What is Software Testing?

Before a software product is made available to consumers, it must undergo software testing to be evaluated for flaws (errors or bugs) and fixed. Software testing can be carried out either manually or automatically. The process of developing software includes software testing as a crucial step. It aids in ensuring that the program is error-free and satisfies user requirements.

Software Testing Interview Questions with Answers for Freshers

Check out the most commonly asked software testing interview questions with answers for freshers.

Check out the most commonly asked software testing interview questions with answers for freshers

What is the primary goal of software testing?

The main objective of software testing is to find flaws and faults in the software. Testers ensure that the program is fully functional, satisfies all specifications, and provides a top-notch user experience by extensively testing it.

Which testing technique helps assess a software application’s functionality by observing how it behaves under different conditions?

“Black Box Testing” is a testing method that evaluates a software application’s functioning under various circumstances. Comprehensive testing is made possible without looking into the underlying workings of the program since testers are unaware of to the inside code and concentrate on expected inputs and outputs.

What is the purpose of Regression Testing?

Regression testing seeks to ensure that fresh modifications or upgrades to a software program don’t negatively impact its current functionality. Retesting the program is necessary to ensure that features that were previously functional are still there after new modifications have been made.

What is the difference between verification and validation in software testing?

While verification guarantees that the program satisfies the needs and expectations of the user, validation verifies that the software complies with specifications and standards. While validation concentrates on the functioning and usefulness of the finished product, verification concentrates on the development process.

Which testing level involves testing individual units or components of a software application in isolation?

To verify the accuracy and operation of a software application’s separate pieces or components, unit testing is used. It is often the initial testing phase of the development process.

Which testing type evaluates the software application’s performance in terms of responsiveness, speed, and stability under varying workloads?

A software application’s responsiveness, speed, and stability are assessed through performance testing under various workloads. It aids in the identification of performance bottlenecks, ensuring that the program can successfully meet user requests.

What is the key advantage of using Automated Testing over Manual Testing?

Compared to manual testing, automated testing provides quicker test execution, more test coverage, and higher accuracy. Continuous integration and delivery are made possible, and repeated tests’ time and effort requirements are reduced.

What is the role of a Test Case in software testing?

A test case is a collection of prerequisites, inputs, anticipated results, and post-conditions that spell out the procedures to be followed while testing software. It offers a methodical way to verify the accuracy of the software program.


When assessing a candidate’s expertise and knowledge in the field of software testing, MCQs are crucial. Aspiring software testers may improve their knowledge and shine in job interviews by knowing the most recent concepts and methods.

We recommend readers take the Firstnaukri Aptitude Test (FNAT), a great tool for polishing abilities and developing confidence in numerous interview aptitude tests, to continue their preparations for aptitude exams. Take advantage of the chances that arise as you grow in your profession as a software tester.
