The following chart represents metrics related to testing indicates what is represented by lines A,B and axis X,Y Select one:
-
XTime, YCost,ACost of test(per week), BCost of finding a single bug(per week)
-
XTime, YNumber of defects, ANumber of open defects, BNumber of closed defects
-
XTime, YCount, ATotal number of executed tests, BNumber of open bugs.
-
XTime, YPercent, A% of functional tests in the test suite, B% of nonfunctional tests in the test suite
Correct Answer
A. XTime, YCount, ATotal number of executed tests, BNumber of open bugs.Explanation
The chart represents the relationship between time (X-axis) and count (Y-axis). Line A represents the total number of executed tests, while line B represents the number of open bugs. This indicates that the chart is showing the correlation between the time spent on testing and the number of tests executed, as well as the number of bugs that are still open.Rate this question:

Consider the following pseudo code, Integer k; If (k > 1 && k < 30), Then .... End if, Which of the following sets of test input values is the result of correct boundary value analysis? Select one:
-
3, 2,1,0, 30, 31, 32, 33
-
1, 2, 29, 30
-
0, 1, 30, 31
-
1,0,1,2,29,30,31
Correct Answer
A. 1, 2, 29, 30Explanation
The correct boundary value analysis for the given pseudo code would include testing the lower and upper boundaries of the condition. In this case, the condition is (k > 1 && k < 30). Therefore, we need to test values that are just above and below the boundaries. The set of test input values 1, 2, 29, and 30 covers these boundaries and ensures that the condition is tested correctly.Rate this question:

In the fundamental test process, what does primarily entail the test analysis and design activity? Select one:
-
The transformation of the test objectives in testing conditions and tangible test cases
-
The continues comparison between current progress and the test plan, in order to identify deviations
-
The test ability evaluation of the test basis and test objects and the rootcause analysis
-
The data collection on the completed test activities, in order to consolidate experience, testware, facts and figures

Which of the following statement is true? Select one:
-
Experience based testing is best used in integration testing.
-
Black box testing is equivalent to equivalence partitioning
-
Experience based testing should be applied after systematic test methods have been used.
-
White box testing is equally useful for low level and high level testing
Correct Answer
A. Experience based testing should be applied after systematic test methods have been used.Explanation
Experience based testing should be applied after systematic test methods have been used because systematic test methods provide a structured approach to testing, ensuring that all necessary test cases are covered. Once systematic test methods have been exhausted, experience based testing can be used to complement and enhance the testing process. This type of testing relies on the tester's knowledge, skills, and intuition to identify potential issues that may not have been covered by the systematic approach. By combining both systematic and experience based testing, the overall effectiveness and coverage of the testing process can be improved.Rate this question:
