質問 1：
Test Analysts are doing test design for a change request to an insurance comparison system. The system provides car insurance quotations, using data input by the user.
The change request states:-
Drivers must be aged between 17 to 85 years inclusive to qualify for insurance comparison.
The following Test Conditions have been identified:
1 Driver's age is less than the minimum
2. Driver's age is within the valid range
3. Driver's age is more than the maximum
The Test Strategy states the test techniques to be used include Equivalence Partitioning and Boundary Value Analysis. Using the Test Conditions and techniques stated in the Test Strategy, the following Test Cases have been created.

As the Test Manager you are reviewing these Test Cases for traceability to the Test Conditions and to ensure that the change request will be adequately tested in accordance with the Test Strategy.
Which of the following statements is FALSE? SELECT ONE OPTION
A. The Test Conditions have fully covered the change request.
B. The traceability of the Test Cases to Test Conditions is clear.
C. The change request requirements have been clearly stated.
D. The Test Cases fully test the Test Conditions in relation to the Test Strategy.
正解：D

質問 3：
You are Test Manager on a new project and have estimated the test effort to be 500 days, assuming that you will find no more than 50 defects and 5 test iterations being required. The project manager has said the estimate is too high. Which of the following options could enable you to reduce this estimate?
SELECT ONE OPTION
A. Assign more test analysts to the test execution phase.
B. Increase the regression test coverage.
C. Allow more time for the developers to fix the defects found.
D. Agree an increase in the Unit test coverage before the code is delivered to your test team.
正解：D

質問 4：
You are the Test Manager on a new project. The schedule is aggressive and will require the team to work at peak efficiency. The requirements are not well defined yet, but it is clear that the project will be using new technologies. To help the developers meet the development schedule, an offshore group will be added to the development team.
At this time there is not enough budget to add more testing resources. The project stakeholders are very concerned about the quality of delivered product and will be watching the project closely, particularly during the testing cycles. The exit criteria from the system test level require no open high priority
/severity defects, 100% pass rate for all test cases covering risks that are classified as
"high" or "very high", 90% pass rate for all "medium" risks and 50% pass rate for all "low" and "very low" risks.
Given this information, which lifecycle model should you recommend? [3]
A. Iterative/incremental
B. V-model
C. Spiral
D. Waterfall

質問 5：
You are a Test Manager at a company that develops mobile phone applications. Based on historical data in your company, you have calculated the following average metrics for system testing:
* for each 100 LOC (Lines Of Code). 4 test cases are executed
* each test case takes on average 15 minutes to execute and check
* for each 1000 LOC, 5 defects are found
You have used this information to create an estimate for the system testing of a new mobile phone application being developed to submit gas and electricity readings.
The application delivered for system testing has 50.000 lines of code. At the end of system testing, 250 defects are discovered.
Assume that:
* the system test of the new mobile phone application will require the same amount of effort as previous applications
* defect density = number of defects/1000 LOC
* no new tools or processes have been introduced to the test team
Based only on the given information, which one of the following statements is true about this new mobile phone application?
SELECT ONE OPTION
A. 3000 test cases will be executed during system testing and 250 defects will be found.
B. The actual number of defects found is the same as the estimated number of defects.
C. The time taken to run all the estimated tests would be 750 hours.
D. The source code contains a lower defect density than the source code of past applications
正解：B

質問 6：
The Test Manager must assemble team members that have which of the following characteristics?
A. Possess identical skill sets
B. Will spark informal cross training among themselves
C. Thrive in a routine, structured environment
D. Will not change the severity of a defect report
正解：B

A. There is a risk that the system architecture may have to be changed during the development process.
B. A requirements traceability matrix will be created at the start of each iteration.
C. Your developers are using a waterfall methodology.
D. Testing will start when all coding is completed.
