Q32. Which of the following are valid reasons for adopting a different life cycle (from the V model), for increments after the first year? 2 credits
i. We do not have a clear understanding of the requirements from a customer perspective.
ii. We see the risk of delivering requested functionality late as being higher than the risk of delivering a lower quality product.
iii. We do not have a budget for additional regression testing which is needed to ensure that existing functionality is not compromised by future iterations.
iv.
The company test strategy does not fit well within the V life cycle model.

(i) and (ii)

Q33. Which test management control option is most appropriate to adopt under these circumstances? 2 credits

Introduce mandatory evening and weekend working to retrieve the 3 week slippage.

Reconsider the exit criteria and review the test plan in the context of the current situation.

Advise the user community regarding the reduced scope of requirements and the additional incremental delivery.

Arrange a meeting with the user community representatives to discuss the user interface.

Q34. 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

ISO 9126

IEEE 829

BS 7925/2

DO-178B

Q35. Which of the following statements about software development models is most accurate?
[K1]

The 4 stage V model is always the best choice of software development model for any project

The agile development model is usually most appropriate for short projects

The choice of software development model depends on product and project characteristics

The 2 stage V model is the most appropriate development model for simple products

Q36. The flow graph below shows the logic of a program for which 100% statement coverage and 100% decision coverage is required on exit from component testing.
The following test cases have been run:
Test Case 1 covering path P,Q,R,U
Test Case 2 covering path P,Q,S,V
Test Case 3 covering path P,Q,S,W,X
Test case 4 covering path P,Q,S,W,Y
Refer to the exhibit

Statement coverage is 100%; decision coverage is 100%

Statement coverage is less than 100%; decision coverage is 100%.

Statement coverage is 100%; decision coverage is less than 100%

Statement coverage and decision coverage are both less than 100%

Q37. When what is visible to end-users is a deviation from the specific or expected behavior, this is called..?

An error

A fault

A failure

A defect

A mistake

Q38. What is the value of static code analysis?

Detection of failures not easily found by other types of testing

Early defect detection

Detection of suspicious operations caused by deviations from regulations

Detect deviations in standards by executing the source code

Q39. Which of the following type of defect would NOT be typically found by using a static analysis tool?

A variable is defined but is then not used

A variable is used in a calculation before it is defined

A variable has the wrong numeric value passed into it

A variable is used but not declared

Q40. Statement Coverage will not check for the following:

Missing Statements

Unused Branches

Dead Code

Unused Statement

Q41. Consider the typical objectives of testing. Which of the following metrics can be used to measure the effectiveness of the testing process in achieving one of those objectives?

Average number of days between defect discovery and resolution

Percentage of requirements covered

Lines of code written per developer per day

Percentage of test effort spent on regression testing

Q42. Component testing may include:

Sociability testing.

User acceptance testing.

Beta testing.

The use of stubs and drivers.

Q43. Test objectives for systems testing of a safety critical system include completion of all outstanding defect correction. Regression testing is required following defect correction at all test levels. Which TWO of the following metrics would be MOST suitable for determining whether the test objective has been met? [K2] a. Regression tests run and passed in systems testing
b. Incidents closed in systems testing
c. Planned tests run and passed in system testing
d. Planned tests run and passed at all levels of testing
e. Incidents raised and closed at all levels of testing

a and e

b and c

d and e

a and b

Q44. What is static analysis?

The decision between using white or black box test techniques.

Executing software to validate the most common path through the code.

A technique to find defects in software source code and software models, performed without executing code.

It is a testing technique used during system testing.

Q45. Which of the following characteristics is most likely to promote effective software testing? [K1]

Independence from the production process

A belief that programmers always make mistakes

Knowledge of the number of defects typically found in a program

Confidence that the next stage will find defects missed at this stage

Q46. Which of the following is most likely to be a benefit of using static techniques?

Fewer performance defects.

Productivity improvements in the development process.

More efficient regression testing.
