Q6: What are the different types of Software Testing?
There are several types of software testing, each serving a specific purpose. The main types include:
Functional Testing : Validates that the software performs its intended functions correctly.
Non-Functional Testing : Evaluates the non-functional aspects of the software, such as performance, usability, and reliability.
Other Testing Types:
Q7: What is the difference between Verification and Validation?
Verification : The process of evaluating work products (such as requirements, design, code, etc.) to ensure they meet the specified requirements and standards. It answers the question, "Are we building the product right?"
Validation : The process of evaluating the final software product to ensure it meets the business needs and requirements. It answers the question, "Are we building the right product?"
Key Differences:
Q8: What is a Defect Life Cycle?
The Defect Life Cycle, also known as the Bug Life Cycle, is the process a defect goes through from its identification to its closure. The stages typically include:
Q9: What is a Test Plan, and what are its key components?
A Test Plan is a document that outlines the scope, approach, resources, and schedule for testing activities. It serves as a guide for the testing process and ensures that all aspects of the project are covered.
Key Components of a Test Plan:
Q10: What are Test Scripts, and how do they differ from Test Cases?
Test Scripts : Detailed instructions for automated tests that include the exact steps to be executed by an automation tool. They are typically written in programming or scripting languages and are used for repetitive tasks.
Test Cases : High-level descriptions of test scenarios that outline the conditions, inputs, and expected results for a specific test. They are written in plain language and can be executed manually or automated.

Q11: What is Boundary Value Analysis in software testing?
Boundary Value Analysis (BVA) is a black-box testing technique used to identify errors at the boundaries of input domains rather than within the range. This technique focuses on testing the values at the edges of equivalence classes.
Key Points:
Q12: What is a Traceability Matrix in software testing?
A Traceability Matrix is a document that maps and traces user requirements with the test cases designed to verify those requirements. It ensures that all requirements are covered by test cases.

Q13: What is the difference between Alpha Testing and Beta Testing?
Alpha Testing :
Beta Testing :
Q14: What are the key principles of Software Testing?
There are seven key principles of Software Testing:
Q15: What is Exploratory Testing, and when is it used?
Exploratory Testing is an informal testing approach where testers actively explore the application without predefined test cases. It relies on the tester's creativity, intuition, and experience to find defects.

Q16: What is Regression Testing, and why is it important?
Regression Testing is a type of software testing that ensures that recent code changes have not adversely affected the existing functionality of the software. It involves re-running previously completed tests on new code changes to verify that the software continues to perform as expected.
Importance of Regression Testing:
Q17: What is Usability Testing, and what are its key aspects?
Usability Testing is a non-functional testing technique used to evaluate how easy and user-friendly a software application is. It focuses on the end-user experience and aims to identify usability issues that could impact the user’s interaction with the application.
Key Aspects of Usability Testing:
Methods:
Q18: What is the difference between Static Testing and Dynamic Testing?
Static Testing :
Dynamic Testing :
Key Differences:
Q19: What is the role of a Test Manager in software testing?
A Test Manager is responsible for overseeing the testing process, ensuring that testing activities are effectively planned, executed, and managed. The Test Manager plays a crucial role in delivering a high-quality software product.
Key Responsibilities:
Q20: What is Performance Testing, and what are its different types?
Performance Testing is a non-functional testing technique used to determine how a software application performs under various conditions. It assesses the speed, responsiveness, and stability of the software.
