Mphasis Automation Test Engineer Interview Questions and Answers

A constructor is a special type of method in a class that is automatically called when an object of that class is created.

• Constructors have the same name as the class they belong to

• They are used to initialize the object's state or perform any necessary setup

• Constructors can have parameters to customize the initialization process

• Example: public class Car { public Car(String color) { this.color = color; } }

Yes, a static method can be overridden in Java using the concept of method hiding.

• In Java, static methods cannot be overridden in the traditional sense like instance methods.

• When a subclass defines a static method with the same signature as a static method in the superclass, it is called method hiding.

• Method hiding does not follow polymorphism and is resolved at compile time based on the reference type.

• Example: class...read more

Yes, a static local variable can be created inside a static method.

• Yes, a static local variable can be declared inside a static method in programming languages like C++.

• Static local variables retain their values between function calls.

• Example: static void myStaticMethod() { static int count = 0; count++; }

String memory allocation is dynamic and depends on the length of the string.

• String memory allocation is dynamic and can change based on the length of the string.

• In Java, a String object is stored in the heap memory.

• Each character in a String typically takes up 2 bytes of memory.

• String objects in Java are immutable, meaning once a String object is created, it cannot be changed.

Yes, you can create a static method inside an abstract class or interface.

• Static methods can be defined in interfaces since Java 8.

• Static methods in interfaces are used for providing utility methods that are not tied to any specific instance of the interface.

• Static methods in abstract classes can be used for common functionality that does not require an instance of the class.

The parent class of Java is the Object class.

• All classes in Java are directly or indirectly derived from the Object class.

• The Object class is the root class in Java's class hierarchy.

• It provides methods that are common to all objects in Java, such as toString(), equals(), and hashCode().

Window Handles in Selenium are unique identifiers used to handle multiple browser windows in a Selenium test script.

• Window Handles are unique alphanumeric strings assigned to each browser window opened by Selenium.

• They are used to switch between different browser windows during a test script execution.

• Window Handles can be obtained using getWindowHandles() method in Selenium.

• Example: Set<String> handles = driver....read more

A framework is a set of guidelines, tools, and libraries used to develop and maintain software applications.

Use two variables to keep track of the largest and second largest numbers in the array.

• Iterate through the array and compare each element with the largest and second largest variables.

• Update the variables accordingly to find the second largest number.

• Return the second largest number once the iteration is complete.

The xpath of a product on Amazon can be found by inspecting the HTML code of the product page.

• Right click on the product on Amazon and select 'Inspect' to view the HTML code

• Locate the unique identifier of the product, such as class name or id

• Construct the xpath using the unique identifier and other relevant attributes

Object-oriented programming concept in Java

• Encapsulation: bundling data and methods that operate on the data

• Inheritance: creating new classes using existing classes

• Polymorphism: ability to present the same interface for different data types

Velocity in Agile Scrum measures the amount of work completed in a sprint, guiding future planning and forecasting.

• Velocity is calculated by summing the story points of completed user stories in a sprint.

• For example, if a team completes 30 story points in one sprint, their velocity is 30.

• Velocity helps teams estimate how much work they can take on in future sprints.

• It can vary from sprint to sprint due to team dynamics...read more

OOP (Object-Oriented Programming) is a programming paradigm based on objects that encapsulate data and behavior.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the same interface for diffe...read more
