How many test cases are necessary to cover all the possible sequences of statements (paths) for the following program fragment? Assume that the two conditions are independent of each other : if (Condition 1) then statement 1 else statement 2 if (Condition 2) then statement 3
- A.
2 Test Cases
- B.
3 Test Cases
- C.
4 Test Cases
- D.
Not achievable
Correct Answer
A. 2 Test CasesExplanation
The given program fragment consists of two if-else statements. Each statement has two possible outcomes (true or false) based on the conditions. Since the conditions are independent of each other, the number of test cases required to cover all possible sequences of statements is the product of the number of outcomes for each statement. In this case, the first statement has 2 outcomes and the second statement has 2 outcomes as well. Therefore, the total number of test cases needed is 2 x 2 = 4. However, the correct answer is 2 test cases, which suggests that there is an overlapping or redundancy in the possible sequences of statements, making it achievable with fewer test cases.Rate this question:

D. Exhaustive testingExplanation
Exhaustive testing is not a testing principle because it is not feasible or practical to test every possible combination and permutation of inputs and scenarios. It is time-consuming, expensive, and often unnecessary. Instead, testing efforts should focus on identifying the most critical and high-risk areas to test, prioritizing test cases, and using techniques such as risk-based testing to ensure adequate coverage.Rate this question:

‘X’ has given a data on a person age, which should be between 1 to 99. Using BVA which is the appropriate one
- A.
0,1,2,99
- B.
1, 99, 100, 98
- C.
0, 1, 99, 100
- D.
–1, 0, 1, 99
Correct Answer
C. 0, 1, 99, 100Explanation
Using Boundary Value Analysis (BVA), the appropriate test cases would be the values just above and below the boundaries. In this case, the boundaries are 1 and 99. Therefore, the appropriate test cases would be 0, 1, 99, and 100. These test cases cover the lower and upper boundaries, as well as values just outside the boundaries to ensure that the system handles them correctly.Rate this question:

Which is not a Component testing
- A.
Check the memory leaks
- B.
Check the robustness
- C.
Check the branch coverage
- D.
Check the decision tables
Correct Answer
D. Check the decision tablesExplanation
Component testing is a type of software testing that focuses on the individual components or modules of a system. It is performed to ensure that each component functions correctly and meets its specified requirements. In this context, checking the decision tables is not considered a component testing activity. Decision tables are used for testing the logic and decision-making capabilities of a system, which is more closely associated with integration or system testing rather than component testing.Rate this question:

PDCA, which stands for Plan, Do, Check, Act, is a widely recognized management method used to improve processes and achieve continuous improvement. The process begins with planning, where goals and objectives are set. Then, the plan is executed through implementation or doing. Next, the results are checked and evaluated against the goals set in the planning phase. Finally, based on the evaluation, necessary adjustments and corrective actions are taken to improve the process, leading to continuous improvement. This cycle is repeated to ensure ongoing improvement and optimization of processes.Rate this question:

Contract and regulation testing is a part of
- A.
System testing
- B.
Acceptance testing
- C.
Integration testing
- D.
Smoke testing
Correct Answer
B. Acceptance testingExplanation
Acceptance testing is a type of testing that evaluates whether a system meets the requirements and specifications set by the stakeholders. Contract and regulation testing ensures that the system complies with legal and regulatory requirements. Since acceptance testing focuses on verifying if the system is acceptable for delivery to the stakeholders, it is the most appropriate category for contract and regulation testing. System testing, integration testing, and smoke testing do not specifically address the compliance aspect of the system.Rate this question:
