1 - Getting started

Selenium supports automation of all the major browsers in the market through the use of WebDriver. WebDriver is an API and protocol that defines a language-neutral interface for controlling the behaviour of web browsers. Each browser is backed by a specific WebDriver implementation, called a driver. The driver is the component responsible for delegating down to the browser, and handles communication to and from Selenium and the browser.

This separation is part of a conscious effort to have browser vendors take responsibility for the implementation for their browsers. Selenium makes use of these third party drivers where possible, but also provides its own drivers maintained by the project for the cases when this is not a reality.

The Selenium framework ties all of these pieces together through a user-facing interface that enables the different browser backends to be used transparently, enabling cross-browser and cross-platform automation.

Selenium setup is quite different from the setup of other commercial tools. Before you can start writing Selenium code, you have to install the language bindings libraries for your language of choice, the browser you want to use, and the driver for that browser.

Follow the links below to get up and going with Selenium WebDriver.

If you wish to start with a low-code/record and playback tool, please check Selenium IDE

Once you get things working, if you want to scale up your tests, check out the Selenium Grid.

1.1 - Install a Selenium library

First you need to install the Selenium bindings for your automation project. The installation process for libraries depends on the language you choose to use. Make sure you check the Selenium downloads page to make sure you are using the latest version.

Requirements by language

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    <dependencies>
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>

    testImplementation 'org.seleniumhq.selenium:selenium-java:4.9.1'
    testImplementation 'org.seleniumhq.selenium:selenium-grid:4.9.1'

pip install selenium

python setup.py install

selenium==4.9.1

Install-Package Selenium.WebDriver

dotnet add package Selenium.WebDriver

      <PackageReference Include="Selenium.WebDriver" Version="4.9.0" />

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />   
  </packageSources>
...

gem install selenium-webdriver

gem 'selenium-webdriver', '= 4.9.1'

npm install selenium-webdriver

        "selenium-webdriver": "^4.9.2"

Next Step

Create your first Selenium script

1.2 - Write your first Selenium script

Once you have Selenium installed, you’re ready to write Selenium code.

Eight Basic Components

Everything Selenium does is send the browser commands to do something or send requests for information. Most of what you’ll do with Selenium is a combination of these basic commands

Click on the link to “View full example on GitHub” to see the code in context.

1. Start the session

For more details on starting a session read our documentation on driver sessions

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebDriver driver = new ChromeDriver();

driver = webdriver.Chrome()

        IWebDriver driver = new ChromeDriver();

driver = Selenium::WebDriver.for :chrome

        driver = ChromeDriver()

2. Take action on browser

In this example we are navigating to a web page.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.get("https://www.selenium.dev/selenium/web/web-form.html");

driver.get("https://www.selenium.dev/selenium/web/web-form.html")

        driver.Navigate().GoToUrl("https://www.selenium.dev/selenium/web/web-form.html");

driver.get('https://www.selenium.dev/selenium/web/web-form.html')

    before(async function () {

        driver.get("https://www.selenium.dev/selenium/web/web-form.html")

3. Request browser information

There are a bunch of types of information about the browser you can request, including window handles, browser size / position, cookies, alerts, etc.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.getTitle();

title = driver.title

        var title = driver.Title;

driver.title

    });

        val title = driver.title

4. Establish Waiting Strategy

Synchronizing the code with the current state of the browser is one of the biggest challenges with Selenium, and doing it well is an advanced topic.

Essentially you want to make sure that the element is on the page before you attempt to locate it and the element is in an interactable state before you attempt to interact with it.

An implicit wait is rarely the best solution, but it’s the easiest to demonstrate here, so we’ll use it as a placeholder.

Read more about Waiting strategies.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.manage().timeouts().implicitlyWait(Duration.ofMillis(500));

driver.implicitly_wait(0.5)

        driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500);

driver.manage.timeouts.implicit_wait = 500

        driver.manage().timeouts().implicitlyWait(Duration.ofMillis(500))

5. Find an element

The majority of commands in most Selenium sessions are element related, and you can’t interact with one without first finding an element

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebElement textBox = driver.findElement(By.name("my-text"));
        WebElement submitButton = driver.findElement(By.cssSelector("button"));

text_box = driver.find_element(by=By.NAME, value="my-text")
submit_button = driver.find_element(by=By.CSS_SELECTOR, value="button")

        var textBox = driver.FindElement(By.Name("my-text"));
        var submitButton = driver.FindElement(By.TagName("button"));

text_box = driver.find_element(name: 'my-text')
submit_button = driver.find_element(tag_name: 'button')

      await driver.get('https://www.selenium.dev/selenium/web/web-form.html');

        var textBox = driver.findElement(By.name("my-text"))
        val submitButton = driver.findElement(By.cssSelector("button"))

6. Take action on element

There are only a handful of actions to take on an element, but you will use them frequently.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        textBox.sendKeys("Selenium");
        submitButton.click();

text_box.send_keys("Selenium")
submit_button.click()

        textBox.SendKeys("Selenium");
        submitButton.Click();

text_box.send_keys('Selenium')
submit_button.click

      assert.equal("Web form", title);

        textBox.sendKeys("Selenium")
        submitButton.click()

7. Request element information

Elements store a lot of information that can be requested.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        message.getText();

text = message.text

        var value = message.Text;

message.text

      let textBox = await driver.findElement(By.name('my-text'));

        val value = message.getText()

8. End the session

This ends the driver process, which by default closes the browser as well. No more commands can be sent to this driver instance. See Quitting Sessions.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.quit();

driver.quit()

        driver.Quit();

driver.quit

        driver.quit()

Running Selenium File

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

mvn exec:java -D"exec.mainClass"="dev.selenium.getting_started.FirstScript" -D"exec.classpathScope"=test

python first_script.py

ruby example_script.rb

node example_script.spec.js

Next Steps

Most Selenium users execute many sessions and need to organize them to minimize duplication and keep the code more maintainable. Read on to learn about how to put this code into context for your use case with Using Selenium.

1.3 - Organizing and Executing Selenium Code

If you want to run more than a handful of one-off scripts, you need to be able to organize and work with your code. This page should give you ideas for how to actually do productive things with your Selenium code.

Common Uses

Most people use Selenium to execute automated tests for web applications, but Selenium supports any use case of browser automation.

Repetitive Tasks

Perhaps you need to log into a website and download something, or submit a form. You can create a Selenium script to run with a service at preset times.

Web Scraping

Are you looking to collect data from a site that doesn’t have an API? Selenium will let you do this, but please make sure you are familiar with the website’s terms of service as some websites do not permit it and others will even block Selenium.

Testing

Running Selenium for testing requires making assertions on actions taken by Selenium. So a good assertion library is required. Additional features to provide structure for tests require use of Test Runner.

IDEs

Regardless of how you use Selenium code, you won’t be very effective writing or executing it without a good Integrated Developer Environment. Here are some common options…

• Eclipse
• IntelliJ IDEA
• PyCharm
• RubyMine
• Rider
• WebStorm
• VS Code

Test Runner

Even if you aren’t using Selenium for testing, if you have advanced use cases, it might make sense to use a test runner to better organize your code. Being able to use before/after hooks and run things in groups or in parallel can be very useful.

Choosing

There are many different test runners available.

All the code examples in this documentation can be found in (or is being moved to) our example directories that use test runners and get executed every release to ensure all the code is correct and updated. Here is a list of test runners with links. The first item is the one that is used by this repository and the one that will be used for all examples on this page.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Installing

This is very similar to what was required in Install a Selenium Library. This code is only showing examples for what is being used in our Documentation Examples project.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Asserting

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebElement message = driver.findElement(By.id("message"));

    driver.get("https://www.selenium.dev/selenium/web/web-form.html")

            var title = driver.Title;
            Assert.AreEqual("Web form", title);

    driver.manage.timeouts.implicit_wait = 500

      let title = await driver.getTitle();
      assert.equal("Web form", title);

Setting Up and Tearing Down

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        String title = driver.getTitle();
        assertEquals("Web form", title);

    driver.quit()

    driver = Selenium::WebDriver.for :chrome

    driver.get('https://www.selenium.dev/selenium/web/web-form.html')

  config.after { @driver&.quit }

    before(async function () {
      driver = await new Builder().forBrowser('chrome').build();
    });

    after(async () => await driver.quit());

Executing

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

mvn clean test

gradle clean test

python first_script.py

bundle exec rspec

mocha runningTests.spec.js

npx mocha runningTests.spec.js

        textBox.sendKeys("Selenium");
        submitButton.click();

        WebElement message = driver.findElement(By.id("message"));
        String value = message.getText();

Next Steps

Take what you’ve learned and build out your Selenium code!

As you find more functionality that you need, read up on the rest of our WebDriver documentation.

2 - Driver Sessions

Starting and stopping a session is for opening and closing a browser.

Creating Sessions

Creating a new session corresponds with the W3C command for New session

The session is created automatically by initializing a new Driver class object.

Each language allows a session to be created with arguments from one of these classes (or equivalent):

• Options to describe the kind of session you want; default values are used for local, but this is required for remote
• Some form of HTTP Client configuration (the implementation varies between languages)
• Listeners

Local Driver

The primary unique argument for starting a local driver includes information about starting the required driver service on the local machine.

• Service object applies only to local drivers and provides information about the browser driver

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    WebDriver driver = new ChromeDriver(chromeOptions);

    driver = webdriver.Chrome(options=options)

            driver = new ChromeDriver(options);

      driver.get('https://www.google.com')

    let driver = new Builder()
        .forBrowser(Browser.CHROME)
        .setChromeOptions(options)
        .setChromeService(service)
        .build();

Remote Driver

The primary unique argument for starting a remote driver includes information about where to execute the code. Read the details in the Remote Driver Section

Quitting Sessions

Quitting a session corresponds to W3C command for Deleting a Session.

Important note: the quit method is different from the close method, and it is recommended to always use quit to end the session

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.quit();

        driver.Quit();

  end

        driver.quit()

2.1 - Browser Options

In Selenium 3, capabilities were defined in a session by using Desired Capabilities classes. As of Selenium 4, you must use the browser options classes. For remote driver sessions, a browser options instance is required as it determines which browser will be used.

These options are described in the w3c specification for Capabilities.

Each browser has custom options that may be defined in addition to the ones defined in the specification.

browserName

Browser name is set by default when using an Options class instance.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

	ChromeOptions chromeOptions = new ChromeOptions();
	String name = chromeOptions.getBrowserName();

    options.set_window_rect = True # Full support in Firefox
    driver = webdriver.Firefox(options=options)

      options.page_load_strategy = :normal

browserVersion

This capability is optional, this is used to set the available browser version at remote end. In recent versions of Selenium, if the version is not found on the system, it will be automatically downloaded by Selenium Manager

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

	ChromeOptions chromeOptions = new ChromeOptions();
	String version = "latest";
	chromeOptions.setBrowserVersion(version);

    options = webdriver.ChromeOptions()
    options.strict_file_interactability = True
    driver = webdriver.Chrome(options=options)

pageLoadStrategy

Three types of page load strategies are available.

The page load strategy queries the document.readyState as described in the table below:

The document.readyState property of a document describes the loading state of the current document.

When navigating to a new page via URL, by default, WebDriver will hold off on completing a navigation method (e.g., driver.navigate().get()) until the document ready state is complete. This does not necessarily mean that the page has finished loading, especially for sites like Single Page Applications that use JavaScript to dynamically load content after the Ready State returns complete. Note also that this behavior does not apply to navigation that is a result of clicking an element or submitting a form.

If a page takes a long time to load as a result of downloading assets (e.g., images, css, js) that aren’t important to the automation, you can change from the default parameter of normal to eager or none to speed up the session. This value applies to the entire session, so make sure that your waiting strategy is sufficient to minimize flakiness.

normal (default)

WebDriver waits until the load event fire is returned.

platformName

This identifies the operating system at the remote-end, fetching the platformName returns the OS name.

In cloud-based providers, setting platformName sets the OS at the remote-end.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

acceptInsecureCerts

This capability checks whether an expired (or) invalid TLS Certificate is used while navigating during a session.

If the capability is set to false, an insecure certificate error will be returned as navigation encounters any domain certificate problems. If set to true, invalid certificate will be trusted by the browser.

All self-signed certificates will be trusted by this capability by default. Once set, acceptInsecureCerts capability will have an effect for the entire session.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

}, { browsers: [Browser.CHROME, Browser.FIREFOX]});

timeouts

A WebDriver session is imposed with a certain session timeout interval, during which the user can control the behaviour of executing scripts or retrieving information from the browser.

Each session timeout is configured with combination of different timeouts as described below:

Script Timeout

Specifies when to interrupt an executing script in a current browsing context. The default timeout 30,000 is imposed when a new session is created by WebDriver.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    driver.get("http://www.google.com")
    driver.quit()

Page Load Timeout

Specifies the time interval in which web page needs to be loaded in a current browsing context. The default timeout 300,000 is imposed when a new session is created by WebDriver. If page load limits a given/default time frame, the script will be stopped by TimeoutException.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Implicit Wait Timeout

This specifies the time to wait for the implicit element location strategy when locating elements. The default timeout 0 is imposed when a new session is created by WebDriver.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

unhandledPromptBehavior

Specifies the state of current session’s user prompt handler. Defaults to dismiss and notify state

User Prompt Handler

This defines what action must take when a user prompt encounters at the remote-end. This is defined by unhandledPromptBehavior capability and has the following states:

• dismiss
• accept
• dismiss and notify
• accept and notify
• ignore

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

setWindowRect

Indicates whether the remote end supports all of the resizing and repositioning commands.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

strictFileInteractability

This new capability indicates if strict interactability checks should be applied to input type=file elements. As strict interactability checks are off by default, there is a change in behaviour when using Element Send Keys with hidden file upload controls.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

proxy

A proxy server acts as an intermediary for requests between a client and a server. In simple terms, the traffic flows through the proxy server on its way to the address you requested and back.

A proxy server for automation scripts with Selenium could be helpful for:

• Capture network traffic
• Mock backend calls made by the website
• Access the required website under complex network topologies or strict corporate restrictions/policies.

If you are in a corporate environment, and a browser fails to connect to a URL, this is most likely because the environment needs a proxy to be accessed.

Selenium WebDriver provides a way to proxy settings:

2.3 - Driver Service Class

The Service classes are for managing the starting and stopping of local drivers. They cannot be used with a Remote WebDriver session.

Service classes allow you to specify information about the driver, like location and which port to use. They also let you specify what arguments get passed to the command line. Most of the useful arguments are related to logging.

Default Service instance

To start a driver with a default service instance:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

import org.openqa.selenium.remote.service.DriverService;

from selenium.webdriver.chrome.service import Service as ChromeService

        [TestMethod]
        public void BasicService()

  end

Driver location

Note: If you are using Selenium 4.6 or greater, you shouldn’t need to set a driver location. If you cannot update Selenium or have an advanced use case, here is how to specify the driver location:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

  @Test

    driver_path = os.getenv('CHROMEWEBDRIVER') + 'chromedriver'

        {

Driver port

If you want the driver to run on a specific port, you may specify it as follows:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

  public void setDriverLocation() {

def test_driver_port():

        {

Logging

Logging functionality varies between browsers. Most browsers allow you to specify location and level of logs. Take a look at the respective browser page:

• Chrome
• Edge
• Firefox
• Internet Explorer
• Safari

2.4 - Remote WebDriver

Selenium lets you automate browsers on remote computers if there is a Selenium Grid running on them. The computer that executes the code is referred to as the client computer, and the computer with the browser and driver is referred to as the remote computer or sometimes as an end-node. To direct Selenium tests to the remote computer, you need to use a Remote WebDriver class and pass the URL including the port of the grid on that machine. Please see the grid documentation for all the various ways the grid can be configured.

Basic Example

The driver needs to know where to send commands to and which browser to start on the Remote computer. So an address and an options instance are both required.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    driver = new RemoteWebDriver(gridUrl, options);
  }

    assert "localhost" in driver.command_executor._url
    driver.quit()

            driver = new RemoteWebDriver(GridUrl, options);

    options = Selenium::WebDriver::Options.chrome
    driver = Selenium::WebDriver.for :remote, url: grid_url, options: options

Uploads

Uploading a file is more complicated for Remote WebDriver sessions because the file you want to upload is likely on the computer executing the code, but the driver on the remote computer is looking for the provided path on its local file system. The solution is to use a Local File Detector. When one is set, Selenium will bundle the file, and send it to the remote machine, so the driver can see the reference to it. Some bindings include a basic local file detector by default, and all of them allow for a custom file detector.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    WebElement fileInput = driver.findElement(By.cssSelector("input[type=file]"));
    fileInput.sendKeys(uploadFile.getAbsolutePath());
    driver.findElement(By.id("file-submit")).click();

    file_name_element = driver.find_element(By.ID, "uploaded-files")
    file_name = file_name_element.text

            IWebElement fileInput = driver.FindElement(By.CssSelector("input[type=file]"));
            fileInput.SendKeys(uploadFile);
            driver.FindElement(By.Id("file-submit")).Click();

    driver.file_detector = ->((filename, *)) { filename.include?('selenium') && filename }
    file_input = driver.find_element(css: 'input[type=file]')
    file_input.send_keys(upload_file)
    driver.find_element(id: 'file-submit').click

Downloads

Chrome, Edge and Firefox each allow you to set the location of the download directory. When you do this on a remote computer, though, the location is on the remote computer’s local file system. Selenium allows you to enable downloads to get these files onto the client computer.

Enable Downloads in the Grid

Regardless of the client, when starting the grid in node or standalone mode, you must add the flag:

--enable-managed-downloads true

Enable Downloads in the Client

The grid uses the se:downloadsEnabled capability to toggle whether to be responsible for managing the browser location. Each of the bindings have a method in the options class to set this.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    options.setEnableDownloads(true);
    driver = new RemoteWebDriver(gridUrl, options);

    driver.get('https://www.selenium.dev/selenium/web/downloads/download.html')
    driver.find_element(By.ID, "file-1").click()
    driver.find_element(By.ID, "file-2").click()

            {
                EnableDownloads = true
            };
            driver = new RemoteWebDriver(GridUrl, options);

            driver.Url = "https://selenium.dev/selenium/web/downloads/download.html";
