What can a risk-based approach to testing provide?
Answer(s): A
When assembling a test team to work on an enhancement to an existing system, which of the following has the highest level of test independence?
Answer(s): D
In this scenario, the contract tester who has never worked for the organization before has the highest level of test independence. The three others are less independent as they are likely to make assumptions based on their previous knowledge of the requirements, code and general functionality of the original system.Note that independence does not necessarily equate to most useful. In practice most test or project managers would recruit a permanent tester who has worked on the original system in preference to a contract tester with no knowledge of the system. However, when assembling a team it would be useful to have staff with varying levels of test independence and system knowledge.
Which of the following terms is used to describe the management of software components comprising an integrated system?
Incident management is the collection and processing of incidents raised when errors and defects are discovered. Test monitoring identifies the status of the testing activity on a continuous basis. Risk management identifies, analyses and mitigates risks to the project and the product. Configuration management is concerned with the management of changes to software components and their associated documentation and testware.
A new system is about to be developed. Which of the following functions has the highest level of risk?
In (B) the product of probability × impact has the value £15,000; in (C) the value is £5,000 and in (D) it is £4,000. The value of £20,000 in (A) is therefore the highest.
Which of the following statements about risks is most accurate?
Answer(s): C
In general, project risk and product risk can be hard to differentiate. Anything that impacts on the quality of the delivered system is likely to lead to delays or increased costs as the problem is tackled. Anything causing delays to the project is likely to threaten the delivered system's quality. The risk- based approach is an approach to managing product risk through testing, so it impacts most directly on product risk.
