An inspection is a formal type of review wherein the process is structured and predetermined. The reviewers are chosen for their specific expertise and are required to go through the material thoroughly. It's more formal than other types of reviews like walkthroughs.

Gray Box Testing is an advanced testing method where the tester has partial knowledge of an application's internal workings. The tester understands the application's functionality but doesn't delve deep into its internal structures, making it a blend of black and white-box testing.

GUI (Graphical User Interface) Testing primarily focuses on the visual aspects of an application, ensuring that the colors, fonts, images, and other UI elements are presented correctly and provide a positive and consistent user experience. This helps in making the application visually appealing and user-friendly.

Selenium provides a tool named WebDriver, which allows testers to write scripts that can automate browser interactions. WebDriver provides a simple API to interact with browsers, making it easier for testers to create automation scripts for web applications without having to know intricate browser details.

Functional testing aims to validate the app's features by ensuring they function according to specified requirements. It verifies each function of the software application by feeding them input and examining the output.

Disabling the service is the immediate action to consider when an unauthorized service is running on an open port. This will prevent potential exploitation while the situation is further assessed. Running a malware scan is important, but the immediate threat is mitigated by stopping the service.

Cyclomatic complexity, introduced by Thomas McCabe, quantifies the complexity of a program by calculating the number of linearly independent paths through the source code. A higher cyclomatic value indicates a complex program with many branches, which may require more extensive testing to ensure each path is evaluated. It aids testers in assessing risks associated with the intricate logic of the code.

The "Assigned" bug status signifies that the bug has been assigned to a developer and is currently being addressed. "Open" means the bug has been recognized but might not be attended to yet. "Closed" denotes that the bug has been resolved. "Verified" signifies that the tester has verified the fix.

While automated tests can efficiently handle repetitive tasks, manual testing is indispensable for exploratory testing (where testers actively explore the application to identify issues) and usability checks to ensure a user-friendly experience.

Usability Testing not only evaluates the ease of use of a product but also examines its overall user interface, ensuring there's consistency in design, clear error messaging, and providing meaningful feedback. This ensures a seamless, user-friendly experience for the end-user.

Beta Testing is a phase where the software is exposed to the real-world potential users before the final release. It's a type of User Acceptance Testing (UAT) where actual users use the software and provide direct feedback. This feedback can be related to functionality, usability, performance, or any other aspect of the software.

QTP stands for QuickTest Professional. However, it was later rebranded by Hewlett-Packard (HP) as "Unified Functional Testing" (UFT). UFT provides a comprehensive solution for functional and regression testing and is one of the most popular tools in the testing industry for automating GUI testing tasks.
