Maven build lifecycle consists of phases like compile, test, package, install, deploy.

• Maven build lifecycle consists of three main phases: clean, default, and site.

• Each phase consists of a series of goals that are executed in a specific order.

• Some common goals in Maven build lifecycle include compile, test, package, install, and deploy.

• The clean phase removes all files generated by the previous build.

• The default phase ...read more

Code to reverse a sentence using array of strings.

• Split the sentence into an array of words

• Reverse the array

• Join the array back into a sentence

Static block in Java is a block of code that is executed only once when the class is loaded.

• Static block is used to initialize static variables of a class.

• It is executed before the main method.

• Syntax: static { // code to be executed }

• Example: static { System.out.println("Static block executed"); }

Exclude and include in TestNG are used to specify which test methods to run or skip during test execution.

• Exclude attribute is used to specify which test methods to skip during test execution

• Include attribute is used to specify which test methods to run during test execution

• Both attributes can be used in the testng.xml file or in the @Test annotation

• Example: @Test(groups = {"smoke"}, excludeGroups = {"regression"})

To reverse a digit, convert it to a string and then reverse the string.

• Convert the digit to a string

• Use built-in functions to reverse the string

• Convert the reversed string back to a digit if needed

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.

• If a class...read more

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'

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

Project structure refers to the organization of files, folders, and resources within a software project.

• Main folders like src (source code), test (test cases), lib (libraries), docs (documentation)

• Subfolders for specific modules or components

• Configuration files like pom.xml, package.json, etc.

• Build scripts like Jenkinsfile, Dockerfile

• Version control files like .gitignore, .gitattributes

• README.md file for project overvi
