D. Having the developer write tests for his own codeExplanation
The testing approach with the least independence is having the developer write tests for his own code. This is because the developer may have biases and may not be able to objectively test their own code. There is a higher chance of overlooking errors or not testing all possible scenarios. Having another developer on the same team write the tests or having a tester on an independent team write the tests provides more independence and helps in identifying issues that the developer may have missed. Having the users write the tests may not be feasible or practical in all cases, but it can provide valuable insights from a user's perspective.Rate this question:

Which of the following are correct tasks during ‘Test analysis and design’? I. Designing and prioritizing test cases II.Identifying any required infrastructure and tools III.Reviewing the test basis. IV. Creating test data and preparing test harmness V. Writing automated test scripts.
- A.
I,II,III
- B.
I,II,III,IV
- C.
I,II
- D.
II,III,IV,V
Correct Answer
B. I,II,III,IVExplanation
During the 'Test analysis and design' phase, the correct tasks include designing and prioritizing test cases, identifying any required infrastructure and tools, reviewing the test basis, and creating test data and preparing test harness. These tasks are essential for ensuring that the testing process is well-planned and efficient. Additionally, writing automated test scripts can also be a part of this phase as it helps in automating the testing process and improving test coverage. Therefore, the correct answer is I, II, III, IV.Rate this question:

The Pesticide Paradox means:
- A.
Every method you use to find bugs is limited by your knowledge and experience
- B.
Every method you use to find bugs works according to the 80-20 rule: 80 percent of the bugs will be found in 20 percent of the code
- C.
Every method you use to find bugs finds fewer than the methods you used before
- D.
Every method you use to find bugs leaves other bugs against which those tests are ineffective
Correct Answer
D. Every method you use to find bugs leaves other bugs against which those tests are ineffectiveExplanation
The Pesticide Paradox means that every method used to find bugs will inevitably leave behind other bugs that are not detected by those tests. This is because as bugs are fixed, new bugs are introduced or existing bugs are overlooked. Therefore, no matter how thorough or comprehensive the bug-finding methods are, there will always be bugs that remain undetected and are not effectively targeted by the tests.Rate this question:

In If a test suite is executed and anomalies (unexpected results) are found, it could mean: 1.No further investigation is needed 2 The test cases were poorly designed 3 Software defects are in the system 4 The tests were executed improperly
- A.
1 and 2 are true; 3 and 4 are false
- B.
2 and 3 are true; 1 and 4 are false
- C.
2, 3, and 4 are true; 1 is false
- D.
1, 2, and 3 are true; 4 is false
Correct Answer
C. 2, 3, and 4 are true; 1 is falseExplanation
If anomalies (unexpected results) are found during the execution of a test suite, it suggests that there are software defects in the system (option 3). This means that there are issues or bugs in the software being tested. Additionally, it also indicates that the test cases were poorly designed (option 2), as they failed to identify these anomalies. Lastly, it suggests that the tests were executed improperly (option 4), meaning that there may have been mistakes or errors in the way the tests were conducted. However, no further investigation is needed (option 1) because the anomalies already indicate the presence of software defects. Therefore, options 2, 3, and 4 are true, while option 1 is false.Rate this question:

In software testing, what is the primary purpose of boundary value analysis?
- A.
To identify the maximum number of test cases
- B.
To identify the values that are not included in the test cases
- C.
To test the behavior of the software at or near its limits
- D.
To determine the average value for test inputs
Correct Answer
C. To test the behavior of the software at or near its limitsExplanation
Boundary value analysis is a software testing technique used to assess the software's behavior at or near its boundary values or limits. This is important because errors often occur at the edges of input ranges or limits. It helps in identifying potential issues related to boundary conditions, which can lead to more effective testing.Rate this question:
