Test case is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements. Test plan is a document outlining the scope, approach, resources, and schedule of testing activities. Test scenarios are detailed descriptions of possible interactions with the system.

• Test case: specific conditions to be tested, expected results, steps to execute

• Test plan: overall strate...read more

Hooks in Java are methods that allow subclasses to override or extend the behavior of a superclass.

• Hooks are commonly used in frameworks like JUnit and TestNG for test automation.

• They are often used for setup and teardown operations before and after test methods.

• Examples include @Before, @After, @BeforeClass, and @AfterClass annotations in JUnit.

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

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

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

Java OOPs concepts are used in automation framework design for better code organization and reusability.

• Encapsulation: Used to hide the internal implementation details of classes and provide access through methods.

• Inheritance: Allows for code reuse by creating parent-child relationships between classes.

• Polymorphism: Enables methods to behave differently based on the object they are called on.

• Abstraction: Helps in defin...read more

OTP can be handled by generating, sending, and verifying it in automated tests.

• Generate OTP using a random number generator

• Send OTP to the user via email, SMS, or any other communication channel

• Verify OTP entered by the user against the generated OTP

• Alternatively, use TouchAction class in Selenium for swipe action

• Specify the start and end coordinates for the swipe action

• Adjust the duration and speed of the swipe as needed

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
