Xoriant Interview Questions and Answers

Our automation framework is built using Selenium WebDriver and TestNG.

• We use Page Object Model design pattern for better maintainability.

• We have created custom libraries for common functions like login, logout, etc.

• We use Jenkins for continuous integration and execution of automated tests.

• We have implemented data-driven testing using Excel sheets.

• We use Git for version control and collaboration among team members.

TestNG annotations are executed in a specific sequence during test execution.

• BeforeSuite

• BeforeTest

• BeforeClass

• BeforeMethod

• Test

• AfterMethod

• AfterClass

• AfterTest

• AfterSuite

Failed test screenshots can be taken using automation tools and saved in a designated folder.

• Use automation tools like Selenium or Appium to capture screenshots on test failure

• Save the screenshots in a designated folder for easy access and reference

• Include the screenshot file name in the test report for better traceability

GetOption() method is used to retrieve the value of a selected option in a dropdown list.

• GetOption() method is commonly used in automated testing to verify if the correct option is selected in a dropdown list.

• The method returns the value of the selected option as a string.

• If no option is selected, the method returns null or an empty string.

Different types of exceptions include checked, unchecked, runtime, and error.

• Checked exceptions are checked at compile time and must be handled or declared.

• Unchecked exceptions are not checked at compile time and do not need to be handled or declared.

• Runtime exceptions are unchecked exceptions that occur during runtime.

• Errors are serious problems that cannot be handled by the program, such as OutOfMemoryError.

Alerts can be handled using Alert interface in Selenium

• Use driver.switchTo().alert() method to switch to alert

• Use getText() method to get the text of the alert

• Use accept() method to click on OK button of the alert

• Use dismiss() method to click on Cancel button of the alert

Asserts are used to verify expected results in automated tests. There are various types of asserts.

• Assert.AreEqual - compares two values for equality

• Assert.IsTrue/False - checks if a condition is true/false

• Assert.IsNull/NotNull - checks if a value is null/not null

• Assert.ThrowsException - checks if an exception is thrown

• Assert.AreSame - checks if two objects refer to the same instance

• Assert.AreNotSame - checks if two ob

To handle Iframe, switch to the frame using driver.switchTo().frame() method.

• Identify the Iframe using its ID, name, or index

• Switch to the Iframe using driver.switchTo().frame() method

• Perform the required actions inside the Iframe

• Switch back to the default content using driver.switchTo().defaultContent() method

To switch default frame in automation testing, use switchTo() method of WebDriver class.

• Use driver.switchTo().frame() method to switch to a specific frame by index, name, or WebElement.

• Use driver.switchTo().defaultContent() method to switch back to the default content.

• Example: driver.switchTo().frame(0); //switch to first frame

• Example: driver.switchTo().frame("frameName"); //switch to frame with name "frameName"

Test with priority 1 executes first, followed by 0 and then -1.

• Tests with higher priority are executed first

• Priority can be used to determine the order of execution

• Priority can be set in test management tools like JIRA or TestRail

To take multiple values from dropdown, use a loop to iterate through each option and select them.

• Identify the dropdown element using its locator

• Use the Select class to create an object for the dropdown

• Use the getOptions() method to get all the options in the dropdown

• Iterate through the options using a loop and select each option using the selectByVisibleText() or selectByValue() method

ElementNotPresent exception occurs even if element is present on page. Why?

• The element may not be loaded yet, so wait for it to load before checking

• The element may be hidden or not visible on the page

• The element may have a different name or ID than expected

• The element may be in an iframe or shadow DOM

• The element may have been removed or deleted from the page

Key topics in Generative AI include Retrieval-Augmented Generation (RAG) and Large Language Models (LLM).

• RAG combines generative models with retrieval mechanisms to improve text generation.

• LLMs like GPT-3 and BERT are pre-trained on large text corpora to generate human-like text.

• Ethical considerations in using LLMs for text generation, such as bias and misinformation.

• Applications of RAG and LLMs in natural language pro...read more
