WebDriver provides an API for working with the three types of native
popup messages offered by JavaScript. These popups are styled by the
browser and offer limited customisation.
Alerts
The simplest of these is referred to as an alert, which shows a
custom message, and a single button which dismisses the alert, labelled
in most browsers as OK. It can also be dismissed in most browsers by
pressing the close button, but this will always do the same thing as
the OK button. See an example alert.
WebDriver can get the text from the popup and accept or dismiss these
alerts.
Alertalert=driver.switchTo().alert();//Store the alert text in a variable and verify itStringtext=alert.getText();assertEquals(text,"Sample Alert");//Press the OK buttonalert.accept();
element=driver.find_element(By.LINK_TEXT,"See an example alert")element.click()wait=WebDriverWait(driver,timeout=2)alert=wait.until(lambdad:d.switch_to.alert)text=alert.textalert.accept()
//Click the link to activate the alertdriver.FindElement(By.LinkText("See an example alert")).Click();//Wait for the alert to be displayed and store it in a variableIAlertalert=wait.Until(ExpectedConditions.AlertIsPresent());//Store the alert text in a variablestringtext=alert.Text;//Press the OK buttonalert.Accept();
# Store the alert reference in a variablealert=driver.switch_to.alert# Get the text of the alertalert.text# Press on Cancel buttonalert.dismiss
//Click the link to activate the alert
driver.findElement(By.linkText("See an example alert")).click()//Wait for the alert to be displayed and store it in a variable
valalert=wait.until(ExpectedConditions.alertIsPresent())//Store the alert text in a variable
valtext=alert.getText()//Press the OK button
alert.accept()
Confirm
A confirm box is similar to an alert, except the user can also choose
to cancel the message. See
a sample confirm.
This example also shows a different approach to storing an alert:
alert=driver.switchTo().alert();//Store the alert text in a variable and verify ittext=alert.getText();assertEquals(text,"Are you sure?");//Press the Cancel buttonalert.dismiss();
element=driver.find_element(By.LINK_TEXT,"See a sample confirm")driver.execute_script("arguments[0].click();",element)wait=WebDriverWait(driver,timeout=2)alert=wait.until(lambdad:d.switch_to.alert)text=alert.textalert.dismiss()
//Click the link to activate the alertdriver.FindElement(By.LinkText("See a sample confirm")).Click();//Wait for the alert to be displayedwait.Until(ExpectedConditions.AlertIsPresent());//Store the alert in a variableIAlertalert=driver.SwitchTo().Alert();//Store the alert in a variable for reusestringtext=alert.Text;//Press the Cancel buttonalert.Dismiss();
# Store the alert reference in a variablealert=driver.switch_to.alert# Get the text of the alertalert.text# Press on Cancel buttonalert.dismiss
//Click the link to activate the alert
driver.findElement(By.linkText("See a sample confirm")).click()//Wait for the alert to be displayed
wait.until(ExpectedConditions.alertIsPresent())//Store the alert in a variable
valalert=driver.switchTo().alert()//Store the alert in a variable for reuse
valtext=alert.text//Press the Cancel button
alert.dismiss()
Prompt
Prompts are similar to confirm boxes, except they also include a text
input. Similar to working with form elements, you can use WebDriver’s
send keys to fill in a response. This will completely replace the placeholder
text. Pressing the cancel button will not submit any text.
See a sample prompt.
alert=driver.switchTo().alert();//Store the alert text in a variable and verify ittext=alert.getText();assertEquals(text,"What is your name?");//Type your messagealert.sendKeys("Selenium");//Press the OK buttonalert.accept();
element=driver.find_element(By.LINK_TEXT,"See a sample prompt")driver.execute_script("arguments[0].click();",element)wait=WebDriverWait(driver,timeout=2)alert=wait.until(lambdad:d.switch_to.alert)alert.send_keys("Selenium")text=alert.textalert.accept()
//Click the link to activate the alertdriver.FindElement(By.LinkText("See a sample prompt")).Click();//Wait for the alert to be displayed and store it in a variableIAlertalert=wait.Until(ExpectedConditions.AlertIsPresent());//Type your messagealert.SendKeys("Selenium");//Press the OK buttonalert.Accept();
# Store the alert reference in a variablealert=driver.switch_to.alert# Type a messagealert.send_keys('selenium')# Press on Ok buttonalert.accept
//Click the link to activate the alert
driver.findElement(By.linkText("See a sample prompt")).click()//Wait for the alert to be displayed and store it in a variable
valalert=wait.until(ExpectedConditions.alertIsPresent())//Type your message
alert.sendKeys("Selenium")//Press the OK button
alert.accept()
3 - Working with cookies
A cookie is a small piece of data that is sent from a website and stored in your computer.
Cookies are mostly used to recognise the user and load the stored information.
WebDriver API provides a way to interact with cookies with built-in methods:
Add Cookie
It is used to add a cookie to the current browsing context.
Add Cookie only accepts a set of defined serializable JSON object. Here is the link to the list of accepted JSON key values
First of all, you need to be on the domain that the cookie will be
valid for. If you are trying to preset cookies before
you start interacting with a site and your homepage is large / takes a while to load
an alternative is to find a smaller page on the site (typically the 404 page is small,
e.g. http://example.com/some404page)
importorg.openqa.selenium.*;importorg.openqa.selenium.chrome.ChromeDriver;publicclassaddCookie{publicstaticvoidmain(String[]args){WebDriverdriver=newChromeDriver();try{driver.get("http://www.example.com");// Adds the cookie into current browser contextdriver.manage().addCookie(newCookie("key","value"));}finally{driver.quit();}}}

Get Named Cookie
It returns the serialized cookie data matching with the cookie name among all associated cookies.

Get All Cookies
It returns a ‘successful serialized cookie data’ for current browsing context.
If browser is no longer available it returns error.

Delete Cookie
It deletes the cookie data matching with the provided cookie name.

Same-Site Cookie Attribute
It allows a user to instruct browsers to control whether cookies
are sent along with the request initiated by third party sites.
It is introduced to prevent CSRF (Cross-Site Request Forgery) attacks.
Same-Site cookie attribute accepts two parameters as instructions
Strict:
When the sameSite attribute is set as Strict,
the cookie will not be sent along with
requests initiated by third party websites.
Lax:
When you set a cookie sameSite attribute to Lax,
the cookie will be sent along with the GET
request initiated by third party website.
Note: As of now this feature is landed in chrome(80+version),
Firefox(79+version) and works with Selenium 4 and later versions.

Frames are a now deprecated means of building a site layout from
multiple documents on the same domain. You are unlikely to work with
them unless you are working with an pre HTML5 webapp. Iframes allow
the insertion of a document from an entirely different domain, and are
still commonly used.
If you need to work with frames or iframes, WebDriver allows you to
work with them in the same way. Consider a button within an iframe.
If we inspect the element using the browser development tools, we might
see the following:
# This won't workdriver.find_element(:tag_name,'button').click
// This won't work
awaitdriver.findElement(By.css('button')).click();
//This won't work
driver.findElement(By.tagName("button")).click()
However, if there are no buttons outside of the iframe, you might
instead get a no such element error. This happens because Selenium is
only aware of the elements in the top level document. To interact with
the button, we will need to first switch to the frame, in a similar way
to how we switch windows.
WebDriver offers three ways of switching to a frame. Following example code
shows how we can do that, using a live web example.
Using a WebElement
Switching using a WebElement is the most flexible option. You can
find the frame using your preferred selector and switch to it.
//switch To IFrame using Web ElementWebElementiframe=driver.findElement(By.id("iframe1"));//Switch to the framedriver.switchTo().frame(iframe);assertEquals(true,driver.getPageSource().contains("We Leave From Here"));//Now we can type text into email fieldWebElementemailE=driver.findElement(By.id("email"));emailE.sendKeys("admin@selenium.dev");emailE.clear();
# Store iframe web elementiframe=driver.find_element(By.CSS_SELECTOR,"#modal > iframe")# switch to selected iframedriver.switch_to.frame(iframe)# Now click on buttondriver.find_element(By.TAG_NAME,'button').click()
//switch To IFrame using Web ElementIWebElementiframe=driver.FindElement(By.Id("iframe1"));//Switch to the framedriver.SwitchTo().Frame(iframe);Assert.AreEqual(true,driver.PageSource.Contains("We Leave From Here"));//Now we can type text into email fieldIWebElementemailE=driver.FindElement(By.Id("email"));emailE.SendKeys("admin@selenium.dev");emailE.Clear();
# Store iframe web elementiframe=driver.find_element(:css,'#modal > iframe')# Switch to the framedriver.switch_to.frameiframe# Now, Click on the buttondriver.find_element(:tag_name,'button').click
// Store the web element
constiframe=driver.findElement(By.css('#modal > iframe'));// Switch to the frame
awaitdriver.switchTo().frame(iframe);// Now we can click the button
awaitdriver.findElement(By.css('button')).click();
//Store the web element
valiframe=driver.findElement(By.cssSelector("#modal>iframe"))//Switch to the frame
driver.switchTo().frame(iframe)//Now we can click the button
driver.findElement(By.tagName("button")).click()
Using a name or ID
If your frame or iframe has an id or name attribute, this can be used
instead. If the name or ID is not unique on the page, then the first
one found will be switched to.
//switch To IFrame using name or iddriver.findElement(By.name("iframe1-name"));//Switch to the framedriver.switchTo().frame(iframe);assertEquals(true,driver.getPageSource().contains("We Leave From Here"));WebElementemail=driver.findElement(By.id("email"));//Now we can type text into email fieldemail.sendKeys("admin@selenium.dev");email.clear();
# Switch frame by iddriver.switch_to.frame('buttonframe')# Now, Click on the buttondriver.find_element(By.TAG_NAME,'button').click()
//switch To IFrame using name or iddriver.FindElement(By.Name("iframe1-name"));//Switch to the framedriver.SwitchTo().Frame(iframe);Assert.AreEqual(true,driver.PageSource.Contains("We Leave From Here"));IWebElementemail=driver.FindElement(By.Id("email"));//Now we can type text into email fieldemail.SendKeys("admin@selenium.dev");email.Clear();
# Switch by IDdriver.switch_to.frame'buttonframe'# Now, Click on the buttondriver.find_element(:tag_name,'button').click
// Using the ID
awaitdriver.switchTo().frame('buttonframe');// Or using the name instead
awaitdriver.switchTo().frame('myframe');// Now we can click the button
awaitdriver.findElement(By.css('button')).click();
//Using the ID
driver.switchTo().frame("buttonframe")//Or using the name instead
driver.switchTo().frame("myframe")//Now we can click the button
driver.findElement(By.tagName("button")).click()
Using an index
It is also possible to use the index of the frame, such as can be
queried using window.frames in JavaScript.
# Return to the top leveldriver.switch_to.default_content
// Return to the top level
awaitdriver.switchTo().defaultContent();
// Return to the top level
driver.switchTo().defaultContent()
5 - Print Page
Printing a webpage is a common task, whether for sharing information or maintaining archives.
Selenium simplifies this process through its PrintOptions, PrintsPage, and browsingContext
classes, which provide a flexible and intuitive interface for automating the printing of web pages.
These classes enable you to configure printing preferences, such as page layout, margins, and scaling,
ensuring that the output meets your specific requirements.
Configuring
Orientation
Using the getOrientation() and setOrientation() methods, you can get/set the page orientation — either PORTRAIT or LANDSCAPE.
deftest_orientation(driver):driver.get("https://www.selenium.dev/")print_options=PrintOptions()print_options.orientation="landscape"## landscape or portraitassertprint_options.orientation=="landscape"
publicvoidTestRange(){IWebDriverdriver=newChromeDriver();driver.Navigate().GoToUrl("https://selenium.dev");PrintOptionsprintOptions=newPrintOptions();printOptions.AddPageRangeToPrint("1-3");// add range of pagesprintOptions.AddPageToPrint(5);// add individual page}
deftest_size(driver):driver.get("https://www.selenium.dev/")print_options=PrintOptions()print_options.scale=0.5## 0.1 to 2.0``assertprint_options.scale==0.5
Using the getPageMargin() and setPageMargin() methods, you can set the margin sizes of the page you wish to print — i.e. top, bottom, left, and right margins.
deftest_scale(driver):driver.get("https://www.selenium.dev/")print_options=PrintOptions()print_options.scale=0.5## 0.1 to 2.0current_scale=print_options.scaleassertcurrent_scale==0.5
deftest_background(driver):driver.get("https://www.selenium.dev/")print_options=PrintOptions()print_options.background=True## True or Falseassertprint_options.backgroundisTrue
deftest_shrink_to_fit(driver):driver.get("https://www.selenium.dev/")print_options=PrintOptions()print_options.shrink_to_fit=True## True or Falseassertprint_options.shrink_to_fitisTrue
Once you’ve configured your PrintOptions, you’re ready to print the page. To do this,
you can invoke the print function, which generates a PDF representation of the web page.
The resulting PDF can be saved to your local storage for further use or distribution.
Using PrintsPage(), the print command will return the PDF data in base64-encoded format, which can be decoded
and written to a file in your desired location, and using BrowsingContext() will return a String.
There may currently be multiple implementations depending on your language of choice. For example, with Java you
have the ability to print using either BrowingContext() or PrintsPage(). Both take PrintOptions() objects as a
parameter.
Note: BrowsingContext() is part of Selenium’s BiDi implementation. To enable BiDi see Enabling Bidi
WebDriver does not make the distinction between windows and tabs. If
your site opens a new tab or window, Selenium will let you work with it
using a window handle. Each window has a unique identifier which remains
persistent in a single session. You can get the window handle of the
current window by using:
// Navigate to Urldriver.get("https://www.selenium.dev/selenium/web/window_switching_tests/page_with_frame.html");//fetch handle of thisStringcurrHandle=driver.getWindowHandle();assertNotNull(currHandle);
Clicking a link which opens in a
new window
will focus the new window or tab on screen, but WebDriver will not know which
window the Operating System considers active. To work with the new window
you will need to switch to it. For this, we fetch all window handles,
and store them in an array. The array position fills in the order the
window is launched. So first position will be default browser, and so on.
//click on link to open a new windowdriver.findElement(By.linkText("Open new window")).click();//fetch handles of all windows, there will be two, [0]- default, [1] - new windowObject[]windowHandles=driver.getWindowHandles().toArray();driver.switchTo().window((String)windowHandles[1]);//assert on title of new windowStringtitle=driver.getTitle();assertEquals("Simple Page",title);

for(windowHandleindriver.getWindowHandles()){if(!originalWindow.contentEquals(windowHandle)){driver.switchTo().window(windowHandle)break}}//Wait for the new tab to finish loading content
wait.until(titleIs("Selenium documentation"))
Closing a window or tab
When you are finished with a window or tab and it is not the
last window or tab open in your browser, you should close it and switch
back to the window you were using previously. Assuming you followed the
code sample in the previous section you will have the previous window
handle stored in a variable. Put this together and you will get:
#Close the tab or windowdriver.close#Switch back to the old tab or windowdriver.switch_to.windoworiginal_window
//Close the tab or window
awaitdriver.close();//Switch back to the old tab or window
awaitdriver.switchTo().window(originalWindow);
//Close the tab or window
driver.close()//Switch back to the old tab or window
driver.switchTo().window(originalWindow)
Forgetting to switch back to another window handle after closing a
window will leave WebDriver executing on the now closed page, and will
trigger a No Such Window Exception. You must switch
back to a valid window handle in order to continue execution.
Create new window (or) new tab and switch
Creates a new window (or) tab and will focus the new window or tab on screen.
You don’t need to switch to work with the new window (or) tab. If you have more than two windows
(or) tabs opened other than the new window, you can loop over both windows or tabs that WebDriver can see,
and switch to the one which is not the original.
Note: This feature works with Selenium 4 and later versions.
//Opens a new tab and switches to new tabdriver.switchTo().newWindow(WindowType.TAB);assertEquals("",driver.getTitle());//Opens a new window and switches to new windowdriver.switchTo().newWindow(WindowType.WINDOW);assertEquals("",driver.getTitle());
# Opens a new tab and switches to new tabdriver.switch_to.new_window('tab')# Opens a new window and switches to new windowdriver.switch_to.new_window('window')
// Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB)// Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW)
Quitting the browser at the end of a session
When you are finished with the browser session you should call quit,
instead of close:

* https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/AfterAll.html
*/@AfterAllpublicstaticvoidtearDown(){driver.quit();}

If not running WebDriver in a test context, you may consider using
try / finally which is offered by most languages so that an exception
will still clean up the WebDriver session.
Python’s WebDriver now supports the python context manager,
which when using the with keyword can automatically quit the driver at
the end of execution.

Window management
Screen resolution can impact how your web application renders, so
WebDriver provides mechanisms for moving and resizing the browser
window.

Web applications can enable a public key-based authentication mechanism known as Web Authentication to authenticate users in a passwordless manner.
Web Authentication defines APIs that allows a user to create a public-key credential and register it with an authenticator.
An authenticator can be a hardware device or a software entity that stores user’s public-key credentials and retrieves them on request.
As the name suggests, Virtual Authenticator emulates such authenticators for testing.
Virtual Authenticator Options
A Virtual Authenticatior has a set of properties.
These properties are mapped as VirtualAuthenticatorOptions in the Selenium bindings.
