Which of the following answers describes a factor that may reduce the effort spent when using distributed test teams without negatively affecting system quality?
K2 1 credit

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?
K3 2 credits
A. Produce a single master test plan that covers in detail all four levels, describing the particular activities for all test levels
B. Produce a master test plan that covers three levels (component, integration, system test) and a separate acceptance test plan
C. Produce a master test plan describing the relationship between the four levels, and four separate detailed level test plans, one for each level
D. Produce four separate detailed level test plans, one for each level, without a master test plan
Which of the following statements describing how identified product quality risks should be mitigated and managed, is true?
K2 1 credit A. The extent of re-testing and regression testing activities should be based on the risk level
B. The identification of new risks, the re-assessment of the level of existing risks and the evaluation of the effectiveness of risk mitigation activities should only occur at the very beginning of a project
C. Risk mitigation of product quality risks can be effective only after starting test execution
D. The priority of the development and execution of tests should not be based on the risk level but only on the likelihood
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 about management of product quality risks in mature organizations with respect to the lifecycle, is true?
K2 1 credit
A. Mature organizations address product quality risks associated to non-functional characteristics only during the system test phase
B. Mature organizations are aware that the contribution of testing to analysis of product quality risks is very important. The analysis should occur throughout the entire lifecycle
C. Mature organizations don't waste time identifying the sources of risks. They only focus on identifying product quality risks
D. Mature organizations are aware that risk management of product quality risks only occurs during testing
Which one of the following metrics to be produced needs traceability between the test cases and each item in a proper test basis?
K2 1 credit
A. Requirements coverage
B. Trends in the lag time from defect reporting to resolution
C. Mean time between failures for the system
D. Cumulative number of reported defects versus cumulative number of resolved defects
Consider the following test strategies:
I. Consultative test strategy
II. Reactive test strategy
III. Analytical test strategy
IV. Process-compliant test strategy
Consider also the following examples of test activities:
1.
Prioritize the test cases, based on the results of a FMEA analysis, to ensure early
coverage of the most important areas and discovery of the most important defects during test execution
2.
Execute usability testing driven by the guidance of a sample of users (external to the test team)
3.
Perform exploratory testing sessions throughout the system test phase
4.
On an Agile project, execute tests that cover the test conditions identified for each user story of a feature
planned for an iteration
Which of the following correctly matches each test strategy with an appropriate example? K2 1 credit
A. I-2; II-3; III-4; IV-1
B. I-3; II-2; III-1; IV-4
C. I-1; II-2; III-3; IV-4
D. I-2; II-3; III-1; IV-4
Assume you are managing the system testing phase of a project.
The system test execution period is scheduled to twenty weeks.
All tests are manual tests. You are following a risk-driven test approach.
During the last staff meeting the project manager tells you new deadlines that will not allow completion of
all the system tests.
Which of the following would you expect to be the best way to respond to this situation?
K2 1 credit
A. Prioritize executing the tests for the highest product risks and track these risks
B. Remove testers from your test team, so that they can be assigned to other projects
C. Automate all remaining tests
D. No action is needed, test as much as possible in the remaining time period
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
Assume you are currently working on a project developing a system where functional requirements are
very well specified. Unfortunately non-functional requirements do almost not exist.
You are the Test Manager. You have to choose a technique for test selection that allows testing of nonfunctional characteristics, especially reliability.
Which of the following techniques for test selection do you expect being most useful in this scenario? K2 1 credit
A. A model-based technique based on the creation of operational profiles
B. Ambiguity reviews
C. Test condition analysis D. Cause-effect graphing
