問題 #1
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 wish to have purchased 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 solution is being developed according to the company's traditional V-model methodology. The requirements are clearly documented and include a business process model.
The main release has now been live for three months and you are working on the first maintenance release.
The test manager has asked you, the senior TA, to identify those parts of the test process which were most and least effective at finding defects in the main release.
You have collected statistics for the independent test activities, i.e. excluding developers' testing, including only the 178 defects in the three highest of your five defect severity levels. The results are presented in the table below:

Assume that all defects not found at the first opportunity could have been, e.g. that all defects that escaped into acceptance testing were within the scope and objectives of system testing. By applying Defect detection percentage (DDP) analysis, which test activity was LEAST effective?

A. Acceptance testing
B. Test design, including solution design review
C. Test analysis, including requirements review
D. System testing

問題 #2
You are developing test cases for an application which performs complex calculations and have decided to model these calculations on a spreadsheet, to determine expected results from inputs.
Which solution to the test oracle problem BEST describes the approach you are using?

A. Metamorphic testing
B. Deterministic testing
C. A pseudo-oracle
D. Property-based testing

問題 #3
In which of the following circumstances is the transition from a high-level test case to a low-level test case MOST LIKELY to be deferred from test design to test implementation?

A. When product risk analysis has not been completed
B. When specific test data are needed for the test case
C. When the details required depend on the test execution schedule
D. When the person who runs the test will not be its author

問題 #4

* Allow users to enter details of items that they wish to have purchased 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.

* Allow purchasers to find the best available supplier for each approved request and place the request on that supplier as a purchase order.

System testing has finished and the test manager has asked you, the senior TA, to identify any parts of the product that should be focused on during acceptance testing. The results of this may be used to adjust the acceptance test plan.
You are using defect cluster analysis, only counting defects with severity levels 1 to 3, ignoring low severity levels 4 and 5. Function point analysis was used for estimating, so you have used function points as the unit of size for the various functional areas of the product. No numeric estimates of expected defect quantities were made for them individually but, as a result of product risk analysis, these functional areas have been ranked according to the amount of product risk that was predicted in them, with risk ranking 1 being the highest and
5 the lowest; the thoroughness of the testing performed so far has been proportional to that. The results are presented in the table below.

Which functional areas would you recommend for more test focus in acceptance testing?
a) Purchase Request entry
b) Purchase Request workflow
c) Purchase Request authorization
d) Supplier Identification
e) Purchase Order creation

A. a) and b)
B. c) and e)
C. a) and d)

問題 #5
The following minimized decision table shows the rules for rewarding members of a hotel's loyalty scheme who have booked a room, according to the type of room (luxury or not) and/or whether they have prepaid for breakfast (yes or no). The loyalty scheme has tiers Bronze, Silver and Gold. All combinations are feasible.

Using the checksum procedure, what do you notice about the structure of the minimized table?

A. The table may have been minimized correctly
B. The decision table is incomplete, in the sense that at least one condition value is not represented in any of the rules
C. There are additional rules that are not shown
D. There is rule overlap, in the sense that one combination is covered by > 1 rule, or additional rules are not shown
