‘Defect Density’ calculated in terms of
-
The number of defects identified in a component or system divided by the size of the component or the system
-
The number of defects found by a test phase divided by the number found by that test phase and any other means after wards
-
The number of defects identified in the component or system divided by the number of defects found by a test phase
-
The number of defects found by a test phase divided by the number found by the size of the system
Correct Answer
A. The number of defects identified in a component or system divided by the size of the component or the systemExplanation
Defect density is calculated by dividing the number of defects identified in a component or system by the size of the component or system. This calculation helps to measure the quality of the component or system by providing a ratio of defects to the overall size. A higher defect density indicates a higher number of defects per unit of size, which suggests a lower quality product. Conversely, a lower defect density indicates a lower number of defects per unit of size, indicating a higher quality product.Rate this question:

‘Be bugging’ is known as
-
Preventing the defects by inspection
-
Fixing the defects by debugging
-
Adding known defects by seeding
-
A process of fixing the defects by tester
Correct Answer
A. Adding known defects by seedingExplanation
Adding known defects by seeding is a term used in software testing where testers intentionally introduce known defects into a system or application. This is done to assess the effectiveness of the testing process and to identify any potential vulnerabilities or weaknesses in the system. By intentionally adding defects, testers can evaluate how well the system detects and handles these issues, allowing for improvements to be made before the software is released to the end users.Rate this question:

When testing a grade calculation system, a tester determines that all scores from 90 to 100 will yield agrade of A, but scores below 90 will not. This analysis is known as:
-
Equivalence partitioning
-
Boundary value analysis
-
Decision table
-
Hybrid analysis
Correct Answer
A. Equivalence partitioningExplanation
Equivalence partitioning is a testing technique where the input data is divided into different partitions or groups that are expected to exhibit similar behavior. In this case, the tester has identified two partitions - scores from 90 to 100 and scores below 90. The behavior within each partition is expected to be the same, i.e., scores from 90 to 100 will yield a grade of A, while scores below 90 will not. This analysis helps in selecting representative test cases from each partition to ensure adequate test coverage.Rate this question:

Find the Min number of tests to ensure that each statement is executed at least once
-
5
-
6
-
4
-
8
Correct Answer
A. 6Explanation
To ensure that each statement is executed at least once, we need to find the minimum number of tests. One way to do this is by using a loop that iterates through each statement until all of them have been executed. In this case, since there are 4 statements, we need at least 4 tests to cover all of them. However, the answer given is 6, which means that there might be additional conditions or dependencies between the statements that require extra tests to ensure their execution. Without further information, it is not possible to determine the exact reason for needing 6 tests.Rate this question:
