You wish to perform a test which completely covers all the combinations of equivalence Partitioning for the different types of credit card according to the rules shown in the above Decision Table. How many test cases do you need?
- A.
16
- B.
8
- C.
12
- D.
4
Correct Answer
A. 16Explanation
The correct answer is 16. This is because the decision table shows 2 conditions (valid card number and purchase approved) with 2 possible values (NO and YES) each. Therefore, there are 2^2 = 4 possible combinations of these conditions. Additionally, there are 2 actions (reject message and accept payment) with 2 possible values (YES and NO). So, there are 2^2 = 4 possible combinations of these actions. Multiplying the combinations of conditions and actions together, we get 4 * 4 = 16 possible test cases needed to cover all combinations.Rate this question:

- B.
0.2,0.9,29.5
- C.
0.1,0.4,24,25
- D.
0.4,0.5,25.0,25.1
Correct Answer
D. 0.4,0.5,25.0,25.1Explanation
Equivalence partitioning is a testing technique that divides input data of a software program into partitions of equivalent data from which test cases can be derived. In essence, it aims to reduce the number of test cases to a minimum necessary set that still covers all scenarios.
Given the conditions that the smallest valid order is 0.5 units and the largest valid order is 25 units, we would want to test:
Below the valid range
Within the valid range at the lower boundary
Within the valid range but not at the boundary
At the upper boundary of the valid range
Above the valid range
The set 0.4, 0.5, 25.0, 25.1 represents:
0.4: Just below the valid range, testing the system's response to an order too small.
0.5: The smallest valid order, testing the acceptance of the minimum valid order.
25.0: The largest valid order, testing the acceptance of the maximum valid order.
25.1: Just above the valid range, testing the system's response to an order too large.Rate this question:

The work breakdown structure (WBS) is least likely to be used as a basis for estimating testing effort because it is a project management tool that breaks down the project into smaller, manageable components. While it helps in organizing and planning the project tasks, it does not directly relate to estimating the effort required for testing. On the other hand, factors like the quality of the test basis, skills of the test team, and requirements for documentation are more relevant in estimating testing effort as they directly impact the complexity and scope of the testing process.Rate this question:

Which of the following sentences describes best what "Functional Testing" is? Select one:
- A.
A test focused on the efficient interactions among different parts of the system.
- B.
A test in which the test cases and test data are based on the program structure of the test object
- C.
A static comparison of test and requirements specification of a test object
- D.
A dynamic test which is based on the specification of the test object
Correct Answer
D. A dynamic test which is based on the specification of the test objectExplanation
Functional testing is a type of testing that focuses on the dynamic behavior of a system based on its specifications. It involves testing the interactions and functionality of different parts of the system to ensure that it is working as intended. This type of testing is not based on the program structure or a static comparison of test and requirements specifications. Therefore, the correct answer is that functional testing is a dynamic test based on the specification of the test object.Rate this question:

Consider the code fragment given below. Input a; If(a>100) { a=a-100; if(a>50) { a=a-50; } } else if (a<100) { Print “ Invalid Input”; } Which answer choice would be correct if this program is executed for a=200, a=110, a=0, and a=50?
- A.
100% statement coverage has been achieved but 100% decision coverage has not been achieved
- B.
100% decision coverage has been achieved but 100% statement coverage has not been achieved
- C.
100% statement and 100% decision coverage have been achieved
Correct Answer
C. 100% statement and 100% decision coverage have been achievedExplanation
a = 200:
a > 100 is true, so a becomes 100 (200 - 100).
Now a > 50 is true, so a becomes 50 (100 - 50).
a = 110:
a > 100 is true, so a becomes 10 (110 - 100).
Now a > 50 is false, so the inner block is not executed.
a = 0:
a < 100 is true, so "Invalid Input" is printed.
a = 50:
a < 100 is true, so "Invalid Input" is printed.
Coverage Analysis:
Statement Coverage:
All statements (including the print statement) are executed across the given inputs.
Decision (Branch) Coverage:
All decision points (conditions) a > 100, a > 50, and a < 100 are evaluated as both true and false at least once across the given inputs.
Since all statements and decisions have been executed:
Answer:
100% statement and 100% decision coverage have been achieved.Rate this question:
