  • Supports execution of repeated test cases
  • Aids in testing a large test matrix
  • Enables parallel execution
  • Encourages unattended execution
  • Improves accuracy thereby reducing human-generated errors
  • Saves time and money

Why should Selenium be selected as a test tool?
Ans: Selenium is a free and open-source have a large user base and helping communities have cross Browser compatibility (Firefox, Chrome, Internet Explorer, Safari etc.) have great platform compatibility (Windows, Mac OS, Linux etc.) supports multiple programming languages (Java, C#, Ruby, Python, Pearl etc.) has fresh and regular repository developments supports distributed testing

What is Selenium? What are the different Selenium components?
Ans: Selenium is one of the most popular automated testing suites. Selenium is designed in a way to support and encourage automation testing of functional aspects of web-based applications and a wide range of browsers and platforms. Due to its existence in the open-source community, it has become one of the most accepted tools amongst the testing professionals. Selenium is not just a single tool or a utility, rather a package of several testing tools and for the same reason, it is referred to as a Suite. Each of these tools is designed to cater to different testing and test environment requirements. The suite package constitutes the following sets of tools:

  • Selenium Integrated Development Environment (IDE) – Selenium IDE is a record and playback tool. It is distributed as a Firefox Plugin.
  • Selenium Remote Control (RC) – Selenium RC is a server that allows a user to create test scripts in the desired programming language. It also allows executing test scripts within the large spectrum of browsers.
  • Selenium WebDriver – WebDriver is a different tool altogether that has various advantages over Selenium RC. WebDriver directly communicates with the web browser and uses its native compatibility to automate.
  • Selenium Grid – Selenium Grid is used to distribute your test execution on multiple platforms and environments concurrently.

What are the testing types that can be supported by Selenium?
Ans: Selenium supports the following types of testing:
Functional Testing
Regression Testing

What are the limitations of Selenium?
Ans: Following are the limitations of Selenium:

  • Selenium supports the testing of only web-based applications
  • Mobile applications cannot be tested using Selenium
  • Captcha and Barcode readers cannot be tested using Selenium
  • Reports can only be generated using third-party tools like TestNG or Junit.
  • Selenium is a free tool. Thus there is no ready vendor support through the user can find numerous helping communities.
  • A user is expected to possess prior programming language knowledge.

When should I use Selenium IDE?
Ans: Selenium IDE is the simplest and easiest of all the tools within the Selenium Package. Its record and playback feature make it exceptionally easy to learn with minimal acquaintances to any programming language. Selenium IDE is an ideal tool for a naïve user.

What is Selenese?
Ans: Selenese is the language which is used to write test scripts in Selenium IDE.

What are the different types of locators in Selenium?
Ans: Locator can be termed as an address that identifies a web element uniquely within the webpage. Thus, to identify web elements accurately and precisely, we have different types of locators in Selenium:

  • ID
  • ClassName
  • Name
  • TagName
  • LinkText
  • PartialLinkText
  • Xpath
  • CSS Selector
  • DOM

What is the difference between Assert and verify commands?
Ans:

  • Assert: Assert command checks whether the given condition is true or false. Let’s say we assert whether the given element is present on the web page or not. If the condition is true, then the program control will execute the next test step, but if the condition is false, the execution will stop, and no further test would be executed.
  • Verify: Verify command also checks whether the given condition is true or false. Irrespective of the condition being true or false, the program execution doesn’t halt, i.e. any failure during verification would not stop the execution, and all the test steps would be executed.

What is an XPath?
Ans: XPath is used to locate a web element based on its XML path. XML stands for Extensible Markup Language and is used to store, organise and transport arbitrary data. It stores data in a key-value pair which is very much similar to HTML tags. Both being markup languages and since they fall under the same umbrella, XPath can be used to locate HTML elements.

The fundamental behind locating elements using XPath is the traversing between various elements across the entire page and thus enabling a user to find an element with the reference of another element.

What is the difference between “/” and “//” in XPath?
Ans:

  • Single Slash “/” – Single slash is used to create XPath with an absolute path, i.e. the XPath would be created to start selection from the document node/start node.
  • Double Slash “//” – Double slash is used to create XPath with a relative path, i.e. the XPath would be created to start selection from anywhere within the document.

What is the Same-origin policy and how it can be handled?
Ans: The problem of same-origin policy disallows to access the DOM of a document from an origin that is different from the origin we are trying to access the document.
Origin is a sequential combination of scheme, host, and port of the URL. For example, for a URL HTTP:// http://www.softwaretestingo.com/selenium/, the origin is a combination of HTTP, softwaretestingo.com, 80 correspondingly.
Thus the Selenium Core (JavaScript Program) cannot access the elements from an origin that is different from where it was launched. For Example, if I have launched the JavaScript Program from “http://www.softwaretestingo.com”, then I would be able to access the pages within the same domain such as “http://www.softwaretestingblog.in/selenium” or “http://www.softwaretestingo.com/manual/”. The other domains, like google.com, seleniumhq.org would no more be accessible.
So, To handle the same-origin policy, Selenium Remote Control was introduced.

When should I use Selenium Grid?
Ans: Selenium Grid can be used to execute same or different test scripts on multiple platforms and browsers concurrently to achieve distributed test execution, testing under different environments and saving execution time remarkably.

What do we mean by Selenium 1 and Selenium 2?
Ans: Selenium RC and WebDriver, in a combination, are popularly known as Selenium 2. Selenium RC alone is also referred to as Selenium 1.

Which is the latest Selenium tool?
Ans: WebDriver

How do I launch the browser using WebDriver?
Ans: The following syntax can be used to launch Browser:
WebDriver driver = new FirefoxDriver();
WebDriver driver = new ChromeDriver();
WebDriver driver = new InternetExplorerDriver();

What are the different types of Drivers available in WebDriver?
Ans: The different drivers available in WebDriver are:

  • FirefoxDriver
  • InternetExplorerDriver
  • ChromeDriver
  • SafariDriver
  • OperaDriver
  • AndroidDriver
  • IPhoneDriver
  • HtmlUnitDriver

What are the different types of waits available in WebDriver?
Ans: There are two types of waits available in WebDriver:
Implicit Wait
Explicit Wait

  • Implicit Wait: Implicit waits are used to provide a default waiting time (say 30 seconds) between each consecutive test step/command across the entire test script. Thus, the subsequent test step would only execute when the 30 seconds have elapsed after executing the previous test step/command.
  • Explicit Wait: Explicit waits are used to halt the execution until the time a particular condition is met or the maximum time has elapsed. Unlike Implicit waits, explicit waits are applied for a particular instance only.

How to type in a textbox using Selenium?
Ans: User can use sendKeys(“String to be entered”) to enter the string in the textbox.
Syntax:
WebElement username = drv.findElement(By.id(“Email”));
// entering username
username.sendKeys(“sth”);

How can you find if an element in displayed on the screen?
Ans: WebDriver facilitates the user with the following methods to check the visibility of the web elements. These web elements can be buttons, drop boxes, checkboxes, radio buttons, labels etc.
isDisplayed()
isSelected()
isEnabled()
Syntax:

isDisplayed():

boolean buttonPresence = driver.findElement(By.id(“gbqfba”)).isDisplayed();

isSelected():

boolean buttonSelected = driver.findElement(By.id(“gbqfba”)).isSelected();

isEnabled():

boolean searchIconEnabled = driver.findElement(By.id(“gbqfb”)).isEnabled();

How can we get a text of a web element?
Ans: Get command is used to retrieve the inner text of the specified web element. The command doesn’t require any parameter but returns a string value. It is also one of the extensively used commands for verification of messages, labels, errors etc. displayed on the web pages.
Syntax:
String Text = driver.findElement(By.id(“Text”)).getText();

How to select value in a dropdown?
Ans: Value in the dropdown can be selected using WebDriver’s Select class.
Syntax:

selectByValue:

Select selectByValue = new Select(driver.findElement(By.id(“SelectID_One”))); selectByValue.selectByValue(“greenvalue”); 

selectByVisibleText:

Select selectByVisibleText = new Select (driver.findElement(By.id(“SelectID_Two”))); selectByVisibleText.selectByVisibleText(“Lime”);

selectByIndex:

Select selectByIndex = new Select(driver.findElement(By.id(“SelectID_Three”))); selectByIndex.selectByIndex(2);

What are the different types of navigation commands?
Ans: Following are the navigation commands:

  • navigate().back() – The above command requires no parameters and takes back the user to the previous webpage in the web browser’s history.
    Sample code:
    driver.navigate().back();
  • navigate().forward() – This command lets the user to navigate to the next web page with reference to the browser’s history.
    Sample code:
    driver.navigate().forward();
  • navigate().refresh() – This command lets the user to refresh the current web page there by reloading all the web elements.
    Sample code:
    driver.navigate().refresh();
  • navigate().to() – This command lets the user to launch a new web browser window and navigate to the specified URL.
    Sample code:
    driver.navigate().to(“https://google.com”);

How to click on a hyperlink using linkText?
Ans: driver.findElement(By.linkText(“Google”)).click();
The command finds the element using link text and then click on that element, and thus the user would be re-directed to the corresponding page.
The above-mentioned link can also be accessed by using the following command.
driver.findElement (By.partialLinkText(“Goo”)).click();
The above command finds the element based on the substring of the link provided in the parenthesis and thus partialLinkText() finds the web element with the specified substring and then clicks on it.

How to handle frame in WebDriver?
Ans: An inline frame acronym as iframe is used to insert another document within the current HTML document or simply a web page into a web page by enabling nesting.

  • Select iframe by id
    driver.switchTo().frame(“ID of the frame“);
  • Locating iframe using tagName
    driver.switchTo().frame (driver.findElements (By.tagName(“iframe”).get(0));
  • Locating iframe using index
    frame(index)
    driver.switchTo().frame(0);
  • frame(Name of Frame)
    driver.switchTo().frame(“name of the frame”);
    frame(WebElement element)
    Select Parent Window
    driver.switchTo().defaultContent();

When do we use findElement() and findElements()?
Ans:

findElement(): findElement() is used to find the first element in the current web page matching the specified locator value. Take note that only the first matching element would be fetched.
Syntax:

WebElement element = driver.findElements(By.xpath(“//div[@id=’example’]//ul//li”));

findElements(): findElements() is used to find all the elements in the current web page matching to the specified locator value. Take a note that all the matching elements would be fetched and stored in the list of WebElements.
Syntax:

List <WebElement> elementList = driver.findElements(By.xpath(“//div[@id=’example’]//ul//li”));

How to find more than one web element in the list?
Ans: At times, we may come across elements of the same type of multiple hyperlinks, images etc. arranged in an ordered or unordered list. Thus, it makes absolute sense to deal with such elements by a single piece of code, and this can be done using the WebElement List.
Sample Code

// Storing the list
List <WebElement> elementList = driver.findElements(By.xpath("//div[@id='example']//ul//li"));
// Fetching the size of the list
int listSize = elementList.size();
for (int i=0; i<listSize; i++)
{
   // Clicking on each service provider link
   serviceProviderLinks.get(i).click();
   // Navigating back to the previous page that stores link to service providers
   driver.navigate().back();
}

What is the difference between driver.close() and driver.quit command?
Ans:

  • Close (): WebDriver’s close() method closes the web browser window that the user is currently working on or we can also say the window that is being currently accessed by the WebDriver. The command neither requires any parameter, nor does it return any value.
  • Quit (): Unlike a close() method, quit() method closes down all the windows that the program has opened. The same as the close() method, the command neither requires any parameter nor does it return any value.

Can Selenium handle windows based pop up?
Ans: Selenium is an automation testing tool which supports only web application testing. Therefore, windows pop up cannot be handled using Selenium.

How can we handle web-based pop-up?
Ans: WebDriver offers the users with a very efficient way to handle these pop-ups using Alert interface. There are four methods that we would be using along with the Alert interface.

  • Void dismiss() – The accept() method clicks on the “Cancel” button as soon as the pop-up window appears.
  • Void accept() – The accept() method clicks on the “Ok” button as soon as the pop-up window appears.
  • String getText() – The getText() method returns
