LTIMindtree Quality Assurance and Automation Tester Interview Questions, Process, and Tips

The @BeforeMethod annotation is used to run a method before each test method in a class, while @BeforeTest is used to run a method before any test method in a test tag.

• The @BeforeMethod annotation is specific to TestNG framework and is used to initialize test data before each test method.

• @BeforeTest annotation is also specific to TestNG and is used to initialize test data before any test method in a test tag.

Java program to print sum of digits from a given string

• Iterate through each character in the string

• Check if the character is a digit using Character.isDigit() method

• Convert the digit character to integer using Character.getNumericValue() method

• Sum up all the digits found in the string

OOPs concepts used in the framework include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance is used to create a parent-child relationship between classes. For example, a base class 'Page' can be inherited by 'HomePage' and 'LoginPage' classes.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass. For instance, a 'click' method can be implemented different...read more

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example of compile-time polymorphism: function overloading in Java.

• Example of runtime polymorphism: method overriding in Java

Java program to print the sum of elements in a string array.

• Convert each element in the string array to an integer using Integer.parseInt()

• Sum up all the integers to get the total sum

We are using the Selenium framework for automation testing in our project.

• Selenium is a popular open-source automation testing framework

• It supports multiple programming languages like Java, Python, C#, etc.

• Selenium WebDriver is used for automating web applications

• It provides features for browser automation, testing across different browsers, and parallel test execution

Framework structure refers to the organization and layout of the automation framework components.

• Framework structure includes modules, libraries, test scripts, configuration files, and test data.

• It follows a hierarchical structure with layers such as driver scripts, reusable libraries, and test cases.

• Frameworks can be structured as linear, modular, data-driven, keyword-driven, or hybrid.

• Example: In a data-driven framew...read more

findelement returns the first matching element on a webpage, findelements returns a list of all matching elements.

• findelement returns a single WebElement, findelements returns a list of WebElements

• findelement throws NoSuchElementException if no element is found, findelements returns an empty list

• Example: driver.findElement(By.id("exampleId")) vs driver.findElements(By.className("exampleClass"))

Handling multiple tabs in Selenium involves switching between tabs and performing actions on each tab.

• Use getWindowHandles() to get a set of window handles

• Switch to a specific tab using switchTo().window(handle)

• Perform actions on the tab

• Close the tab if needed using driver.close()

Hashmaps are data structures that store key-value pairs and allow for efficient retrieval of values based on keys.

• Hashmaps are also known as dictionaries, maps, or associative arrays.

• They use a hash function to map keys to indices in an underlying array.

• Hashmaps offer constant-time average case complexity for insertion, deletion, and lookup operations.

• Example: HashMap map = new HashMap<>(); map.put("ke

Try and catch blocks are used in programming to handle exceptions and prevent the program from crashing.

• Try block is used to enclose the code that might throw an exception

• Catch block is used to handle the exception thrown in the try block

• It prevents the program from crashing and allows for graceful error handling

• Can also include finally block to execute code regardless of whether an exception is thrown

Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.

• Allows a class to inherit attributes and methods from another class

• Promotes code reusability and reduces redundancy

• Creates a parent-child relationship between classes

• Derived class can access the properties and methods of the base class

• Example: Class 'Car' can inherit from class 'Vehicle'

API testing involves testing the functionality, reliability, performance, and security of APIs.

• Testing API endpoints for correct response codes and data

• Verifying data accuracy and consistency in API responses

• Testing API security measures such as authentication and authorization

• Performance testing to ensure APIs can handle expected load

• Exploratory testing to uncover potential issues

Given When Then is implemented in BDD framework by writing scenarios in a structured format to define behavior

• BDD frameworks like Cucumber use Given When Then to structure scenarios

• Given describes the initial state of the system

• When describes the action taken by the user

• Then describes the expected outcome or result

• Example: Given a user is logged in, When they click on the 'Logout' button, Then they should be logged out

Gherkin words are keywords used in Gherkin syntax for writing test scenarios in Behavior Driven Development (BDD).

• Feature

• Scenario

• Given

• When

• Then

• And

• But

Plugins are used to extend the functionality of a software application.

• Plugins are additional software components that can be added to an existing application to provide new features or functionalities.

• They can be used to customize the behavior of the application without modifying its core code.

• Examples of plugins include browser extensions, WordPress plugins, and Adobe Photoshop filters.

To run a runner class, you can use a test runner tool like JUnit or TestNG in your automation testing framework.

• Use a test runner tool like JUnit or TestNG to execute the runner class

• Add the @RunWith annotation in JUnit or specify the runner class in TestNG XML file

• Make sure the runner class includes the necessary setup and teardown methods for test execution

TestNG allows running tests in parallel mode using groups and priorities.

• Use 'parallel' attribute in testng.xml file to specify parallel mode (e.g. )

• Use 'groups' attribute in testng.xml file to group tests that should run in parallel (e.g. )

• Use 'priority' attribute in testng.xml file to specify the order in which tests should run (e.g.

Merge Sort is a divide and conquer algorithm that divides the input array into two halves, sorts them, and then merges them back together.

• Divide the array into two halves recursively

• Sort each half using Merge Sort recursively

• Merge the sorted halves back together

Program to reverse a string using array of characters

• Create an array of characters from the input string

• Iterate through the array in reverse order and append each character to a new string

• Return the reversed string

Data driven testing syntax using XSSF Workbook

• Create XSSFWorkbook object

• Get the sheet from the workbook

• Iterate through rows and columns to fetch test data

• Use test data in your test cases

Reverse a string in Java using StringBuilder's reverse method.

• Create a StringBuilder object with the input string

• Use the reverse() method of StringBuilder to reverse the string

• Convert the reversed StringBuilder object back to a string using toString()

An interface in software development is a contract that defines the methods that a class must implement.

• Interfaces in programming languages like Java, C#, and TypeScript provide a way to achieve abstraction and multiple inheritance.

• Classes implementing an interface must provide concrete implementations for all the methods defined in the interface.

• Interfaces allow for loose coupling between components, making code more
