NEW QUESTION # 134
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;
Answer: A
Explanation:
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.
NEW QUESTION # 135
Which of the following statements about static testing and dynamic testing is true?
Answer: D
Explanation:
Dynamic testing requires the execution of the software to evaluate its behavior and performance. In contrast, static testing involves examining the software's code, design, and documentation without executing the software. This makes static testing applicable to non-executable work products such as requirement documents, design documents, and source code.
NEW QUESTION # 136
An anti-intrusion system is battery powered and is activated by pressing the only available button. To deactivate the system, the operator must enter a PIN code. The system will stay in alert mode within a configurable timeout and an alarm bell will ring if the system is not deactivated before the timeout expires.
The following state transition diagram describes the behavior of the system:
What is the minimum number of test cases needed to cover every unique sequence of exactly 4 states/3 transitions starting and ending in the "Inactive" state? (note that "Inactive" is not a final state in the diagram)
Answer: B
Explanation:
In the given state transition diagram, we need to identify the minimum number of test cases required to cover every unique sequence of exactly 4 states/3 transitions starting and ending in the "Inactive" state.
The states are:
* Inactive
* Active
* Alert Mode
* Alarm bell rings
* Inactive -> Active -> Inactive -> Active -> Inactive
* Sequence: Press Button, Enter PIN, Press Button, Enter PIN
* Inactive -> Active -> Alert Mode -> Inactive
* Sequence: Press Button, Sensor Activated, Enter PIN
* Inactive -> Active -> Alert Mode -> Alarm bell rings -> Inactive
* Sequence: Press Button, Sensor Activated, Timeout expired, Press Button Test Case Analysis:These sequences cover every unique combination of exactly 4 states and 3 transitions starting and ending in the "Inactive" state.

NEW QUESTION # 137
A requirement specifies that if the total amount of sales (TAS) made during the year by a corporate seller is 300,000 or more, the bonus that must be paid to the seller is 100% of a certain amount agreed upon at the beginning of the year. The software contains a fault as it implements this requirement with the decision "IF (TAS = 300,000)" instead of "IF (TAS >= 300.000)". The application of the 3-value boundary value analysis to this problem consists of the following three test cases (TAS is an integer variable):
TC1 = 299,999 TC2=300,000 TC=300,001
Which of the following statements is TRUE?
Answer: B
Explanation:
The fault in the software is that it checks only for TAS = 300,000 rather than TAS >= 300,000.
This means the bonus is paid only if the TAS is exactly 300,000, not when it exceeds 300,000 as intended.
With boundary value analysis, we test the values just below, at, and just above the boundary condition:
TC1 (TAS = 299,999): No bonus is expected, so this test case would not expose the fault.
TC2 (TAS = 300,000): The software would pay the bonus correctly according to its faulty condition, so this would not expose the fault either.
TC3 (TAS = 300,001): According to the requirement, the bonus should be paid, but the software's faulty condition will not pay the bonus because it only checks for TAS exactly equal to 300,000.
Therefore, TC3 would highlight the fault by demonstrating that the bonus is not paid when TAS is greater than 300,000, which contradicts the requirement.
NEW QUESTION # 138
In which software development lifecycle does the tester participate in requirement reviews and test design in the initial phases, and in dynamic testing in later phases?
Answer: D
Explanation:
In sequential development models, such as the V-model, testing activities are planned early.
Testers participate in reviewing requirements and designing tests during the initial phases, while dynamic testing is performed later after the corresponding development activities have been completed.
