Which of the following would you expect to be most likely an example of a motivating factor for testers?
Number of correct responses: 1

• A.The testers are asked to perform, in parallel with their testing tasks, other tasks unrelated to their testing responsibilities
• B.The same regressions tests are executed manually by the same testers, for every product release, without any progression in content
• C.The resources allocated for the testing activities are not sufficient and don't allow the testers to contribute to the quality of the product
• D.The testers contribution to the quality of the software products developed from an organization is recognized with increased responsibilities

You are performing a quality risk analysis for a CSCI (Computer Software Configuration Item) used to implement a
CBIT (Continuous Built-In Test) module of a safety-critical system.
During the quality risk analysis you are trying to identify the ways in which failures of the CBIT module can occur, for each of them trying to determine the potential causes and likely effects, and the risk level (calculated as the product of three factors: severity, occurrence and detection).
Which of the following risk analysis techniques are you working with?
Number of correct responses: 1

• A.Cost of Exposure
• B.Wide Band Delphi
• C.Failure Mode and Effect Analysis
• D.A lightweight product risk analysis technique

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 open-source 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?
Number of correct responses: 3
(2 credits out of 3 credits correct, 1 credit point)

• A.Is the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?
• B.What are the costs to qualify the tool as a verification tool under the DO-178B?
• C.Does the tool support all the types of code coverage required from the three levels A, B, C of the DO-178B standard?
• D.Is the installation procedure of the tool easy?
• E.Does the tool have a good general usability?
• F.Does the tool require a system with more than 4GB of RAM memory?

The following is the unique "critical" quality risk item that has been identified:
CR-RSK-1. The GUI of the application might accept non-integer values for the input field designed to get the number of bottles from the user
Test analysis for system testing has just begun and the following test conditions have been identified:
TC-SEL-2. Test the selection of the package sizes
TC-SEL-4. Test wrong numbers of bottles for an order
TC-CR-RSK-1. Test the accepted values from the input field designed to get the number of bottles from the user
Assume that you have used traceability to determine the logical test cases that cover all the requirements and the single risk item identified in that scenario.
Which of the following is a positive logical test that is complete and correct, and covers the REQ-SEL-4 requirement?
Number of correct responses: 1

• A.Select a 6-bottles package, then try to insert 7 bottles; verify that no error messages are displayed
• B.Select a 6-bottles package, then try to insert 7 bottles; verify that the "Invalid number of bottles" message is displayed
• C.Select a 6-bottles package, then try to insert 5 bottles; verify that no error messages are displayed
• D.Select a 6-bottles package, then try to insert 7 bottles

Which of the following information would you expect to be the most useful to perform a defect clustering analysis?
Number of correct responses: 1

• A.The trend in the lag time from defect reporting to resolution
• B.The lifecycle phase in which the defect has been introduced
• C.The defect component information
• D.The defect removal efficiency information
