A technical review is a formal type of review that focuses on discussing, making decisions, evaluating alternatives, finding defects, solving technical problems, and checking conformance to specifications, plans, regulations, and standards. It is typically conducted by a team of experts and aims to ensure the technical quality of the product.

For a web-based service designed to be available 24/7, a comprehensive testing approach is necessary to ensure functionality, security, reliability, and performance. Functional testing at the system level will verify the security aspects. Load testing at the system level will ensure the system can handle expected loads and remain available. Regression testing across all levels will confirm that changes do not introduce new defects. Structure-based testing at the component level will ensure the internal structure of components is robust. The ISTQB syllabus outlines these testing types and their importance in different contexts and levels​​.

Test execution tools include tools that directly assist in the execution of tests and comparison of actual outcomes with predicted outcomes. A test harness (b) is used to execute tests by providing the necessary context and data inputs for running a test. Test comparators (d) are used to compare the actual results produced by the system under test with the expected results, which is a key part of test execution.

Based on the given flow graph and the test cases provided:

Test Case 1 covers the path P → Q → R → U.

Test Case 2 covers the path P → Q → S → V.

Test Case 3 covers the path P → Q → S → W → X.

Test Case 4 covers the path P → Q → S → W → Y.

All decision points (P, Q, R, S, W) are covered at least once, ensuring 100% decision coverage. However, not all statements (T) are covered, as there is no test case that covers the path leading to statement T.
