• AA. Average number of days between defect discovery and resolution
• BB. Percentage of requirements covered
• CC. Lines of code written per developer per day
• DD. Percentage of test effort spent on regression testing

Which of the following would you least expect to form part of the analysis of initial tool costs? 1 credit

• AA. Integration with other tools
• BB. Learning time required to use the new tool
• CC. Tool portability
• DD. Evaluation of suitable tools

Which of the following is a project risk mitigation step you might take as test manager? 1 credit

• AA. Testing for performance problems
• BB. Hiring a contractor after a test analyst leaves the company
• CC. Arranging a back-up test environment in case the existing one fails during testing
• DD. Performing a project retrospective meeting using the test results after each increment

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

Select 3 answers.

• AA. The quality of the development estimate may be poor.
• BB. In general bottom-up estimation is always better than top-down estimation.
• CC. The percentage based technique only applies to the V life cycle model.
• DD. Using the same percentage every time does not address the level of risk of the application to be tested.
• EE. 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.
• FF. It builds on large set of historical data
• GG. The result is almost always a too low estimate for the required test effort

During test process improvement it is recommended to use standards where possible. Standards originate from various sources and they cover different subjects in relation to testing Pick TWO sources of software standards, useful to software testing from the ones mentioned below. 1 credit

Select 2 answers.

• AA. ISO 9126-1 ‘Software engineering- Product quality Part 1:Quality model’ is an international standard, that provides a basis on which to define quality assurance solutions.
• BB. ISA 4126-1 ‘Software engineering- Product quality Part 1:Quality model’ is an international standard, that provides a basis on which to define quality assurance solutions.
• CC. BS-7925-2 ‘Software testing. Software component testing is a national standard used internationally. It covers a number of testing techniques that may be useful both on component testing level and on system testing level.
• DD. SY-395-01 ‘Standard for East Coast Hospital software’ is a regional standard adapted from a national one. Besides hospital software, this standard ought to be used also by other types of software system in the region.
• EE. IEEE 829 ‘standard for software test documentation’ is an international standard to be followingmandatory by all testing origination regardless of lifecycle models.
