Instead of having an independent test team within the company, the company is considering to outsource testing. What are THREE key challenges that are typical for outsourcing? 1 credit

A. Test environment more complex

B. Define expectation for tasks and deliverables

C. Clear channels of communications

D. Possibly different cultures

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

A. The quality of the development estimate may be poor.

B. In general bottom-up estimation is always better than top-down estimation.

C. The percentage based technique only applies to the V life cycle model.

D. Using the same percentage every time does not address the level of risk of the application to be tested.

E. The maturity of the organization, e.g. the quality of the test basis, quality of development testing, configuration management, availability of test tools, also influence the effort needed for testing.

F. It builds on large set of historical data

G. The result is almost always a too low estimate for the required test effort

The test improvement project will take place in an organization developing a safety-critical avionics application. Which one of the following standards do you believe would be most appropriate to take into account for compliance during your assignment? 1 credit

A. ISO 9126

B. IEEE 829

C. BS 7925/2

D. DO-178B

Comparing TMMi and TPI, which is not a valid reason for choosing either TPI or TMMi? 2 credits

A. If the scope of test performance improvement covers all test levels, TMMi is preferred since TPI focusses mainly on black-box testing.

B. If the organization is already applying CMMI, TMMi may be preferred since it has the same structure and uses the same terminology. TMMi addresses management commitment very strongly and is therefore more suitable to support a top-down improvement process.

C. TPI is much more a bottom-up model that is suitable for addressing test topics for a specific (test) project.

D. TMMi can only be used with the traditional V model,whereas TPI can be used with all types of software life cycles.

Which THREE activities would be valid steps during the development of the test strategy?2 credits (2 out of 3 correct 1 credit)

A. Identify test staff members that will be involved in the system test

B. Define test career paths

C. Understand the software development life cycle used by the software house

D. Assess the testing that needs to be done to minimize the risks

E. Issue the test strategy document for review

F. Define a master test plan template

G. Perform a project risk analysis

Which of the following product risks would be most effectively addressed just by static testing? 3 credits

A. In the delivered application, one of the countries, as specified in the requirements, has not been correctly implemented.

B. The application takes too long to process a request for additional cover.

C. The test cases do not cover the key requirements.

D. The successful bidder may not deliver all the required functionality on time.
