Code execution is a dynamic activity where the software is run to check its behavior, whereas reviews are a static technique. Reviews focus on inspecting the product, gathering feedback, and identifying discrepancies without actually running the software.

Setting up automated tests requires a significant initial investment in terms of time, effort, and resources. This includes selecting the right tools, writing the scripts, and maintaining them to adapt to changes in the application being tested.

UI (User Interface) Testing primarily deals with the testing of the visual elements, layouts, and interactive parts of an application. The main goal is to ensure that users have a seamless and consistent visual experience across different functionalities, and that all interactive elements respond as expected.

Network Transition testing focuses on verifying the app's performance and behavior when transitioning between different network conditions, such as moving from WiFi to 4G or experiencing signal drops. It ensures the app remains stable and functional during such changes.

Manual Testing is primarily executed without the intervention of any testing tools. In manual testing, testers execute test cases without using any automation tools. They follow the test steps, input the defined set of data, and compare the actual results with the expected ones, relying solely on human efforts.

Unit Testing is the process of verifying individual units or components of a software. Since a sorting algorithm is a singular function or component, unit tests are essential to ensure that it works correctly in isolation. This ensures that the algorithm correctly sorts data under various scenarios before it's integrated with other components.

A/B Testing allows companies to compare two versions of an application (or specific features) to determine which one is more effective in engaging users. By using this method, the company can test new designs or elements to see if they address user feedback about the application being dull or non-engaging.

Integration testing focuses on combining units or components of a software and testing them as a group. It's about validating the interactions between different modules or services in a specified flow to ensure they work together as intended in the system's broader environment. Unit testing, on the other hand, checks individual components, while system testing validates the entire application.

The primary goal of test planning in the software testing lifecycle is to set the direction and scope for the testing activities. It helps in defining objectives, strategies, and the effort required to validate that the software meets its requirements and is free from critical issues.

Tool Assessment is the process wherein different test automation tools are critically evaluated and compared based on criteria like functionality, ease of use, and cost, among others. The aim is to choose the tool that aligns best with the project requirements, ensuring efficient and effective automation.
