Assume you are the Test Manager in charge of independent testing for avionics applications. You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item):

- a BOOT-X CSCI that must be certified at level B of the DO-178B standard

- a DIAG-X CSCI that must be certified at level C of the DO-178B standard

- a DRIV-X CSCI that must be certified at level A of the DO-178B standard

These are three different software modules written in C language to run on a specific hardware platform.

You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. This tool must be qualified as a verification tool under DO-178B.

Since there are significant budget constraints to purchase this tool, you are evaluating an opensource tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler).

The source code of the tool is available.

Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B.

Which of the following are the three main concerns related to that open-source tool selection?

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

2. Unexpected timing of components arrival

3. Stability of the integration test team (no turnover)

4. Many and geographically distributed sub-teams

Which of the following statements is true?

The main objectives the senior management team wants to achieve are:

- to reduce the costs associated with dynamic testing

- to use reviews to ensure that the project is on course for success and following the plan

- to use reviews as a well-documented and effective bug-removal activity following a formal process with well-defined roles

- to determine the effectiveness of reviews in terms of phase containment

- to improve phase containment effectiveness

Which of the following answers would you expect to describe the best way to achieve these objectives?

An agile development team decides to hire a tester who has always worked.

- in independent test teams, reporting the problems found in a defect tracking system

- in safety-critical projects, with a stronger focus on the quality of the product than on time and budget. This agile team is focused on short-term goals to get the product released on time and within budget. Which of the following answers would you expect to be most likely true in this scenario?

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? K4 3 credits
