Updated: Aug 12, 2021


Welcome to the compilation of important manual testing interview questions.


Please consider the following note from the author -

  • Our aim is not only to give direct answers but also to make readers understand the basic and important concept of software testing, hence they can counter any questions asked during interviews.

  • In case any reader has any other questions, do leave a comment and we will try to explain the concept. :)



Following are important manual testing interview questions -


1. What is software testing?

Software testing is a planned activity to ensure the quality of the software and it is bud-free before it delivers to the end-user. When the software is in the developing phase, the goal of testing is to identify the bugs, errors, and anomalies that are introduced in the code and stop them from reaching the end-user.


2. Why software testing is required? or Role of testing in business?

A failure in software could cause severe consequences such as financial loss, customer and reputation loss, or even loss of life. With software now being used in every sector and industry, be it in advanced medical treatments like robotic neurosurgery or surgical implements, a failure in the software or a minor glitch can cause catastrophic implications. Software that is used in online payments, investment banking, government systems that hold confidential data, needs to work bug-free to avoid any such events.


Benefits of software testing

  1. Quality of product- The most important function of software testing is delivering a quality product. A cheap quality product will never win customers or add value to the business.

  2. Cost-effectiveness- Earlier the bug you fix, the more the cost business will save. Fixing a defect early in the lifecycle of software costs a fraction when compared to fix the defect in production. There is an exponential increase in the cost to fix a bug as we move right in the software development life cycle. As per the estimates, it will cost you 30x more to fix a defect in the product than to fix the requirement or design level.

  3. To achieve competitive advantage - Now in the information age, where software is the defining growth of the economy, and testing has become a significant part of the Software Development Life Cycle (SDLC). The software has to be tested for faults and discrepancies to ensure the desired outcome, quality product, and satisfactory user experience in turn allowing companies to have a competitive advantage over rivals.


3. What are the types of testing?

Broadly software testing can be classified as -

  1. Black box testing

  2. White-box testing

  3. Grey-box testing


4. What are the levels in software testing?

  1. Unit Testing

  2. Integration Testing

  3. System Integration Testing (SIT)

  4. User Acceptance Testing (UAT)
