Consider the following statements about early test design:
i. Early test design can prevent fault multiplication
ii. Faults found during early test design are more expensive to fix
iii. Early test design can find faults
iv. Early test design can cause changes to the requirements
v. Early test design takes more effort

• A.i, iii, iv & v are true, ii us false
• B.i, iii & iv are true. ii & v are false
• C.i & iii are true, ii, iv & v are false
• D.iii & iv are true. i, ii & v are false
• E.iii is true, i, ii, iv & v are false

A bank is developing a new service that will be delivered via the web. The user interactions are defined as a set of use cases and the service is designed to be available continuously 24/7. In view of the challenging characteristics of the service the test manager has decided that the code should be thoroughly tested at component level.
Which of the following test types will be required during the development?

• A.Functional testing to test the use cases at component level, reliability testing to test availability at the integration level, regression testing at the system testing level only, structure based testing at all levels
• B.Functional testing to test security at the system level, load testing at the system level to ensure the system availability is acceptable, regression testing at all levels, structure based testing at the component level only
• C.Functional testing to test security at the acceptance level, load testing at the acceptance test level to ensure availability is acceptable, regression testing at the acceptance level only to ensure late changes are made correctly, and structure based testing at the component level
• D.Functional testing of the use cases at system level, load testing at component level to ensure availability is acceptable, regression testing at the system and acceptance levels only, and structure based testing at the integration level only

A software component has the code shown below:
Program BiggestA,
Biggest: Integer
Begin
Read A
Biggest = 10
While A > 0
Do
If A > Biggest
Then Biggest = A
Endif
Read A
Enddo
End
The component has exit criteria for component testing that include 100% statement coverage.
Which of the following test cases will satisfy this criterion?

• A.10, 5, 0
• B.0
• C.10, 11, 0
• D.10, 0

Which of the following is a key difference between black box and white box test design techniques?

• A.White box techniques derive test cases from models of the software, black box techniques do not.
• B.White box techniques use functional design specifications to derive test cases, black box techniques do not.
• C.Black box techniques use software code to derive test cases, white box techniques do not.
• D.White box techniques can measure the extent of code coverage, black box techniques can not.

Statement Coverage will not check for the following:

• A.Unused Statement
• B.Unused Branches
• C.Dead Code
• D.Missing Statements
