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.

Contract Acceptance Testing is performed to validate that the software developed aligns with the requirements specified in the contract between the client and the vendor. This ensures that client expectations and contractual obligations are met.

A bug that was previously fixed but reappears in later phases is typically assigned the status "Reopened." This indicates that the bug was once addressed but has resurfaced, requiring additional attention and potentially a more thorough fix.

As the number of automated test scripts in a suite grows, maintenance becomes more challenging. Any change in the application can result in a need to update many test scripts, making the process time-consuming. Additionally, as scripts grow, finding the cause of a failure can be like finding a needle in a haystack, leading to increased debugging time.

Interface testing is specifically designed to ensure that the interaction between different software applications occurs smoothly. It verifies that communication processes are functioning as expected when the software system interfaces with other software systems or hardware components. Performance and load testing focus on system's performance metrics, while security testing checks vulnerabilities.

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.

Passive Testing is a form of security testing where the tester observes the system but does not interact directly with it. Unlike penetration testing, which involves exploiting vulnerabilities, passive testing focuses on identifying potential vulnerabilities without attempting to exploit them.

Beta testing involves releasing the software product to a limited number of end-users for evaluation. This allows the development team to get real-world feedback from users and identify potential defects or areas of improvement before a public release.

Baseline Identification involves tagging or marking specific points in a development timeline. By identifying baselines, one can retrieve a specific version of software that was marked as significant, such as a release. In this case, the software version released six months ago would have been a baseline, allowing it to be easily retrieved for review.
