The previous release of an in-house invoicing application was live for 6 months before beingreplaced by a later release.

• Before it went live, €1,500 had been spent on defect prevention and a further €4,500 had been spent on writing and running tests; these tests found 80 defects and the average cost of dealing with these was €50 each.

• By the time that it was replaced, defect reports from live running showed that pre-release testing had found only 80% of the defects that were present; the average cost of dealing with the defects that went live was 12 times that of the internal failures.

Which statement is TRUE?

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?
