- A.
1 test for statement coverage, 3 for branch coverage
- B.
2 tests for statement coverage, 2 for branch coverage
- C.
2 tests for statement coverage. 3 for branch coverage
- D.
3 tests for statement coverage, 3 for branch coverage
- E.
3 tests for statement coverage, 2 for branch coverage
Correct Answer
B. 2 tests for statement coverage, 2 for branch coverageExplanation
The given code contains two branches: one for the "IF" statement and one for the "ELSE" statement. To achieve branch coverage, we need to test both branches. Since there are only two branches, we need two tests for branch coverage. Additionally, the code contains four statements: the "IF" statement, the "ELSE" statement, the "Read D" statement, and the "Print 'Error'" statement. To achieve statement coverage, we need to test all four statements. Therefore, we need two tests for statement coverage and two tests for branch coverage.Rate this question:

What is the MAIN benefit of designing tests early in the life cycle?
- A.
It is cheaper than designing tests during the test phases.
- B.
It helps prevent defects from being introduced into the code.
- C.
Tests designed early are more effective than tests designed later.
- D.
It saves time during the testing phases when testers are busy.
Correct Answer
B. It helps prevent defects from being introduced into the code.Explanation
Designing tests early in the life cycle helps prevent defects from being introduced into the code. By identifying and addressing potential issues at an early stage, the development team can ensure that the code is more robust and reliable. This can save time and resources that would otherwise be spent on fixing and debugging later on. Additionally, early testing allows for better understanding of the requirements and specifications, leading to more effective test design and coverage.Rate this question:

What is the KEY difference between preventative and reactive approaches to testing?
- A.
Preventative tests and reactive tests are designed as early as possible.
- B.
Preventative tests are designed early; reactive tests are designed after the software has been produced.
- C.
Preventative testing is always analytical; reactive testing is always heuristic.
- D.
Preventative tests are designed after the software has been produced; reactive tests are designed early in response to review comments.
Correct Answer
B. Preventative tests are designed early; reactive tests are designed after the software has been produced.Explanation
The key difference between preventative and reactive approaches to testing is the timing of when the tests are designed. Preventative tests are designed early, before the software has been produced, with the aim of preventing defects and issues from occurring. On the other hand, reactive tests are designed after the software has been produced, in response to identified defects or issues. This difference in timing allows preventative testing to be proactive and proactive, while reactive testing is more responsive and reactive to problems that have already occurred.Rate this question:

- D.
1
Correct Answer
B. 4Explanation
The given code fragment contains two decision points: the first decision point is the condition "width > length" and the second decision point is the condition "height > width". To achieve 100% decision coverage, we need to test both possible outcomes of each decision point. Therefore, we need to test the following combinations:
1. width > length and height > width
2. width > length and heightRate this question:

A thermometer measures temperature in whole degrees only. If the temperature falls below 18 degrees, the heating is switched off. It is switched on again when the temperature reaches 21 degrees. What are the best values in degrees to cover all equivalence partitions?
- A.
15, 19 and 25.
- B.
17, 18 and19.
- C.
18, 20 and22.
- D.
16, 26 and 32.
Correct Answer
A. 15, 19 and 25.Explanation
The best values in degrees to cover all equivalence partitions are 15, 19, and 25. This is because the thermometer measures temperature in whole degrees only, and the heating is switched off when the temperature falls below 18 degrees and switched on again when it reaches 21 degrees. Therefore, the values of 15 and 25 cover the range outside of the heating limits, and the value of 19 covers the range between the heating limits.Rate this question:

Reviews, static analysis and dynamic testing have the same objective
- A.
Identifying defects.
- B.
Fixing defects.
- C.
A and B
- D.
None of the above
Correct Answer
A. Identifying defects.Explanation
Reviews, static analysis, and dynamic testing all aim to identify defects in a system or software. Reviews involve examining the code or documentation to find any potential issues. Static analysis involves analyzing the code without executing it to identify defects. Dynamic testing involves executing the code to uncover defects during runtime. Therefore, all three approaches have the common objective of identifying defects.Rate this question:
