質問 1：
Your project is developing an application to generate quotes for motor insurance. The calculation requires a wide range of input data and a reliable model of it has been built in a spreadsheet. There will not be enough time to get adequate functional correctness coverage from the base choice or pairwise techniques, so you have decided to do some random testing based on a probability distribution of variable values that is weighted towards their business criticality.
Which limitation of random testing should you be MOST concerned about?
A. Dependency on an automated test oracle to establish test results
B. Generating tests that will exercise the same conditions repeatedly
C. The tests will focus on validation rather than verification
D. Missing defects that are rooted in the meaning of data semantics
正解：D

質問 2：
You are working on a project to build a purchasing system. The main requirements for the system are that it shall:
* Allow users to enter details of items that they would like to purchase and, from these details, create a purchase request.
* Take each purchase request through a workflow that will allow the requestor's line manager to approve the request, reject it, or return it for clarification / modification.
* Forward approved requests to the Purchasing Department.
* Allow purchasers to find the best available supplier for each approved request and place the request on that supplier as a purchase order.
The system is being developed following an Agile SDLC. Risk-based testing is practiced informally, discussion about what testing each user story will need being done in a risk-driven way during story refinement, but there is no central product risk register. Testing is exploratory, except for the acceptance tests for each story's acceptance tests. Operational profiles have been created to guide performance testing.
Regression test automation started late. The team want to automate all acceptance tests for every user story, but the test automation engineers are still playing catch up. They started with the tests that were easiest to automate, so the functional and non-functional coverage of the regression test pack is incomplete and random.
The current iteration is delivering a major change to the approval workflow and you, as a Test Analyst, have been tasked with defining the regression testing.
Which techniques would be MOST effective for selecting regression tests?
a) History-based, driven by the results of the regression tests run so far b) Risk-based, driven by the product risks and their traceability to the tests c) Operational profile-based, driven by the likely patterns of use of the relevant transactions d) Coverage-based, driven by the coverage obtained from use of relevant test techniques e) Impact analysis, driven by consultation with technical stakeholders to identify what might be affected.
A. c) and e)

質問 4：
You are a TA in the development of a road traffic control application, which will be installed at busy road junctions, to control the operation of traffic signal lights according to sensors that detect traffic volume. This safety-critical project is still in the early stages of test planning and the project schedule is tight.
The Test Manager has asked you if crowd testing should be included in the project's test strategy. You do NOT think it should. Which limitation of crowd testing MOST influences your view?
A. Ensuring comprehensive test documentation and managing a large number of findings can be challenging
B. Sharing software with external testers poses data security and confidentiality risks
C. Testing quality can vary significantly depending on the skills of individual testers
D. Coordinating with testers in various locations and time zones, with cultural differences and language barriers, can be challenging
正解：C

質問 5：
How is a Test Analyst involved in an Incremental SDLC model?
A. In each increment, the Test Analyst performs the test activities cyclically
B. In all increments, the Test Analyst performs the test activities in a dynamic and adaptive way
C. In all increments, the Test Analyst organises the test activities in the same way
D. In each increment, the Test Analyst always performs the same test activities
正解：D
