CTFL4 Free Practice Test

Which one of the following statements IS NOT a valid objective of testing?

1. A. To build confidence in the level of quality of the test object.
2. B. To find all defects in a product, ensuring the product is defect free.
3. C. To find failures and defects
4. D. To evaluate work products such as requirements, user stories, design, and code.

Correct Answer: B

A calculator software is used to calculate the result for 5+6. The user noticed that the result given is 6.
This is an example of;

1. A. Mistake
2. B. Fault
3. C. Error
4. D. Failure

Correct Answer: D
According to the ISTQB Glossary of Testing Terms, Version 4.0, 2018, page 18, a failure is ??an event in which a component or system does not perform a required function within specified limits??. In this case, the calculator software does not perform the required function of calculating the correct result for 5+6 within the specified limits of accuracy and precision. Therefore, this is an example of a failure.
The other options are incorrect because:
✑ A mistake is ??a human action that produces an incorrect result?? (page 25). A mistake is not an event, but an action, and it may or may not lead to a failure. For example, a mistake could be a typo in the code, a wrong assumption in the design, or a misunderstanding of the requirement.
✑ A fault is ??a defect in a component or system that can cause the component or system to fail to perform its required function?? (page 16). A fault is not an event, but a defect, and it may or may not cause a failure. For example, a fault could be a logical error in the code, a missing specification in the design, or a contradiction in the requirement.
✑ An error is ??the difference between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition?? (page 15). An error is not an event, but a difference, and it may or may not result in a failure. For example, an error could be a rounding error in the calculation, a measurement error in the observation, or a deviation error in the condition.

During which main group of test activity are the following tasks performed?
•Checking test results and logs against specified coverage criteria.
•Assessing the level of component or system quality based on test results and logs.
•Determining whether more tests are needed. Select the correct Answer:

1. A. Test planning.
2. B. Test analysis.
3. C. Test design.
4. D. Test monitoring and control.

Correct Answer: D
The activities of checking test results and logs against specified coverage criteria, assessing the level of component or system quality based on test results and logs, and determining whether more tests are needed fall under the category of test monitoring and control. This phase involves ongoing assessment and adjustment of the test activities to ensure they meet the test objectives and quality goals.

Which of the following about typical information found within a test plan is FALSE?

1. A. The need to temporarily have additional test personnel available for specific test phases and/or test activities
2. B. The conditions that must be met in order for the test execution activities to be considered completed.
3. C. The list of the product risks which have not been fully mitigated at the end of test execution.
4. D. The conditions that must be met for part of all the planned activities to be suspended and resumed.

Correct Answer: C
A typical test plan includes various elements, such as resource requirements, test completion criteria, and suspension/resumption criteria. However, the list of product risks that have not been fully mitigated is generally not included in the test plan but rather in the risk management documentation.
✑ The test plan focuses on planning and executing tests, including resource
allocation and defining criteria for test suspension and resumption.
✑ While risk management is crucial, unmitigated risks are typically documented in risk logs or separate risk management plans.

A typical objective of testing is to ensure that:

1. A. testing is used to drive the development of a software
2. B. a software has been tested using a combination of test techniques
3. C. there are no defects in a software that is about to be released
4. D. a software has been properly covered

Correct Answer: B
This answer is correct because a typical objective of testing is to ensure that a software has been tested using a combination of test techniques, such as black-box, white-box, or experience-based techniques, that are appropriate for the test objectives, test levels, and test types. Testing using a combination of test techniques can increase the effectiveness and efficiency of testing, as different techniques can target different aspects of the software quality, such as functionality, usability, performance, security, reliability, etc. Testing using a combination of test techniques can also reduce the risk of missing defects that could be detected by one technique but not by another.
