Question 414
|
The test suite (set of test input) used to perform unit testing on module could cover 70% of the code. What is the reliability of the module if the probability of success is 0.95 during testing?
|
0.665 to 0.95
|
|
|
At the most 0.665
|
|
|
At the most 0.95
|
|
|
At least 0.665

Question 414 Explanation:
Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment.
From the given question the module code covers 70% of the entire code, so we need to check with reliability for that module only.
Reliability = percentage of code coverage * probability of success = 0.7 * 0.95 = 0.665.
Probability of success is at most 0.665 %
From the given question the module code covers 70% of the entire code, so we need to check with reliability for that module only.
Reliability = percentage of code coverage * probability of success = 0.7 * 0.95 = 0.665.
Probability of success is at most 0.665 %
