To determine the optimal test execution schedule that minimizes the number of configuration switches and respects the dependencies, we start with the initial configuration, CONF1.

TC4: It has no dependencies and runs on CONF1 (initial configuration).

TC3: Depends on TC4 and runs on CONF1. Since TC4 is already executed, we can proceed with TC3.

TC2: Depends on TC4 and runs on CONF2. We switch to CONF2 after TC3.

TC1: No dependencies and runs on CONF2. Since we are already in CONF2, we can execute TC1 next.

TC5: Depends on TC1 and runs on CONF2. Since TC1 is already executed, we can proceed with TC5 without additional configuration switches.

By following this sequence (TC4, TC3, TC2, TC1, TC5), we respect the dependencies and minimize the number of configuration switches

Comprehensive and Detailed In-Depth Explanation:

The primary objectives of testing, as outlined in the ISTQB CTFL v4.0 syllabus, include verifying whether specified requirements are met (A), detecting failures and defects (B), and validating that the test object functions as expected (D). However, "finding errors" (C) is not a direct objective. Errors result from human mistakes, but testing primarily identifies defects, which are flaws in the system that cause failures. Testing aims to reveal defects rather than directly identify errors in the code.

Comprehensive and Detailed In-Depth Explanation:

Acceptance criteria 8 states that the system should charge the user on the first business day of the following month. However, the test cycle only verified monthly payments for over a year, without confirming whether payments were processed specifically on the first business day.

(B) is incorrect because the test validated monthly and annual payment options.

(C) is incorrect because not all criteria were fully validated.

(D) is incorrect because OTP verification (6) was tested as part of registration.

Ensuring timely execution of payments (Criteria 8) requires additional validation.

Checklist-based testing is a technique where testers use pre-determined checklists to ensure that important aspects of a work product are evaluated. Over time, these checklists should be reviewed and updated periodically to maintain their effectiveness in detecting defects. As systems evolve, outdated checklists may miss new types of defects, thus diminishing their usefulness. Therefore, statement D is true according to the ISTQB CTFL syllabus​​.
