D. Deliver an automated regression test suite, used during the system test phase of a software product released into production, to the team responsible for maintenance testing
You can count on well-written requirements, but you can't count on an adequate contribution of the stakeholders to the quality risk analysis. You have to mitigate the insufficient contribution of the stakeholders because the risk-based testing approach shall minimize the product risks. Your test team has one expert tester in security testing.
Which of the following test activities would you expect to be the less important in this context?
K4 3 credits
A. Extract from the defect tracking system of the previous project all the security defects and failures, and classify them to support design and execution of specific tests
B. Automate all functional and non-functional system tests
C. Apply systematic and exploratory testing for integration and system test
D. Perform exploratory testing sessions with adequate charters covering security aspects

Assume you have some data related to confirmation testing during system testing of a past project.
In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three
times and no bug reports have been opened more than three times.
You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 person-hours.
Which of the following statements correctly describe the value of these confirmatory testing activities based
on cost of quality? K3 2 credits
A. 300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure
B. 340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of external failure
C. 340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure
D. 300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of detection
Consider an agile team adopting Extreme Programming (XP) with five developers and one tester without
any coding experience.
To which of the following activities would you expect the tester will contribute most?
K2 1 credit
A. Developing unit tests
B. Executing unit tests
C. Planning and executing tests during the integration test phase to detect interface defects
D. Supporting the customer in the execution of acceptance testing
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?
K2 1 credit
A. A lightweight product risk analysis technique
B. Failure Mode and Effect Analysis
C. Wide Band Delphi
D. Cost of Exposure
Which of the following statements best describes an appropriate approach for managing exploratory testing?
Number of correct responses: 1
K2 1 credit
A. Define very detailed mission statements, which allow testing work to be broken into sessions of up to 10 minutes duration in which testing is guided by these mission statements
B. Break the testing work in 30 to 120 minutes sessions and use properly defined mission statements consisting of two or three sentences to guide testing during these sessions
C. Define very generic charters to drive exploratory testing sessions of 2 days where testers are completely free to decide what to test
D. Exploratory testing should not be managed because such testing is inherently unmanageable and not measurable
After the presentation, you are asked to explain the chart. Assume you have applied a full risk-based testing strategy.
Which of the following answers would you expect to best describe the pie chart?
K4 3 credits
A. All the risk items have been covered with tests. No more risk items remain to test
B. According to the full risk-based testing strategy applied, it is very likely that the highest- risk items, tests and bugs remain in the blue and red areas. Therefore, it is very risky to release the application
C. Only the lowest-risk items, tests and bugs should remain in the blue and red areas. Therefore the application can be released at any time subject to management of the items identified in those areas
D. 97 percent of the risk items has been tested. No open bugs or test failures remain. Only 3 percent of risk items remains to be covered by the remaining test
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?
K4 3 credits (2 credits out of 3 credits correct, 1 credit point)
A. Does the tool support all the types of code coverage required from the three levels A, B, C of the DO178B standard?
B. Does the tool have a good general usability?
C. What are the costs to qualify the tool as a verification tool under the DO-178B?
D. Is the installation procedure of the tool easy?
E. Does the tool require a system with more than 4GB of RAM memory?
F. Is the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?
Which of the following would you expect to be most likely an example of a motivating factor for testers? K2 1 credit
A. The resources allocated for the testing activities are not sufficient and don't allow the testers to contribute to the quality of the product
B. The testers contribution to the quality of the software products developed from an organization is recognized with increased responsibilities
C. The same regressions tests are executed manually by the same testers, for every product release, without any progression in content
D. The testers are asked to perform, in parallel with their testing tasks, other tasks unrelated to their testing responsibilities
