A chart showing the trend in the lag time from defect reporting to resolution during system testing is also available. The chart shows that the daily closure period is consistently and significantly above the rolling closure period for a long period of the system testing phase. Almost all defects found during system testing have been related to the system as a whole, not related to single units or integrations issues. Almost all quality risks have been addressed during the unit and integration testing phase and no residual quality risks were present in the integrated system. This has been confirmed by exploratory testing sessions performed during system testing, targeted at finding defects in these quality risk areas. Based on the given information only, which one of the following areas would you expect to be considered more in the retrospective meeting in order to be improved?

You are estimating the effort for the integration testing activities of a new project. Consider the following factors, which can affect that estimation:
Availability of re-usable test systems and documentation from previous, similar projects
Unexpected timing of components arrival
Stability of the integration test team (no turnover)
Many and geographically distributed sub-teams
Which of the following statements is true?

Based on the historical data of 5 past and similar projects, you have calculated these average numbers of defects detected in system testing.
- For each 10000 LOC (lines of code), 200 defects
- For each person-month of development team effort, 49 defects
You want to use this information to perform estimation for a new project.
The project manager tells you that he/she has estimated 20000 new LOC for this new project.
Four developers work for four months on this project before system testing.
During system testing, 797 defects are discovered.
Assume that the system test of this new project is using the same amount of work as spent in the past projects.
Based on this information only, which of the following statement is certainly true about this project? K3 3 credits
You are the Test Manager of a new project aimed at developing a software system that must be certified at level B of the DO-178B standard. The project will follow a V-Model software development life cycle and it will have four formal levels of testing: component, integration, system and acceptance testing.
You must produce the test plan documentation for this project by providing an adequate coordination across the four levels of testing in order to assure audit ability.
Which of the following answers would you expect to best describe how to organize the test plan?
