Effort estimate does not depend on the budget of the project, but rather on the scope, complexity, and quality of the software product and the testing activities1. Budget is a constraint that may affect the feasibility and accuracy of the effort estimate, but it is not a factor that determines the effort estimate. Effort estimate is the amount of work required to complete the testing activities, measured in terms of person-hours, person-days, or person-months2.

The other options are correct because:

A. Once the test effort is estimated, resources can be identified and a schedule can be drawn up, as they are interrelated aspects of the test planning process3. Resources are the people, tools, equipment, and facilities needed to perform the testing activities4. Schedule is the time frame and sequence of the testing activities, aligned with the project milestones and deadlines5.

B. Effort estimate can be inaccurate because the quality of the product under tests is not known, as it affects the number and severity of the defects that may be found and the rework that may be needed to fix them6. Quality is the degree to which the software product satisfies the specified requirements and meets the needs and expectations of the users and clients7.

D. Experience based estimation is one of the estimation techniques, which relies on the judgment and expertise of the testers and other project stakeholders to estimate the test effort based on similar projects or tasks done in the past. Experience based estimation can be useful when there is a lack of historical data, formal methods, or detailed information about the software product and the testing activities.

When deciding on the order of test execution based on priorities and dependencies, the correct sequence should consider both the priority levels and any dependencies between test cases. Here’s the analysis:

Test B has the highest priority (1) and depends on Test D.

Test D should be executed before Test B.

Test C has a medium priority (2) and depends on Test A.

Test A can be executed at any time since it has no dependencies.

Considering these dependencies and priorities, Test D should be executed first, followed by Test B. After that, Test A and finally Test C. Therefore, the correct sequence is D-B-A-C??.

In Agile estimation sessions, particularly during Planning Poker, the goal is to reach a consensus on the effort required for a user story. The process encourages discussion and collaboration among team members to understand the story's requirements and complexities fully. Here’s a breakdown of the options and why D is the correct choice:

Option A: Calculating the arithmetic mean of all estimates.

This method is straightforward but does not facilitate team discussion or consensus-building. It merely averages out the estimates without addressing the reasons behind the varying estimates. Thus, important insights and understanding of the task complexity might be missed.

Option B: Selecting the most frequent estimate value.

While this approach acknowledges the majority’s opinion, it ignores the minority views, which might highlight significant aspects of the story that need consideration. It doesn't ensure that all perspectives are considered and discussed.

Option C: Calculating the mean of the most optimistic and pessimistic estimates.

This approach considers the extremes but again lacks the team discussion and consensus aspect. It also assumes that the extreme values alone can balance out the estimate, which might not always capture the true complexity or simplicity of the task.

Option D: Discussing the most pessimistic and optimistic estimates.

This approach fosters team collaboration and understanding. Memb4 and Memb6 explain their reasoning for the highest and lowest estimates, respectively, which can reveal different perspectives on the task's complexity. This discussion helps the team align their understanding and often leads to a more accurate and agreed-upon estimate in subsequent rounds.

In conclusion, the main goal of Agile estimation techniques like Planning Poker is to encourage team communication and collaboration to ensure that all aspects of the user story are considered. Option D best aligns with this goal by promoting discussion and consensus.

During the review planning phase of a formal review process, decisions are made regarding which standards and procedures will be followed. This planning ensures that the review process is structured, consistent, and aligned with organizational or project-specific guidelines, thereby enhancing the effectiveness and reliability of the review outcomes.

The tool described in the question supports the automated creation and installation of builds and the execution of various types of automated tests. This aligns with the practices and tools typically found in DevOps environments, which aim to integrate and automate the processes between software development and IT teams. DevOps tools facilitate continuous integration (CI) and continuous delivery (CD), enabling automated building, testing, and deployment of applications. Therefore, the correct answer is that this is an example of DevOps related tools??.
