for Microsoft Edge Releases page.
Use npm to install the edge-selenium-tools and selenium-webdriver packages.
Automate Microsoft Edge (Chromium) with WebDriver
To automate a browser using WebDriver, you must first start a WebDriver session using your preferred WebDriver language binding. A session is a single running instance of a browser controlled using WebDriver commands. Start a WebDriver session to launch a new browser instance. The launched browser instance remains open until you close the WebDriver session.
The following content walks you through using Selenium to start a WebDriver session with Microsoft Edge (Chromium). You may run the examples using either Selenium 3 or 4. To use with Selenium 3, the Selenium Tools for Microsoft Edge package must be installed.
Automate Microsoft Edge (Chromium)
Selenium uses the EdgeDriver
class to manage a Microsoft Edge (Chromium) session. To start a session and automate Microsoft Edge (Chromium), create a new EdgeDriver
object and pass it an EdgeOptions
object with the UseChromium
property set to true
.
The EdgeDriver
class only supports Microsoft Edge (Chromium), and doesn't support Microsoft Edge (EdgeHTML). For basic usage, you may create an EdgeDriver
without providing EdgeOptions
.
Note
If your IT admin has set the DeveloperToolsAvailability policy to 2
, Microsoft Edge Driver is blocked from driving Microsoft Edge (Chromium), because the driver uses the Microsoft Edge DevTools. Ensure the DeveloperToolsAvailability policy is set to 0
or 1
to automate Microsoft Edge (Chromium).
Choose Specific Browser Binaries (Chromium-Only)
You may start a WebDriver session with specific Microsoft Edge (Chromium) binaries. For example, you may run tests using the Microsoft Edge preview channels such as Microsoft Edge Beta.
Customize the Microsoft Edge Driver Service
When you use the EdgeOptions
class to create an EdgeDriver
class instance, it creates and launches the appropriate EdgeDriverService
class for either Microsoft Edge (EdgeHTML) or Microsoft Edge (Chromium).
If you want to create an EdgeDriverService
, use the CreateChromiumService()
method to create one configured for Microsoft Edge (Chromium). The CreateChromiumService()
method is useful when you need to add customizations. For example, the following code starts verbose log output.
Note
You do not need to provide the EdgeOptions
object when you pass EdgeDriverService
to the EdgeDriver
instance. The EdgeDriver
class uses the default options for either Microsoft Edge (EdgeHTML) or Microsoft Edge (Chromium) based on the service you provide.
However, if you want to provide both EdgeDriverService
and EdgeOptions
classes, ensure that both are configured for the same version of Microsoft Edge. For example, you may use a default Microsoft Edge (EdgeHTML) EdgeDriverService
class and Chromium properties in the EdgeOptions
class. The EdgeDriver
class throws an error to prevent using different versions.
Selenium Edge Driver Setup
When you use Python, the Edge
object creates and manages the EdgeService
. To configure the EdgeService
, pass extra arguments to the Edge
object as indicated in the following code.
Use the createDefaultService()
method to create an EdgeDriverService
configured for Microsoft Edge (Chromium). Use Java system properties to customize driver services in Java. For example, the following code uses the 'webdriver.edge.verboseLogging'
property to turn on verbose log output.
Selenium Microsoft Edge Chromium
When you use JavaScript, create and configure a Service
with the ServiceBuilder
class. Optionally, you may pass the Service
object to the Driver
object, which starts (and stops) the service for you.
To configure the Service
, run another method in the ServiceBuilder
class before you use the build()
method. Then pass the service
as a parameter in the Driver.createSession()
method.
Use Chromium-Specific Options
If you set the UseChromium
property to true
, you may use the EdgeOptions
class to access the same Chromium-specific properties and methods that are used when you automate other Chromium browsers.
Note
If the UseChromium
property is set to true
, you are not able to use properties and methods for Microsoft Edge (EdgeHTML).
