10+ Kamaraj College of Engineering & Technology Interview Questions and Answers

I will use a combination of regression testing, exploratory testing, and risk-based testing to ensure comprehensive coverage.

• Perform regression testing on critical functionalities to ensure they still work as expected

• Conduct exploratory testing to uncover any unforeseen issues or bugs

• Prioritize testing based on risk assessment to focus on high-impact areas first

• Use automation testing tools for repetitive tasks to save time and effort

Implemented App automation using Selenium WebDriver and Appium for regression testing and continuous integration.

• Used Selenium WebDriver for web application automation

• Utilized Appium for mobile application automation

• Implemented automation scripts for regression testing

• Integrated automation tests into continuous integration pipelines

Program that prints 1 if user inputs 0, and 0 if user inputs 1.

• Create a function that takes user input as parameter

• Check if input is 0, then print 1. If input is 1, print 0

• Handle invalid inputs if necessary

Program to find second lowest number without using collection and nested loop.

• Sort the array in ascending order

• Check for duplicates and skip them

• Return the second element in the sorted array

Re-testing is testing the same functionality again to ensure the defect has been fixed, while regression testing is testing the unchanged parts of the software to ensure no new defects have been introduced.

• Re-testing focuses on the specific defect that was fixed, while regression testing focuses on ensuring that the rest of the software still works as expected.

• Re-testing is done after a defect is fixed, while regression testing is done after new code changes are made.

Event loop is a mechanism in JavaScript that allows asynchronous code to be executed.

• Event loop continuously checks the call stack and the task queue.

• If the call stack is empty, it takes the first task from the queue and pushes it to the call stack.

• Event loop is responsible for handling asynchronous operations in JavaScript.

• setTimeout, setInterval, and AJAX requests are examples of asynchronous operations that use event loop.

High priority and low severity bug example

• Incorrect logo displayed on login page

• Spelling mistake in error message

• Alignment issue in the footer of the website

Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their scope.

• Hoisting applies to variable and function declarations, not initializations

• Variables declared with let and const are not hoisted

• Function declarations are hoisted before variable declarations

• Function expressions are not hoisted

var is function scoped, let and const are block scoped.

• var can be redeclared and updated within its scope

• let can be updated but not redeclared within its scope

• const cannot be updated or redeclared once declared

• let and const are not hoisted like var

• const must be initialized during declaration

Middlewares are software components that act as a bridge between different applications or systems.

• Middlewares are used to handle common functionalities like authentication, logging, and error handling.

• They can be implemented as a standalone software or as a part of a larger application.

• Examples of middlewares include Express.js middleware, Django middleware, and ASP.NET middleware.

A VPC endpoint is a virtual device within a VPC that enables private connectivity to AWS services without requiring an internet gateway or NAT device.

• VPC endpoints allow communication between instances in your VPC and AWS services without leaving the Amazon network.

• There are two types of VPC endpoints: Interface Endpoints and Gateway Endpoints.

• Interface Endpoints are elastic network interfaces with private IP addresses that serve as an entry point for traffic destined to a su...read more
