Answer
  • Boolean or discrete values / different types
  • Discrete values only / different types
  • Discrete value only / same types
  • Boolean or discrete values / same types

Question 11

Question
The common minimum coverage standard for decision table testing is...
Answer
  • To have at least two test cases per decision rule in the table
  • To have at least one test case per decision rule in the table
  • To have at least four test cases per decision rule in the table
  • To have at least three test cases per decision rule in the table

Question 12

Question

  • One or more actors
  • Only two actors

Question 17

Question
Which of the following statements is true and which is false about “use cases testing’’ ? 1. A use case can be described as interactions, activities and preconditions 2. Use cases can include possible variations as error handling 3. Code is designed to exercise the defined behaviours
Answer
  • 1, 2, 3 are true
  • 1 is true / 2, 3 are false
  • 1, 2, 3 are false
  • 1, 2 are true / 3 is false

Question 18

Question
What is the meaning of achieving 100% statement coverage?
Answer
  • Test cases are designed to pass through all the statements of inputs
  • Test cases are designed to pass through all the executable statements of executable code
  • Test cases are designed to pass through all the statements of requirements

Question 19

Question
How to measure statement testing coverage?
Answer
  • Number of statements covered by tests, divided by the total number of statements
  • Number of statements, divided by number of statements covered by tests
  • Number of decisions covered by tests, divided by the total number of decisions

Question 20

Question
How to measure decision testing coverage ?
Answer
  • Number of statements covered by tests, divided by the total number of statements
  • Total number of statements, divided by number of statements covered by tests
