A configuration management tool helps in maintaining and managing changes to software, including test cases. It ensures that changes are tracked and can be retrieved if needed. In this scenario, using a configuration management tool would have allowed Sam's updates to be stored in a central repository, preventing the loss of his work even if his PC's hard disk crashed.

ISTQB CTFL Syllabus V4.0, Section 5.4 on configuration management, which describes the role of configuration management tools in maintaining control over changes​​.

The problem described involves a software implementation error in a decision statement for calculating a bonus based on the Total Amount of Sales (TAS). The requirement states that if TAS is 300,000€ or more, a bonus should be paid. However, the software incorrectly implements this with "IF (TAS = 300000)" instead of "IF (TAS >= 300000)".

Applying Boundary Value Analysis (BVA) to this situation involves selecting test cases at the boundaries of the input domain, including just below, at, and just above the boundary conditions.

Test Case TC1 = 299999:

This value is just below the boundary (300,000).

Expected Result: No bonus should be paid.

Actual Result: No bonus paid.

TC1 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (no bonus).

Test Case TC2 = 300000:

This value is exactly at the boundary.

Expected Result: Bonus should be paid.

Actual Result: Bonus paid.

TC2 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (bonus paid).

Test Case TC3 = 300001:

This value is just above the boundary.

Expected Result: Bonus should be paid.

Actual Result: No bonus paid due to the incorrect implementation.

TC3 highlights the fault because the implemented condition "IF (TAS = 300000)" fails to pay the bonus, whereas the correct condition "IF (TAS >= 300000)" would pay the bonus.

BVA focuses on the edges of input ranges where errors are more likely.

The critical values are just below, at, and just above the boundary.

Boundary Value Analysis (BVA):Verification:According to the ISTQB CTFL syllabus, BVA is an essential technique for identifying potential errors at the boundaries of input ranges. This is because developers are more likely to make mistakes at these extremes​​.

Therefore, TC3 (300001) is the test case that would highlight the fault in the software's implementation of the decision condition.

This answer is correct because product risks are risks that affect the quality of the software product, such as defects, failures, or non-compliance with requirements or standards. Project risks are risks that affect the project’s schedule, budget, resources, or scope, such as delays, cost overruns, skill gaps, or scope changes. In this case, [I] and [IV] are product risks, as they relate to the accessibility and security of the software product, which are quality attributes. [II] and [III] are project risks, as they relate to the delivery time and the test automation skills of the test team, which are project factors. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.1.1.1

This answer is correct because identifying potential anomalies in the work product under review is one of the tasks the Author is responsible for, as part of a typical formal review. The Author is the person who creates the work product to be reviewed, such as a requirement specification, a design document, or a test case. The Author’s tasks include preparing the work product for the review, identifying potential anomalies in the work product, and fixing the anomalies found in the work product after the review. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.4.2.1

To determine the correct execution order that minimizes the number of configuration switches and respects the dependencies, we need to consider the following:

Initial Configuration: CONF1.

Dependencies:

TC1 depends on nothing.

TC2 depends on TC4.

TC3 depends on TC4.

TC4 depends on nothing.

TC5 depends on TC1.

Configuration Requirements:

TC1 requires CONF2.

TC2 requires CONF2.

TC3 requires CONF1.

TC4 requires CONF1.

TC5 requires CONF2.

Given the initial configuration is CONF1, start with test cases that can run on CONF1 and respect the dependencies. Then switch to CONF2 only when necessary. The optimal order to minimize configuration switches is:

Start with TC4 (no dependencies, CONF1).

Continue with TC3 (depends on TC4, CONF1).

Switch to CONF2.

Execute TC2 (depends on TC4, CONF2).

Continue with TC1 (no dependencies, CONF2).

Finally, execute TC5 (depends on TC1, CONF2).

Therefore, the correct order is:

TC4 (CONF1)

TC3 (CONF1)

TC2 (CONF2)

TC1 (CONF2)

TC5 (CONF2)

Thus, the answer is A. TC4, TC3, TC2, TC1, TC5.
