The following diagram displays the logical dependencies between requirements and the individual requirement priorities. For example, 'R2->R3' means that R3 is dependent on R2. Priority is indicated by the number next to the letter ''P' i.e. P1 has a higher priority than P2. Which one of the following options best describes the test execution sequence using both requirement dependency and priority
A financial institution is to implement a system that calculates the interest rates paid on investment accounts based on the sum invested. You are responsible for testing the system and decide to use equivalence partitioning and boundary value analysis to design test cases. The requirements describe the following expectations: Investment range | Interest rate R500 to RIO 000 10% RIO 001 to R50 000 11% R50 001 to RlOOOOO 12% RIOOOOl to R500 000 | 13% What is the minimum number of test cases required to cover all valid equivalence partitions for calculating the interest?

Which of the following BEST matches the descriptions with the different categories of test techniques? 1. Test cases are based on the test basis which may include the requirements, use cases and user stories 2. Test cases are based on the test basis which may include the software architecture or code 3. Test cases can show deviations from the requirements 4. These test techniques are applicable to both functional and non-functional testing 5. Tests are based on knowledge of developers, users and other stakeholders Black - Black-box test techniques White * White-box test techniques Experience - Experience-based test techniques

Answers
D.
The risks associated with delivering the system are far higher than the cost of testing
Suggested answer: B

Explanation:

Testing is necessary for various reasons, such as:

To detect defects and failures that may affect the quality, performance, reliability or security of a software product or system

To verify that a software product or system meets its specified requirements, expectations and standards

To validate that a software product or system fulfills its intended purpose and satisfies its stakeholders' needs

To provide information and feedback about the status and risks of a software product or system

To comply with regulations or contractual obligations that mandate testing for certain types of software products or systems The following statements describe some reasons why testing is necessary:

A) The customer decided that 100% branch coverage shall be achieved. This is a reason why testing is necessary, as it reflects a contractual obligation or a quality standard that requires testing to measure and achieve a certain level of code coverage.

C) For avionics and pharmaceutical systems software testing is mandated by standards. This is a reason why testing is necessary, as it reflects a regulation or a compliance requirement that mandates testing for certain types of software products or systems that have high safety or security risks.

D) The risks associated with delivering the system are far higher than the cost of testing. This is a reason why testing is necessary, as it reflects a risk-based approach that considers testing as an investment to reduce the probability and impact of potential failures or defects. The following statement does not describe a reason why testing is necessary:

B) The acquisition of test automation tools was based on the assumption that it will be used m all projects. This is not a reason why testing is necessary, as it reflects a business decision or a resource allocation that does not justify the need or purpose of testing. Test automation tools are not always suitable or beneficial for all projects, and testing can be performed with or without test automation tools. Verified
