You are a Test Manager at a company that develops mobile phone applications. Based on historical data in your company, you have calculated the following average metrics for system testing:
* for each 100 LOC (Lines Of Code). 4 test cases are executed
* each test case takes on average 15 minutes to execute and check
* for each 1000 LOC, 5 defects are found
You have used this information to create an estimate for the system testing of a new mobile phone application being developed to submit gas and electricity readings.
The application delivered for system testing has 50.000 lines of code. At the end of system testing, 250 defects are discovered.
Assume that:
* the system test of the new mobile phone application will require the same amount of effort as previous applications
* defect density = number of defects/1000 LOC
* no new tools or processes have been introduced to the test team
Based only on the given information, which one of the following statements is true about this new mobile phone application?

Assume that you are working for a company that has maintained and tested a car parking permit system for many years. The system holds the name and address of permit holders and automatically writes to the permit holder with a form to renew or cancel their permit each year.
The test plan states the following:
"since the system is considered a stable system. Boundary Value Analysis is the only test case design technique that needs to be applied during testing" Consider the following change that was detailed in the Requirements Specification for a replacement to an existing parameter held within the system;
* The specified renewal date for each permit must be not be after 31 st January 2020. Which one of the following is a valid test condition that satisfies both the requirement and the test plan?

You are a newly appointed Test Manager in an organisation that has no separate test team, no formal testing process and testing is considered to be, at best, ad-hoc in approach. The IT director is keen to introduce improvement across all areas of the organisation, not just testing. This is so that the current level of maturity can be assessed and roadmaps outlined for improving processes in a staged way. He has asked you to recommend a test process improvement model and you have suggested TMMi.

You are planning the testing for an emergency product update required to correct a serious security issue and to improve system maintainability of a key product in your company's catalogue. It has been estimated that the historical cost to the company for the security issue in this system has been $375,000.
In the last year a total of 10 reported "live' incidents were reported, resulting in a total external failure cost of S110.000 to correct.
The cost of prevention for this project has been estimated as $78,500 and from the development you have learned that the average cost of detection was $1,250 and the average cost of internal failure was $7,450 Which one of the following statements about cost of quality is TRUE? SELECT ONE OPTION
