The whole team approach, often advocated in Agile methodologies, emphasizes collaboration and collective responsibility among all team members. This approach enhances the relationships within the team and improves overall collaboration, which in turn benefits the project's success. According to the ISTQB CTFL Syllabus v4.0, the whole team approach fosters better communication and cooperation, leading to more effective problem-solving and higher-quality outcomes​​.

The features of the test object to be tested and those excluded from the testing represent information that is usually included in a test plan and, in the given test plan, it is more likely to be specified within “Test Scope” rather than in the other two sections mentioned. The test scope defines the boundaries and limitations of the testing activities, such as the test items, the features to be tested, the features not to be tested, the test objectives, the test environment, the test resources, the test assumptions, the test risks, etc. The test scope helps to establish a common understanding of what is included and excluded from the testing, and to avoid ambiguity, confusion, or misunderstanding among the stakeholders. The other two sections, “Testing Communication” and “Stakeholders”, are also important parts of a test plan, but they do not directly address the features of the test object. The testing communication describes the methods, frequency, and responsibilities for the communication and reporting of the testing progress, status, issues, and results. The stakeholders identify the roles and responsibilities of the people involved in or affected by the testing activities, such as the test manager, the test team, the project manager, the developers, the customers, the users, etc. References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

Involving testers only during the testing phase is incorrect as per the ISTQB CTFL syllabus. Effective involvement of testers is crucial throughout the entire software development lifecycle (SDLC). This includes early stages such as requirement analysis and design, which allows testers to understand the design decisions and detect defects early. Early involvement helps in better understanding the project and ensures that quality is built into the product from the beginning. Furthermore, the ISTQB syllabus emphasizes the importance of testers contributing to all activities in the SDLC, including design discussions, to enhance defect detection and prevention.

Comprehensive and Detailed In-Depth Explanation:Theratio-based estimation methodrelies on historical relationships betweendevelopment and testing effort.

Using the given5:3 ratio:

Thus, the correct answer is270 person-days (D).

(A) and (C) are incorrectas they overestimate the effort.

(B) underestimates the testing effort based on the ratio.

Ratio-based estimationhelps allocate resources effectively based on past project data.

The correct test execution sequence should consider both the dependencies between the requirements and their priorities. According to the diagram, the sequence begins with R2 (P1) as it is a prerequisite for R3 (P4). Then R1 (P3) can be tested. R3 follows as it depends on R2. Next, R7 (P4) should be tested before R6 (P3) and R5 (P2), as indicated by their dependencies. Finally, R4 (P1) and R8 (P1) can be tested. Therefore, the best sequence is R2, R1, R3, R7, R6, R5, R4, R8.Reference:ISTQB CTFL Syllabus V4.0, Section 5.1.5

Good testing practice dictates that each test level (e.g., unit testing, integration testing, system testing) should have distinct test objectives aligned with the phase of the software development lifecycle it addresses. This ensures that testing is effective and relevant at each stage. According to the ISTQB CTFL Syllabus v4.0, establishing clear test objectives that are consistent with the development phase helps in achieving specific goals and improving the overall quality of the software product​​.
