In general, why is it NOT a good idea to estimate the testing effort based only on a percentage of development effort? Identify THREE valid reasons. 1 credit

1. A. The quality of the development estimate may be poor.
2. B. In general bottom-up estimation is always better than top-down estimation.
3. C. The percentage based technique only applies to the V life cycle model.
4. D. Using the same percentage every time does not address the level of risk of the application to be tested.
5. E. The maturity of the organization, e.
6. F. the quality of the test basis, quality of development testing, configuration management, availability of test tools, also influence the effort needed for testing.
7. G. It builds on large set of historical data
8. H. The result is almost always a too low estimate for the required test effort

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?

1. A. A business analyst who wrote the original requirements for the system.
2. B. A permanent programmer who reviewed some of the new code, but has not written any of it.
3. C. A permanent tester who found most defects in the original system.
4. D. A contract tester who has never worked for the organization before.

Correct Answer: 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.
