Question (1 Point)

Which of the following BEST explains a benefit of independent testing?

Select ONE option.

The use of an independent test team allows project management to assign responsibility for the quality of the final deliverable to the test team, so ensuring everyone is aware that quality is the test team’s overall responsibility

If a test team external to the organization can be afforded, then there are distinct benefits in terms of this external team not being so easily swayed by the delivery concerns of project management and the need to meet strict delivery deadlines

An independent test team can work totally separately from the developers, need not be distracted with changing project requirements, and can restrict communication with the developers to defect reporting through the defect management system

When specifications contain ambiguities and inconsistencies, assumptions are made on their interpretation, and an independent tester can be useful in questioning those assumptions and the interpretation made by the developer

15.

Error guessing involves using your personal experience of development and the mistakes you made as a developer

Error guessing involves using your knowledge and experience of defects found in the past and typical mistakes made by developers

Error guessing requires you to rapidly duplicate the development task to identify the sort of mistakes a developer might make

19.

Question (1 Point)

Which of the following statements CORRECTLY reflects the value of static testing?

Select ONE option.

By introducing reviews, we have found that both the quality of specifications and the time required for development and testing have increased

Using static testing means we have better control and cheaper defect management due to the ease of detecting defects later in the lifecycle

Now that we require the use of static analysis, missed requirements have decreased and communication between testers and developers has improved

Since we started using static analysis, we find coding defects that might have not been found by performing only dynamic testing
