BCS ISTQB Certified Tester Foundation Level CTFL 4.0 Sample Questions (Q48-Q53):

NEW QUESTION # 48
A program is used to control a manufacturing line (turn machines on and off. start and stop conveyer belts, add raw materials to the flow. etc.). Not all actions are possible at all times. For example, there are certain manufacturing stages that cannot be stopped - unless there is an emergency. A tester attempts to evaluate if all such cases (where a specific action is not allowed) are covered by the tests.
Which coverage metric will provide the needed information for this analysis?

  • A. Data flow coverage
  • B. Code coverage
  • C. Branch Coverage
  • D. Statement coverage

Answer: C

Explanation:
Branch coverage is a type of structural coverage metric that measures the percentage of branches or decision outcomes that are executed by the test cases. A branch is a point in the code where the control flow can take two or more alternative paths based on a condition. For example, an if-else statement is a branch that can execute either the if-block or the else-block depending on the evaluation of the condition. Branch coverage ensures that each branch is taken at least once by the test cases, and thus reveals the behavior of the software under different scenarios. Branch coverage is also known as decision coverage or all-edges coverage.
Branch coverage is suitable for testing the cases where a specific action is not allowed, because it can verify that the test cases cover all the possible outcomes of the conditions that determine the action. For example, if the program has a condition that checks if the manufacturing stage can be stopped, then branch coverage can ensure that the test cases cover both the cases where the stage can be stopped and where it cannot be stopped. This way, branch coverage can help identify any missing or incorrect branches that may lead to undesired or unsafe actions.
The other options are not correct because they are not suitable for testing the cases where a specific action is not allowed. Code coverage is a general term that encompasses various types of coverage metrics, such as statement coverage, branch coverage, data flow coverage, etc. Code coverage does not specify which type of coverage metric is used for the analysis. Data flow coverage is a type of structural coverage metric that measures the percentage of data flow paths that are executed by the test cases. A data flow path is a sequence of statements that define, use, or kill a variable. Data flow coverage is useful for testing the correctness and completeness of the data manipulation in the software, but not for testing the conditions that determine the actions. Statement coverage is a type of structural coverage metric that measures the percentage of statements or lines of code that are executed by the test cases. Statement coverage ensures that each statement is executed at least once by the test cases, but it does not reveal the behavior of the software under different scenarios. Statement coverage is a weaker criterion than branch coverage, because it does not account for the branches or decision outcomes in the code.

NEW QUESTION # 49
Which of the following statements best describes the difference between product risk and project risk in software testing?

  • A. Product risk refers to the risk associated with the project's schedule, budget, and resources, while project risk refers to the risk associated with the quality and functionality of the software product.
  • B. Product risk and project risk are essentially the same and can be used interchangeably.
  • C. Product risk refers to the risk associated with delays in elements such as work product deliveries and inaccurate estimates, while project risk refers to the risk associated with issues such as user dissatisfaction.
  • D. Product risk refers to the risk associated with issues such as delays in work product deliveries, inaccurate estimates, while project risk refers to the risk associated with the project's schedule, budget, and resources.

Answer: D

Explanation:
Product risk involves the potential issues that can affect the quality and functionality of the software product, such as defects, performance problems, and usability issues. Project risk, on the other hand, relates to the risks that can impact the project's schedule, budget, and resources, such as delays, cost overruns, and resource constraints. Understanding both types of risks is crucial for managing and mitigating potential problems in software projects.


NEW QUESTION # 50
Consider the following user story about an e-commerce website's registration feature that only allows registered users to make purchases ; As a new user, I want to register to the website, so that I can start shopping online" The following are some of the acceptance criteria defined for the user story
[a] The registration form consists of the following fields: username, email address, first name, last name, date of birth, password and repeat password.
[b] To submit the registration request, the new user must fill in all the fields of the registration form with valid values and must agree to the terms and conditions.
[c] To be valid, the email address must not be provided by free online mail services that allow to create disposable email addresses. A dedicated error message must be presented to inform the new user when an invalid address is entered.
[d] To be valid, the first name and last name must contain only alphabetic characters and must be between 2 and 80 characters long A dedicated error message must be presented to inform the new user when an invalid first name and/or the last name is entered
[e] After submitting the registration request, the new user must receive an e-mail containing the confirmation link to the e-mail address specified in the registration form Based only on the given information, which of the following ATDD tests is MOST LIKELY to be written first?

  • A. The new user enters valid values in the fields of the registration form, except for the email address, where he/she enters an e-mail address provided by a free online mail service that allow to create disposable email addresses. Then he/she is informed by the website about this issue.
  • B. The new user enters valid values in all the fields of the registration form, confirms to accept all the terms and conditions, submits the registration request and then receives an e-mail containing the confirmation link to the e-mail address specified in the registration form
  • C. The new user enters valid values in the fields of the registration form, except for the first name, where he/she enters a first name with 10 characters that contains a number. Then he/she is informed by the website about this issue.
  • D. The user accesses the website with a username and password, and successfully places a purchase order for five items, paying by Mastercard credit card

Answer: B

Explanation:
Acceptance Test-Driven Development (ATDD) tests focus on verifying whether the system meets the specified acceptance criteria. The most critical path to test first would be the scenario where everything is done correctly (happy path), ensuring the basic functionality works as expected.
The new user provides all valid data.
This ensures the registration form works and the user receives a confirmation email.
This test covers the basic functionality and will help verify that the primary use case is handled correctly before testing invalid or edge cases.


NEW QUESTION # 51
Which of the following statements about branch coverage is true?

  • A. The minimum number of test cases needed to achieve full branch coverage, is usually lower than that needed to achieve full statement coverage
  • B. Exercising at least one of the decision outcomes for all decisions within the code, ensures achieving full branch coverage
  • C. If full branch coverage has been achieved, then all combinations of conditions in a decision table have surely been exercised
  • D. If full branch coverage has been achieved, then all unconditional branches within the code have surely been exercised

Answer: B

Explanation:
Exercising at least one of the decision outcomes for all decisions within the code, ensures achieving full branch coverage, which is a test coverage criterion that requires that all branches in the control flow of the code are executed at least once by the test cases. A branch is a basic block of code that has a single entry point and a single exit point, and a decision is a point in the code where the control flow can take more than one direction, such as an if-then-else statement, a switch-case statement, a loop statement, etc. The decision outcomes are the possible paths that can be taken from a decision, such as the then branch or the else branch, the case branch or the default branch, the loop body or the loop exit, etc. The other statements are false, because:
The minimum number of test cases needed to achieve full branch coverage, is usually higher than that needed to achieve full statement coverage, which is a test coverage criterion that requires that all executable statements in the code are executed at least once by the test cases. This is because branch coverage is a stronger criterion than statement coverage, as it implies statement coverage, but not vice versa. For example, a single test case can achieve full statement coverage for an if-then-else statement, but two test cases are needed to achieve full branch coverage, as both the then branch and the else branch need to be exercised.
If full branch coverage has been achieved, then all unconditional branches within the code have not necessarily been exercised, as unconditional branches are branches that do not depend on any decision, and are always executed, such as a goto statement, a break statement, a return statement, etc. Unconditional branches are not part of the branch coverage criterion, as they do not represent different paths in the control flow of the code. However, they are part of the statement coverage criterion, as they are executable statements in the code.
If full branch coverage has been achieved, then all combinations of conditions in a decision table have not necessarily been exercised, as a decision table is a test design technique that represents the logical relationships between multiple conditions and their corresponding actions, in a tabular format. A decision table can have more combinations of conditions than the number of decision outcomes in the code, as each condition can have two or more possible values, such as true or false, yes or no, etc. For example, a decision table with four conditions can have 16 combinations of conditions, but the corresponding code may have only two decision outcomes, such as pass or fail. To exercise all combinations of conditions in a decision table, a stronger test coverage criterion is needed, such as condition combination coverage, which requires that all possible combinations of condition outcomes in the code are executed at least once by the test cases.
