The following chart plots the cumulative number of defects opened against the cumulative number of defects closed during system testing of a software product.Which of the following statements is true?
Which one of the following metrics to be produced needs traceability between the test cases and each item in a proper test basis?
After the presentation, you are asked to explain the chart.Assume you have applied a full risk-based testing strategy.Which of the following answers would you expect to best describe the pie chart?
You are managing the system testing for a SOA based system. The integrated system consists of several subsystems: a SOA middleware a CRM (Customer Relationship Management) system a BRM (Billing and Revenue Management) system a SMS (Subscriber Management System) system and you performed a risk analysis based on these subsystems.At the end of the scheduled period for test execution you produce a first classical report based on the traditional metrics of testing. Test pass/fail status and bug status (open/resolved) That table provides you a distorted picture of the quality risk, because there is no indication of the risk level of the failed tests, the tests not run, or the open bugs. Thus, you produce the following table to solve this distortion issue:In the table above, where you have introduced the concept of risk weighting, the highest risk test or bug report has a score of 1, while the lowest risk test or bug report has a score of 0.04.Which of the following subsystems, based on the risk scores of the table, is most risky?
For which of the following activities would the costs be classified as a cost of detection?
Assume you have some data related to confirmation testing during system testing of a past project.In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three times and no bug reports have been opened more than three times.You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 person-hours.Which of the following statements correctly describe the value of these confirmatory testing activities based on cost of quality?
