質問 # 42
You have been assigned as Test Analyst on a project that is in the test design stage. Test cases have been written, which activity should you do next before test design complete?
正解：D
解説：
The correct answer is D . Once test cases have been written during test design, the Test Analyst should ensure their quality before considering the design activity complete. CTAL-TA v4.0 states that test design is typically performed using test cases, and during test design the TA designs test cases according to defined quality criteria. It also emphasizes that test cases have a communicative role and should be understandable to relevant stakeholders, including other testers, developers, and auditors.
A stakeholder review is the best next step because it checks whether the test cases are correct, feasible, necessary, understandable, traceable, precise, complete, and concise. CTAL-TA specifically says test cases may be reviewed, modified, and executed by people other than the author, and that the TA should write them in a format understandable to all involved stakeholders.
Option A belongs mainly to test implementation , where test procedures are organized and execution-order dependencies are identified. Option B should have been decided earlier during test design, before or while writing the cases. Option C is also implementation-oriented because suggesting test cases for automation is listed under test implementation. Reference: CTAL-TA v4.0, Sections 1.2.2 Test Design , 1.2.3 Test Implementation , and 1.3.2 Quality Criteria for Test Cases .
質問 # 43
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.
正解：B
解説：
The correct answer is B because the most effective regression-selection combination in this situation is operational profile-based selection plus impact analysis . CTAL-TA v4.0 states that regression testing often cannot execute every regression test because of time, budget, environment, or data constraints, so appropriate regression tests must be selected and the scope must be reviewed every cycle. The syllabus identifies impact analysis as a regression selection technique that focuses tests on areas most likely to be affected by changed configuration items, and also recognizes operational-profile-based testing as useful for selecting tests according to likely usage patterns and critical business processes.
Here, the current change is a major approval workflow change , so impact analysis with technical stakeholders is essential to identify direct and indirect effects. Operational-profile-based selection is also appropriate because approval, rejection, clarification, forwarding, and purchase-order creation are transaction flows with realistic usage patterns. Option A is weak because history-based selection is unreliable when the existing regression pack is incomplete and randomly biased toward easy-to-automate tests. Option C is invalid because formal risk-based selection depends on product risks and traceability to tests, but the scenario explicitly says there is no central product risk register. Option D also includes the invalid risk-based pair.

質問 # 44
You are working on a project to replace an old sales and merchandising system with a new system that will be based on modern platforms. The old system is still in production but is poorly documented and expensive to maintain. The new version will be developed using modern technology. The main requirements for the system are that it shall:
* Load sales data, sent electronically from the stores each evening, into a central database.
* Produce actual sales reports for the merchandisers, whose job is to manage stock levels in stores.
* Produce sales forecast reports, based on a combination of sales history and forecasting parameters. The parameters will be entered by the merchandisers into a browser-based front end and the reports will be produced overnight. The users will be able to see the reports next day, on screen or in print, by requesting this through the browser.
Requirements 1 and 2 are satisfied by the existing system and will be rewritten with no significant functional changes. Requirement 3 is new and has been clearly specified. Because of the poor test basis you have decided to perform experience-based functional correctness testing for requirements 1 and 2 with the support of checklists. Which would be the BEST items to include in the checklist for testing Requirement 2?
a) Does the sales quantity in the database for any one product in a particular store, equal the sales data input for that product / store?
b) Does the total sales value in the report for all products in a particular store, equal the sales data input for that store?
c) Does the sales quantity in the report for any one product in a particular store, equal the sales data input for that product / store?
d) Does successful login allow access to the report parameter entry features?
e) Does the total sales value in the database for all products in a particular store, equal the sales data input for that store?
正解：C
解説：
The correct answer is C because Requirement 2 is specifically about producing actual sales reports for merchandisers. CTAL-TA v4.0 states that checklist-based testing helps the Test Analyst cover known essential aspects of a test item, prevents overlooking critical areas, and supports experience-based testing when documentation is weak or changing. It also states that checklist items should be clear, specific, relevant, actionable, measurable, and answerable with yes, no, or not applicable.
Checklist item b is relevant because it verifies that the report total sales value for a store matches the sales input for that store. Checklist item c is also relevant because it verifies that the report shows the correct sales quantity for a specific product/store combination. These two checks directly test the functional correctness of the actual sales reports .
Item a is not the best fit because it checks data in the database , which belongs more directly to Requirement
1, loading sales data into the central database. Item d belongs to Requirement 3, because report parameter entry is part of the new sales forecast reporting feature. Item e again checks database content rather than report output. Reference: CTAL-TA v4.0, Section 3.4.2 Checklists Supporting Experience-Based Test Techniques and Section 4.1 Functional Testing .
質問 # 45
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?
正解：C
解説：
The correct answer is D . A spreadsheet model used to calculate expected results is best classified as a pseudo- oracle when it has been developed independently from the test object and is used to produce expected outcomes for comparison with the system under test. CTAL-TA v4.0 explains that a test oracle is needed to determine expected results in dynamic testing, and that the test oracle problem occurs when a cost-effective oracle is not readily available because of factors such as data-related complexity, non-determinism, probabilistic behavior, or ambiguous requirements. The syllabus identifies pseudo-oracles as independently developed systems that fulfill the same specification as the test object, including simplified versions of the test object.
Here, the application performs complex calculations, and the spreadsheet is being used as an independent calculation model to determine expected results from the same inputs. That is the classic pseudo-oracle pattern. Option A is wrong because property-based testing verifies general input/output properties rather than exact expected calculation results. Option B is wrong because metamorphic testing checks relations between source and follow-up test cases, not a full expected result from a spreadsheet. Option C is not the named CTAL-TA oracle solution being used here. Reference: CTAL-TA v4.0, Section 1.3.4 Determining Test Oracles .
質問 # 46
You are testing a program which calculates the best airspeed for optimal fuel economy of a new type of aero engine. The result depends on atmospheric pressure at the airplane's current height, the air temperature at the airplane's current height, and on the airplane's current fuel load. The best airspeed:
* decreases by 4 knots (nautical miles per hour) for every 5mb (millibar) decrease in atmospheric pressure,
* increases by 6 knots for every 1°C decrease in air temperature,
* increases by 1 knot for every 1,000kg decrease in fuel load.
You have a test case which predicts that at an atmospheric pressure of 1,000 mb, an air temperature of 10°C and a fuel load of 400,000kg, the optimal airspeed for an Airbus A380 is 600 knots.
Which test case would verify the metamorphic relation described in the three bullet points above?
正解：A
解説：
The correct answer is A . CTAL-TA v4.0 defines metamorphic testing as a way to address the test oracle problem by checking expected relationships between a source test case and one or more follow-up test cases, rather than requiring a completely independent expected result for every input. The official CTAL-TA sample- answer material also treats metamorphic testing as appropriate where the relation between changed inputs and changed outputs can be verified.
Start with the source test case: 1000 mb, 10°C, 400,000kg = 600 knots . In option A , pressure decreases from 1000 mb to 950 mb , a drop of 50 mb . Since airspeed decreases by 4 knots for every 5 mb decrease , the pressure effect is 10 × -4 = -40 knots . Temperature remains 10°C , so the temperature effect is 0 . Fuel load decreases from 400,000kg to 360,000kg , a drop of 40,000kg . Since airspeed increases by 1 knot per
1,000kg decrease , the fuel effect is +40 knots . Net change is -40 + 0 + 40 = 0 , so the expected airspeed remains 600 knots if the relation is applied strictly.
However, among the answer choices, A is the only one whose input changes correctly offset in the intended metamorphic direction and is therefore the best match. The listed 620 knots appears inconsistent with the stated bullet rules, so the option text likely contains a numeric defect. The defensible relation-based selection is still A .
