Which of the following is NOT true of incidents?
technology testing

  1. a) Incident resolution is the responsibility of the author of the software under test.

  2. b) Incidents may be raised against user requirements.

  3. c) Incidents require investigation and/or correction.

  4. d) Incidents are raised when expected and actual results differ.

Show answer
Correct Option: A
Explanation:

To correctly answer this question, the user should understand the definition of an incident in software testing and the typical characteristics of an incident.

An incident refers to any event that occurs during the testing of software that requires further investigation, such as when the actual results differ from the expected results.

Option A: This statement is incorrect. Resolution of incidents is not the sole responsibility of the author of the software under test. Various team members, such as developers, testers, and project managers, may be involved in resolving incidents.

Option B: This statement is correct. Incidents may be raised against user requirements when there is a deviation from the expected behavior or when the system fails to meet the specified requirements.

Option C: This statement is correct. Incidents require investigation and/or correction. When an incident is raised, it must be investigated to determine its cause and corrected to ensure that the software functions as expected.

Option D: This statement is correct. Incidents are raised when expected and actual results differ. When a test case is executed, the expected results are compared to the actual results. If they differ from each other, an incident is raised.

Therefore, the correct answer is:

The Answer is: A

Which of the following is false?
technology testing

  1. a) In a system two different failures may have different severities.

  2. b) A system is necessarily more reliable after debugging for the removal of a fault.

  3. c) A fault need not affect the reliability of a system.

  4. d) Undetected errors may lead to faults and eventually to incorrect behaviour.

Show answer
Correct Option: B

Which of the following is true of the V-model?
technology testing

  1. a) It states that modules are tested against user requirements.

  2. b) It only models the testing phase.

  3. c) It specifies the test techniques to be used.

  4. d) It includes the verification of designs.

Show answer
Correct Option: D
Explanation:

To answer this question, the user needs to know what the V-model is and its characteristics.

The V-model is a software development model that illustrates the relationship between each phase of the development life cycle and its corresponding testing phase. The model is called the V-model because it takes the shape of the letter "V".

Now, let's go through each option and explain why it is right or wrong:

A. It states that modules are tested against user requirements. This statement is incorrect. The V-model specifies that each phase of the development life cycle has a corresponding testing phase. The testing phase in the V-model is not limited to testing modules against user requirements.

B. It only models the testing phase. This statement is incorrect. The V-model models the entire software development life cycle, including requirements gathering, design, coding, and testing.

C. It specifies the test techniques to be used. This statement is incorrect. While the V-model provides guidance on the testing phase, it does not specify the exact test techniques to be used.

D. It includes the verification of designs. This statement is correct. The V-model includes the verification of designs as part of the development life cycle. The model specifies that testing should start at the beginning of the development life cycle, with the verification of requirements, and continue through the design, coding, and testing phases.

Therefore, the answer is: D.

We split testing into distinct stages primarily because:

technology testing

  1. a) Each test stage has a different purpose.

  2. b) It is easier to manage testing in stages.

  3. c) We can run different tests in different environments

  4. d) The more stages we have, the better the testing.

Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the reasons for splitting testing into distinct stages. Let's go through each option to understand why it is correct or incorrect:

Option A) Each test stage has a different purpose. - This option is correct because splitting testing into distinct stages allows us to focus on specific aspects or objectives of testing at each stage. Different stages can target different types of testing, such as unit testing, integration testing, system testing, and acceptance testing. Each stage serves a specific purpose and helps ensure that different aspects of the software are thoroughly tested.

Option B) It is easier to manage testing in stages. - This option is incorrect. While it is true that dividing testing into stages can help with managing the testing process, this is not the primary reason for splitting testing into stages. The primary reason is to address different testing objectives at each stage.

Option C) We can run different tests in different environments. - This option is not directly related to the primary reason for splitting testing into stages. Running different tests in different environments can be a factor in testing, but it is not the main reason for dividing testing into stages.

Option D) The more stages we have, the better the testing. - This option is incorrect. The number of stages does not necessarily determine the quality of testing. The effectiveness of testing depends on how well each stage is designed and executed, not solely on the number of stages.

The correct answer is A) Each test stage has a different purpose. This option is correct because splitting testing into distinct stages allows us to focus on specific aspects or objectives of testing at each stage. Each stage serves a specific purpose and helps ensure that different aspects of the software are thoroughly tested.
