Listed below are ten commonly asked interview questions on the topic "Introduction to Software Testing":
Ans: The process of testing a software application or system to find defects and bugs and ensure that it meets the specified requirements is called Software Testing.
Ans: Software Testing is crucial because it helps in identifying and fixing defects early in the development process, improving the quality and reliability of the software, enhancing customer satisfaction, and reducing overall costs.
Ans: The different types of Software Testing are Functional Testing, Non-functional Testing like System Testing, Integration Testing, Acceptance Testing, and Regression Testing.
Ans: Verification evaluates work products like documents, design specifications, and code to ensure they meet the specified requirements. Conversely, Validation focuses on assessing the final software product to ensure that it satisfies the user's needs.
Ans: Smoke testing is performed to ensure that the critical functionalities of the software work correctly before proceeding with detailed testing. Sanity testing is a narrow, focused testing effort to check if recent changes or fixes have not introduced any new issues.
Ans: Black box testing focuses on testing the software's functionality without considering its internal structure or implementation details. It is known as glass box or structural testing, White box testing involves testing the software's internal structure, design, and code.
Ans: Regression testing is the process of retesting the modified or updated parts of the software to make sure that the changes have not introduced any new defects and that the existing functionalities still work as expected.
Ans: Retesting involves executing the failed test cases again to verify if the defects have been fixed. In contrast, Regression Testing is performed to ensure that the modifications or new additions to the software have not caused any unintended side effects in previously working areas.
Ans: Manual testing involves executing test cases manually without using automation tools, relying on human observation and judgment. Automation testing, on the other hand, involves using automation tools to run test cases, validate results, and compare expected and actual outcomes.
Ans: A test case can be defined as a set of conditions, inputs, actions, and expected results developed to verify specific functionalities or aspects of the software. It serves as documentation that guides the tester in performing a particular test.
Ans: In most testing methods, testers follow an established testing plan to help find bugs and errors. However, in the Exploratory Testing method, testers evaluate an application randomly, like an explorer, without implementing a testing plan. This is particularly helpful in identifying bugs that were previously missing on other testing methods. It’s like solving a maze and can be quite fun. Any errors detected by them will be noted down for changes.
Ans: In this testing method, the testers test an application completely from the start to the finish. It covers all the possible flow to find out whether there are any discrepancies and if the right input is passed between the software application and the systems.
Ans: The test report is a document that consists of everything from the testing objectives to the final results. Consider it like the progress report that contains all the details of the testing, which helps in evaluating whether a product is ready for deployment or not. It also helps testers find the status of the project as well as its quality. Other than that, it helps testers take corrective measures since it contains information on product defects as well.
Ans: A test suite is a set of test cases developed to evaluate a software’s performance and functionalities. It can be used to test specific features of an application and can be grouped accordingly. This helps the testers to find out which tests should be performed as a priority and which tests can be performed later. By doing so, testers can test the critical features of software first, as well as reduce defects during testing.
Ans: A/B Testing is one of the most popular Software Testing methods. It involves testing at least two or more versions of the same application with different features with various users. For example, one group of users will be given a version which we can call Part A, and the other group will be given a different version, which we can call Part B. Hence, the naming A/B testing is a risk-free method of testing. The testers will then collect feedback from both sets of users to find out where their design performs well and where it lacks.

d) Test execution: Running the test cases, recording results, and reporting defects.
e) Defect tracking and management: Logging, prioritising, and tracking defects until resolution.
f) Test closure: Analysing test coverage, generating reports, and documenting lessons learned.
Ans: Positive testing focuses on validating that the software behaves as expected when given valid inputs. Negative testing, however, aims to test the software's ability to handle invalid or unexpected inputs and conditions, such as error messages or boundary cases.
Ans: Boundary testing is a technique used to validate the behaviour of the software at its boundaries or limits. It involves testing values at the extreme ends of the input domain, including minimum, maximum, and edge values, to ensure that the software handles them correctly.
Ans: Exploratory testing is a dynamic testing approach where the tester explores the software's functionalities, features, and user interfaces without following predetermined test scripts. It allows the tester to investigate and identify defects by using their domain knowledge, intuition, and experience.
Ans: Regression testing is the process of retesting the modified or impacted parts of the software to ensure that the changes or fixes have not introduced new defects or caused unintended side effects in previously working areas.
Ans: Defect prioritisation is based on factors like severity, impact on business, frequency of occurrence, and customer requirements. High-severity defects that directly impact critical functionalities or pose risks to users are given the highest priority, followed by medium and low-severity defects.
Ans: Test coverage can be ensured in manual testing by mapping test cases to the requirements, identifying test scenarios that cover different functionalities, employing techniques like boundary value analysis, comparison testing, equivalence partitioning, and maintaining a traceability matrix to track the coverage of requirements by test cases.

It enables the team to continuously integrate and test code changes, detect defects early, and provide rapid feedback for faster iterations. Test automation also helps achieve higher test coverage and facilitates regression testing.
Ans: Agile testing embraces changing requirements through close collaboration between the development team, business stakeholders, and testers. Testers actively participate in refinement sessions, sprint planning, and daily stand-ups to ensure that requirements are well understood and can be adapted quickly. Agile testing also employs techniques like exploratory testing to accommodate changing conditions during the sprint.
