Equivalence Partitioning is a test design technique where input data is divided into different equivalence classes based on their behavior. Testing only one value from each class is deemed sufficient. For a vast range of input numbers, it reduces the number of tests while ensuring effective coverage.

Component Testing: Also known as module or unit testing, this focuses on testing specific functions or modules of an application independently to ensure their performance. It aims to identify any issues at the component level before integrating them into the larger system.

The "Retesting" phase in the bug life cycle is when a specific defect or bug has been fixed and is tested to ensure its rectification. It's a verification process to confirm that the particular defect has been successfully addressed.

Incremental Integration testing involves testing parts of a system sequentially as they're developed. In environments where multiple teams work on different components, this approach ensures that each new piece integrates smoothly with the existing parts, helping detect issues early and reducing integration risks.

A Walkthrough is a type of review where the author leads members of the review through the document based on their understanding. It's informal in nature and often relies on scenarios to provide the reviewers with a deeper understanding. The main goal is to gather feedback and achieve a common understanding.

Configuration Auditing is a critical aspect of Configuration Management. It involves the process of evaluating and examining the configurations to ensure that they align with the approved configuration documentation. Through this, unauthorized changes, discrepancies, or inconsistencies can be detected and addressed promptly.

Requirement-based Testing, as the name implies, involves designing test cases directly based on the system requirements. It ensures that the software system meets and conforms to the specified requirements, making certain that all functionalities are tested as intended.

If a defect is considered not genuine or if it's not a real issue, it is typically marked as "Rejected." This status indicates that the defect raised is either not replicable, is intended behavior, or isn't valid in the context it was reported.

Beta Testing is one of the final stages in the software testing process where the software is released to a limited number of end-users under real-world conditions. The primary purpose is to get feedback from users, ensuring that there are no major failures when it's released to the public and to understand any enhancements users might like to see.

Parallel execution refers to running multiple test cases or test suites concurrently, usually distributed across various machines or cores. This drastically reduces the total testing time, especially in large-scale projects, as it eliminates the need to wait for each test to finish.
