A booking system for a city bus service prices its fares according to the time of travel:

?Peak-time tariff starts at 0600 and finishes at 1000 am ?Off-peak tariff applies during all other times of

service ?The bus service does not operate between 2300 and the start of the next day's peak service Note

Why is measurement of code coverage Important?

A. Because 100% code coverage implies 100% coverage of requirements

B. Because 100% code coverage guarantees that there are no coding errors

C. Because code coverage can be used to ensure that all code is exercised by tests

D. Because code coverage can ensure that all decisions are correctly implemented in the code

Which of the following defects-can NOT be found by static analysis tools?

A. Infinite loops

B. Wrong business rules

C. Syntax errors of the code

D. Undefined variables

Which of the following test execution outcomes are likely to increase the overall quality of the software: I) A test case passes II) A test case fails, defect gets logged which subsequently gets fixed III) Some tests are deferred because test environment is not available IV) A bug is found but there is no corresponding test case

A. I, II and III

B. I and IV

C. I and II

D. I, II and IV

Which of the following statements is true?

A. 100% branch coverage means 100% statement coverage.

B. 100% statement coverage means 100% branch coverage.

C. 100% branch coverage means 100% statement coverage and vice-versa.

D. It is impossible to achieve 100% statement coverage

Which of the following would be a key difference between a peer review of code and static analysis of code using a tool?

A. A peer reviews finds defects while static analysis finds failures

B. Peer reviews cannot find missing requirements whereas static analysis can

C. A peer reviews find failures while static analysis finds defects

D. Static analysis targets the code technically whereas Peer review is applicable to further aspects.

What is a peer review?

B. A review done by developers and testers together

C. A review done by developers only

D. A review done by colleagues at the same organizational level

B. Dynamic testing finds defects, while debugging removes failures

C. Dynamic testing reveals failures, while debugging removes defects

D. Like most development activities, debugging is usually done before testing starts

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

A. Black box techniques use software code to derive test cases, white box techniques do not.

B. White box techniques use functional design specifications to derive test cases, black box techniques do not.

C. White box techniques can measure the extent of code coverage, black box techniques can not.

D. White box techniques derive test cases from models of the software, black box techniques do not.

Which of the following is an approach that can be used for exploratory testing?

C. A tester analyses, designs and implements tests based on external rules and standards.

D. Tests are designed based on the guidance of stakeholders and experts outside the test team.
