Focusing on high-priority test cases ensures that the most crucial functionalities are tested, reducing the risk of critical defects. While allocating more resources can be helpful, it might not always be feasible. Skipping testing altogether is not recommended due to high risks. Parallelizing tasks could help but prioritizing guarantees the most important areas are covered.

Black-box Testing, often called behavioral testing, focuses on examining the functionality of the application without delving into its internal structures or workings. The main goal is to test how the software behaves in response to various inputs and conditions.

"Test Cycle Time" includes the total time taken for one cycle of testing, from test planning to closure. During test estimation, considering the Test Cycle Time is crucial as it ensures that time is allocated not just for executing tests but also for reviewing and retesting, if necessary.

The traceability matrix is prepared during the Requirement Analysis phase of STLC. It's a document that maps and traces user requirements with test cases. It ensures that all requirements are covered by test cases so that no functionality is left untested.

"Exploratory Testing" is an unscripted testing approach where the tester actively controls the design of the tests as those tests are performed. The tester often follows their intuition and experience during testing.

Unit testing primarily focuses on testing individual units or components of a software in isolation. The main aim is to validate that each unit of the software performs as designed. It ensures that every part of the software behaves correctly in isolation.

Git is a widely-accepted distributed version control system used in modern software development processes. It allows multiple developers to work on the same project simultaneously, keeping track of code versions and changes. Jenkins is primarily a CI/CD tool, JIRA is more for issue tracking, and Selenium is for web testing.

A Test Architect typically takes the lead in deciding the testing methodology and tools within a test organization. Their knowledge of system architecture combined with testing expertise allows them to determine the most effective testing strategies and tools to ensure comprehensive coverage and efficiency.

In Configuration Management, a Baseline refers to a set standard or reference point in the development process. It's a specifically approved version of the software that can be used for further development, ensuring stability and a starting point for subsequent activities.

The decision on when to stop or continue testing is made during the Test Closure activity. This decision is based on factors like the testing deadline being reached, the achievement of a certain quality level, or the completion of all test cases. The Test Closure phase involves finalizing and reporting the results and evaluating the testing process.
