Question 20

Question
Consider the following statements: v. White-box testing eliminates the need for black-box testing w. Multiple condition testing is another name for decision testing x.100% decision coverage guarantees 100% statement coverage y.100% statement coverage guarantees 100% decision coverage
Answer
  • x is true, others are false
  • x & y are true, v & w are false
  • x & y are false, v & w are true
  • y is false, others are true

Question 21

Question
Which of these statements about test techniques is incorrect?
Answer
  • Decision testing is a structural technique and has a measure attached
  • Equivalence partitioning is the same category of technique as boundary value analysis
  • State transition testing is the same category of technique as statement testing

Question
Which is true of error guessing?
Answer
  • It is the best way to derive test cases
  • It is best used after more formal techniques have been applied
  • It is used by inexperienced testers
  • It should only be used when there is insufficient time to apply more formal techniques

Question 24

Question
Fault Attack is:
Answer
  • A structured approach to error guessing

Question 25

Question
The test techniques chosen are influenced by:
Answer

  • The level of risk and regulatory requirements
  • The size of the system and the test tools available
  • The preferences of the project manager

Question 26

Question
is described here? ‘An informal test design technique where the tester actively controls the design of the tests as those tests are performed and uses information gained while testing to design new and better tests’
Answer
  • Static testing
  • Error guessing
  • Fault attack
  • Exploratory testing
