Which ONE of the following statements does NOT describe how testing contributes to higher quality?

• A.Performing a review of the requirement specifications before implementing the system can enhance quality.
• B.The testing of software demonstrates the absence of defects.
• C.Properly designed tests that pass reduce the level of risk in a system.
• D.Software testing identifies defects, which can be used to improve development activities.

The statement: "Test activities should start in the early stages of the lifecycle, adhering to the testing principle of early testing" is relevant to which of the recognized software development models?

• A.Incremental development model.
• B.Sequential development model.
• C.All the above
• D.Iterative development model.

For each test case to be executed, the following table specifies its dependencies and the required configuration of the test environment for running such test case:

Assume that C0NF1 is the initial configuration of the test environment Based on this assumption, which of the following is a test execution schedule that is compatible with the specified dependencies and allows minimising the number of switches between the different configurations of the test environment^

• A.TC4, TC3, TC2, TC1, TC5.
• B.TC4, TC1, TC5, TC2, TC3
• C.TCI, TC5, TC4, TC3, TC2
• D.TC4, TC3, TC2, TC5, TC1.

Following a risk-based testing approach you have designed 10 tests to cover a product risk with a high-risk level. You want to estimate, adopting the three-point test estimation technique, the test effort required to reduce the risk level to zero by executing those 10 tests. You made the following three initial estimates:
* most optimistic = 6 person hours
* most likely = 30 person hours
* most pessimistic = 54 person hours
Based only on the given information, which of the following answers about the three-point test estimation technique applied to this problem is true?

• A.The final estimate is exactly 30 person hours because the technique uses the arithmetic mean of the three initial estimates as the final estimate
• B.The final estimate is exactly 30 person hours because the technique uses the initial most likely estimate as the final estimate
• C.The final estimate is between 22 person hours and 38 person hours
• D.The final estimate is between 6 person hours and 54 person hours

As a tester, as part of a V-model project, you are currently executing some tests aimed at verifying if a mobile app asks the user to grant the proper access permissions during the installation process and after the installation process. The requirements specification states that in both cases the app shall ask the user to grant access permissions only to the camera and photos stored on the device. However, you observe that the app also asks the user to grant access permission to all contacts on the device. Consider the following items:
[I]. Test environment
[ii]. Expected result
[iii]. Actual result.
[IV] Test level.
[V]. Root cause.
Based on only the given information, which of the items listed above, are you able to CORRECTLY specify in a defect report?

• A.[l] and [IV]
• B.[ii], [IV] and [V].
• C.[ii] and [III].
• D.[ii], [iii] and [v]
