Mr. Test has been testing software applications on mobile devices for a period of 5 years. He has a wealth of experience in testing mobile applications and achieves better results in a shorter time than others. over several months, Mr. Test did not modify the existing automated test cases and did not create any new test cases. this leads to fewer and fewer defects being found by executing the tests. what principle of testing did Mr. Test not observe? a) Testing depends on the environment b) Exhaustive testing is not possible c) Repeating of the same tests will not find new defects d) Defects cluster together - C In what way can testing be part of Quality Assurance? a) It ensures that requirements are detailed enough b) Testing reduces the risk of poor software quality c) It ensures that standards in the organization are followed d) It measures the quality of software in terms of number of executed test cases - B Which of the following activities is part of the main activity "test analysis" in the test process? a) Identifying any required infrastructure and tools b) Creating test suites from test scripts c) Analyzing lessons learned for process improvement d) Evaluating the test basis for testability - D Match the following test work products (1-4) with the right description (A-D)

The work product to be reviewed is a description of the in-house document creation process. The aim of the description is to present the work distribution between the different roles involved in the process in a way that can be clearly understood by everyone. You will be invited to a checklist-based review. The checklist will also be sent to you. It includes the following points: i. Is the person who performs the activity clearly identified for each activity? ii. Are the entry criteria clearly defined for each activity? iii. Are the exit criteria clearly defined for each activity? iv. Are the supporting roles and their scope of work clearly defined for each activity? In the following we show an exerpt of the work result to be reviewed, for which you should use the checklist above: "After checking the customer documentation for completeness and correctness, the software architect cr - D
