You are the Test Manager of a project that adopts a V-model with four formal levels of testing: unit, integration, system and acceptance testing.
On this project reviews have been conducted for each development phase prior to testing, which is to say that reviews of requirements, functional specification, high-level design, low-level design and code have been performed prior to testing.
Assume that no requirements defects have been reported after the release of the product.

Test Management
You are the Test Manager of a new project that will have three formal levels of testing: unit, integration and system testing. The testing strategy you decide to adopt a blend of risk-based testing and reactive testing strategies.

Number of correct responses: 1
K21 credit
A. Your test team executes system tests under the guidance of a sample of users throughout the system test phase
B. Your test team executes scripted tests designed and implemented before the execution of the system test phase, to cover the identified product risks. It also performs exploratory testing sessions throughout the system test phase
C. Your test team autonomously performs some exploratory testing sessions and, at the very end of the system testing phase, it also executes more system tests under the guidance of a sample of users
D. Your test team executes exploratory tests following a session-based test management approach throughout the system test phase
正解：B

質問 4：
You are not confident with the assessment of the risk level and you suspect that it will be possible to find high-priority bugs in low-risk areas.
Furthermore the period for test execution is very short. Your goal is to test all the product risks in a risk-based way, while assuring that each product risk gets at least some amount of testing.

Which of the following answers describes the best test execution schedule in this scenario?
Number of correct responses: 1

C. T1, T3, T5, T7, T9, T2, T4, T6, T8, T10
D. T10, T9, T8, T7, T6, T5, T4, T3, T2, T1

質問 5：
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
K32 credits
A. Select a 6-bottles package, then try to insert 7 bottles
B. Select a 6-bottles package, then try to insert 7 bottles; verify that no error messages are displayed
C. Select a 6-bottles package, then try to insert 7 bottles; verify that the "Invalid number of bottles" message is displayed
D. Select a 6-bottles package, then try to insert 5 bottles; verify that no error messages are displayed

Testing Process
Consider an information system of a Pay-Tv company based on a SOA architecture.
The integrated system currently consists of three core systems:
- a CRM (Customer Relationship Management) system
- a BRM (Billing and Revenue Management) system
- a CAS (Conditional Access System) system
all of them communicating with SOA Middleware.
You have been asked to manage the testing activities for the integration of two additional off-the-shelf systems from two different vendors: a SMS (Short Message Service) server and an IVR (Interactive Voice Response) system.
Assume that there is a high likelihood that the two off-the-shelf systems will be low-quality and that you have a clear proof that the testing performed by the two vendors on their systems has been unsystematic and unprofessional. This obviously leads to higher quality risk for the overall integrated system.
You are the Test Manager of this project. Your main goal is to plan for testing activities to mitigate this risk.
Which of the following answers best describes the test activities (assuming it is possible to perform all of them) you should plan for?
Number of correct responses: 1
K43 credits
A. You should plan for adequate re-testing of both the systems followed by a system integration test and an end-to-end test of the overall integrated system
B. You should plan for two levels: a system integration test and an end-to-end test of the overall integrated system
C. You should directly plan for a single end-to-end test focused on end-to-end tests of the overall integrated system without an acceptance test of the two off-the-shelf systems
D. You should plan for an informal and minimal acceptance test of the two off-the-shelf systems and then a single end-to-end test of the overall integrated system
正解：A

質問 7：
Most managers in your company consider the efforts of your test team valuable, while others see comprehensive testing as an unnecessary cost overhead to the SDLC.

A. Develop metrics that illustrate planned and actual testing hours.
B. Demonstrate the role QA has in similar size organizations.
C. Determine the cost of external failures.
D. Review the Test Plan with the management team.

Test Management
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?
Number of correct responses: 1
K21 credit
A. Automate all remaining tests
B. No action is needed, test as much as possible in the remaining time period
C. Remove testers from your test team, so that they can be assigned to other projects
D. Prioritize executing the tests for the highest product risks and track these risks
正解：D

質問 9：
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?
Number of correct responses: 1
K33 credits
A. The defect management process
B. The requirements review
C. The quality risk analysis process
D. The system design and architecture design reviews
正解：A
