Q5. What is the difference between implicit wait and explicit wait in selenium WebDriver?

Ans. When an implicit wait is implemented in tests, if WebDriver cannot find an element in the Document Object Model (DOM), it will wait for a defined amount of time for the element to appear in the DOM.

An explicit wait can be used where synchronization is needed, for example, the page is loaded but we are still waiting for a call to complete and an element to appear.

Q6. Which is better – implicit wait or explicit wait?

Ans. Explicit waits are better than implicit wait. Unlike an implicit wait, you can write custom code or conditions for wait before proceeding further in the code.

Q7. When should I use Selenium IDE?

Ans. Selenium IDE is the simplest of all the tools in the package and should be a great tool for naïve users as it is easy to learn with minimal acquaintances in the programming language.

Q8. Explain the difference between single (/) and a double slash (//) in X-path?

Ans. Single slash (/) allows the creation of ‘absolute’ path expressions, while double slash (//) allows the creation of ‘relative’ path expressions.

Q9. What is the use of XPath?

Ans. XPath is used to find the WebElement in web pages. It is also useful in identifying the dynamic elements.

Syntax:

Xpath=//tagname[@attribute=’value’]

• //: To select current node
• Tagname: Tagname of the given node
• @: To select attribute
• Attribute: Attribute name of the node
• Value: Value of the attribute

Q10. What is the difference between type keys and type commands?

Ans. Type key populates the value attribute using JavaScript whereas type commands emulate actual user typing.

Q11. What is the difference between verify and assert commands?

Ans. Assert command allows us to check whether an element is on the page or not. Verify command checks whether the element is on the page, otherwise, the test will carry on executing.

Q12. What are heightened privilege browsers?

Ans. Heightened privileges browsers are similar to Proxy Injection, allowing websites to do something that is not commonly permitted.

Q13. Explain what is Data-driven framework and Keyword driven?

Ans. In a Data-driven framework, the test data is separated and kept outside the Test Scripts, while test case logic resides in Test Scripts.

Keyword-driven frameworks require the development of data tables and keywords, independent of the test automation.

Q14. What is Object Repository?

Ans. Object repository is an essential entity in any UI automation that allows a tester to store all objects that will be used in the scripts in one or more centralized locations rather than scattered all over the test scripts.

Q15. Mention 5 different exceptions you had in Selenium WebDriver?

Ans. The 5 different exceptions in Selenium WebDriver are WebDriver Exception, NoAlertPresentException, NoSuchWindowException, NoSuchElementException, TimeoutException

Q16. Which web driver implementation is the fastest?

Ans. HTMLUnit Driver implementation is the fastest

Q17. How to find more than one web element in the list?

Ans. It can be done using WebElement List. E.g.

List <WebElement> elementList = driver.findElements(By.xpath(“//div[@id=’example’]//ul//li”));   int listSize = elementList.size(); for (int i=0; i<listSize; i++) { serviceProviderLinks.get(i).click(); driver.navigate().back(); }

Q18. What is the difference between driver.close() and driver.quit() command?

Ans. Close() method closes the web browser window that the user is currently working on or the browser that WebDriver is currently accessing.

Quit() method closes down all the windows that the program has opened.

Q19. In which format does the source view show your script in Selenium IDE?

Ans. XML

Q20. What is Object Repository? How can we create an Object Repository in Selenium?

Ans. Object Repository is a term used to refer to the collection of web elements belonging to Application Under Test (AUT) along with their locator values.

In Selenium, objects can be stored in an excel sheet that can be populated inside the script whenever required.

Q21. Explain how to navigate to a new window from the current window?

Ans. To navigate to a new window from the current window, you can use:

driver.navigate().to(new window url) method

Q22. How can you convert any Selenium IDE tests from Selenese to another language?

Q25. In Selenium, what are Breakpoints and Startpoints?

Ans. A breakpoint is implemented to stop execution to check if the code is working as expected till now.

A startpoint indicates the point from where the execution should begin.

Q26. What are the components of the Selenium suite?

Ans. Selenium suite has four major components:

1. Selenium IDE (Integrated Development Environment)

It is an important tool in the Selenium Suite. It is a complete integrated development environment (IDE) for Selenium tests. It is implemented as a Firefox/Chrome plug-in and speeds up the creation of automation scripts. Selenium IDE allows for recording, editing, and debugging of functional tests. To create an advanced framework, Selenium IDE has to be combined with Selenium WebDriver or Selenium Remote Control (RC).

2. Selenium Remote Control (RC)

It is a server that allows users to write test scripts in multiple programming languages and browsers which results in better integration of Selenium in existing unit test frameworks. It accepts the commands from the test script and sends them to the browser as Selenium core JavaScript commands. The browser then behaves accordingly.

3. Selenium WebDriver

It is a tool that helps create and run test cases. It supports various platforms like Windows, Mac, and Linux and several browsers like Chrome, IE, Safari, and Firefox. The WebDriver can be written on languages like Java, Python, C#, Ruby. It overcomes the disadvantages of Selenium RC as it does not require an additional server and communicates natively with the browser and runs on it.

4. Grid

Selenium Grid is a server that allows tests to use web browser instances running on remote machines. Grid is exceptionally flexible and is integrated with other suite components for simultaneous execution or parallel execution. It works with Selenium RC to run test cases concurrently in multiple machines, browsers, and platforms.

Q27. Can you tell from where the term Selenium derived?

Ans. Well, it came from a joke made by Jason Huggins (the developer of Selenium) in an email, where he mocked one of his competitors named Mercury, saying that you can cure mercury poisoning by taking selenium supplements. This is from where the other email recipients took the name and the rest is history.

Learn about software testing, read our blog – what is Software Testing?

Q28. Why should you use Selenium as a test tool?

Ans. Selenium is a free and open-source tool and has a large user base. It helps communities and is compatible with every browser (Chrome, Firefox, Internet Explorer, etc.). Besides, it also has great platform compatibility (Windows, Mac OS, Linux, etc.)

Q29. What is Selenese?

Ans. Selenese is a set of selenium commands which are used for testing a web application. It is the language used for writing test scripts in Selenium IDE. Using Selenese, a tester can test the broken links, Ajax functionality, Alerts, window, list options, etc. 

There are three types of commands used in Selenese – 

1. Actions:

These are the commands that interact directly with web applications. They change the state of the application, such as click on some link, select a value from the drop-down, etc. For example: Click and DoubleClick. 

2. Accessors:

These commands check the state of the application and store the application state in a user-defined variable. For example: storeTitle and storeTextPresent. 

3. Assertions:

These commands check the state of application against the expected conditions. They add a checkpoint or verification in the automation tests. There are three modes in assertions, namely verify, assert and waitfor. For example: assertText, assertTitle, verifyText, and verifyTitle. 

Q30. What is the difference between automation testing and manual testing?

Ans. The difference between automation testing and manual testing is:

Automation testing	Manual testing
Automated testing is faster and reliable than manual testing.	Manual testing takes a lot of time and human effort.
It is a more accurate method, as it uses tools and scripts.	It is not that accurate because of human errors.
It does not allow random testing.	Exploratory testing can be done in manual testing.
It is not cost-effective for low volume regression	It is not cost-effective for high-volume regression.
Programming knowledge is required in automation testing.	Programming knowledge is not required in manual testing.

Q31. How do we launch a batch file in a Selenium Webdriver project?

Ans. It uses a test suite to execute a batch file and also takes an executable file to set up the process before the automation. Below code can be used to initiate the process:

Process batch = Runtime.getRuntime.exec(“path of the batch file”);

batch.waitFor();

Q32. Elaborate on the functioning of Selenium Grid?

Ans. Selenium Grid sends tests to the hub, which are then redirected to Selenium Webdriver. It then launches the browser and runs the test. The tests run in parallel with the entire test suite.

Q33. Can we use the Selenium grid for performance testing?

Ans. Yes, but it is not as effective as Loadrunner, which is a dedicated Performance Testing tool.

Q34. Is it possible to replace automation testing with manual testing?

Ans. Automation testing cannot fully replace manual testing as it is not possible to expect test automation to bring off all the work done by manual testing.

Q35. How will you find an element using Selenium?

Ans. Every object or control in a web page is an element in Selenium, and some of the ways to find that element in a web page include user ID, Name, Tag, Attribute, CSS, Linktext, PartialLink Text, and Xpath.

Q36. What is the Page Object Model (POM)?

Ans. POM is a design pattern responsible for creating an Object Repository for web UI elements.

Q37. What is Page Factory?

Ans. Page Factory provides an optimized way to implement Page Object Model and it has a very good memory utilization and implementation is object-oriented.

Q38. What is an XPath?

Ans. XPath is a language that helps to locate and process items in Extensible Markup Language (XML) documents. It addresses syntax based on a path through the document’s logical structure or hierarchy. XPath is used to locate a web element based on its XML path. It also stores, organizes, and transports arbitrary data.

Q39. Name different types of XPath?

Ans. There are two types of XPath:

• Absolute XPath

Syntax: html/body/div[1]/section/div[1]/div/div/div/div[1]/div/div/div/div/div[3]/div[1]/div/h4[1]/b

• Relative Xpath

Syntax: 

//*[@class=’featured-box’]//*[text()=’Testing’]

Q40. How do we run the selenium IDE test suite from the command line?

Ans. We can use the below command to run the test suite:

Syntax: 

Java -jar “C:\Selenium Webdriver Questions\selenium-server-standalone-2.33.0.jar” -htmlSuite “*firefox” “http://www.google.com” ” “C:\Selenium Webdriver Questions\SeleniumSuite.HTML”

Q41. How can we perform drag and drop action in Selenium WebDriver?

Ans. We can use the advanced user interaction API to perform drag and drop operations:

Example:

Actions act = new Actions(driver);

act.dragAndDrop(source_locator, target_locator).build().perform();

Q42. Name the Selenese command that is used to present the value of a variable?

Ans. echo() is the command used for presenting the variable value.

Q43. Can Selenium handle windows based pop up?

Ans. Since it is an automation testing tool and supports only web application testing, it can’t handle windows pop up. However, third-party tools like AutoITm and Robot class are available to handle this.

Must Check: Python Interview Questions and Answer

Q44. How do we handle web-based pop up in Selenium?

Ans. We can use WebDriver, which provides an efficient way to handle these pop-ups using the Alert interface. Besides, there are four methods too that we can use –

void dismiss() – The accept() method clicks on the “Cancel” button when the pop-up window appears.

void accept() – The accept() method clicks on the “Ok” button when the pop-up window appears.

String getText() – The getText() method returns the text displayed on the alert box.

void sendKeys(String stringToSend) – The sendKeys() method enters the specified string pattern into the alert box.

Syntax:   // accepting javascript alert Alert alert = driver.switchTo().alert(); alert.accept();

Q45. Tell me how can I take a screenshot in Selenium WebDriver?

Ans. You can do that by using the TakeScreenshot function and by using getScreenshotAs() method, you can save the screenshot.

Q46. Is it possible to enter a text without using sendKeys()?

Ans. Yes, we can enter/ send a text using JavaScriptExecutor, and we don’t need to use sendKeys() method.

Q47. What is Junit? What are Junit annotations?

Ans. It is a Java-based unit testing framework introduced by Apache. It is an open-source Framework that offers integrations with IDEs such as Eclipse, IntelliJ, etc., allowing you to execute unit testing easily. 

JUnit Annotations help identify the type of methods we have defined in our test code. Following are some of the common JUnit Annotations:

• @BeforeClass: It lets the system know that this method shall be invoked only once before any of the test methods.
• @Before: It denotes that the method shall be executed every time before each of the test methods.
• @Test: It denotes that the method annotated as @Test is a test method. It does not take any attributes. There can be multiple test methods in a single test script.
• @After: It denotes that the method shall be executed every time after each of the test methods.
• @AfterClass: It tells the system that this method shall be executed once after any of the test methods.
• @Ignore: It denotes that this method shall not be executed.

Some of the JUnit Annotations for specific purposes are @ParameterizedTest,  @RunWith, @RepeatedTest, and @Parameters.

Q53. What is an absolute XPath?

Ans. Absolute XPath locates an element using XML expression that starts from the root node or with ‘/’. It contains the complete path of all the elements, including the root element, as well as the desired element. Absolute XPath has a significant disadvantage, which is if there is even a minor change in the UI, the entire XPath fails.

Q54. What is a Relative XPath?

Ans. Relative XPath locates an element using XML expression, beginning from anywhere in the HTML document. This is used to create robust XPaths, which remain unaffected by changes in other UI elements.

Q55. How do we identify a child element using XPath?

Ans. To identify a child element using XPath, we can use the below code:

Syntax: //div/a

Q56. How to use CSS Selector for identifying web elements by class?

Ans. To identify web elements by their class, we can use .className and select elements belonging to that particular class. Apart from this, a CSS selector can locate web elements with ID, class, or name.

Q57. How to use CSS Selector for identifying web elements by ID?

Ans. To identify web elements by ID, we can use #idValue and select elements belonging to that particular ID.

Q58. How to use CSS Selector for identifying web elements by their attribute value?

Ans. To identify web elements by their attribute value, we can use [attribute=value] to select elements belonging to that particular attribute type.

Q59. How can we move to nth child element using the CSS Selector?

Q67. What is a data-driven framework?

Ans. Data-driven is a test automation framework. It stores test data in a spread spreadsheet or table format such as MS Excel Sheets, MS Access Tables, SQL Database, XML files, etc. separated from test logic written in test script files. Data-Driven Testing enables engineers to execute tests for each set of test data values.

Q68. What is a keyword-driven framework?

Ans. A keyword-driven framework is a type of Functional Automation Testing Framework, and it works on action word-based testing. The keyword-driven framework helps to accelerate automated testing by using keywords related to the application being tested. These keywords should be included in every input to describe actions to be performed for each step and execute the test successfully.

Q69. What is a hybrid framework?

Ans. As the name suggests, a hybrid framework is a combination of one or more frameworks and is a combination of data-driven and keyword-driven frameworks. Here the test data and test actions are kept in external files. This implements the Page Object Model Technique, Data-Driven Technique, Modular Driven Technique, Log4j Logging, TestNG Reporting, and TestNG Reporter Logs.

Q70. What is Selenium 2.0, and how is it better than Selenium 1.0?

Ans. Selenium 1 is known as Selenium Remote Control (RC). Selenium 2.0 is a combination of Selenium 1 and WebDriver, making it superior to RC. Selenium 2 is also popularly known as Selenium WebDriver that directly sends commands to the browser instead of sending it to a server. Selenium 2.0 runs the JavaScript natively; thus there is a need to write the test once, and Selenium will test on different browsers.

To learn more about Selenium, read our blog – what is Selenium?

Q71. What is Selenium 3.0, and how is it better than Selenium 2.0?

Q73. Can you explain how we can make two test methods dependent on each other using TestNG?

Ans. There is a feature in TestNG, dependency, which allows a test method to depend on other test methods. Dependency is configured by using the dependent test method separated by commas to the attribute dependsOnMethods. This is done while using test annotation on multiple test methods.

@Test(dependsOnMethods = { “preTests” })

Q74. What is the difference between “type” and “typeAndWait” commands in terms of Selenium?

Ans.“Type” command is used for entering keyboard key values into the text box of a software web application. It is also used for choosing values from a combo box. On the other hand, “typeAndWait” is used once you finish typing and when the software web page begins to reload. This command waits for the software program page to reload before proceeding. You will have to use the basic “type” command in case there is no page reload event while typing.
