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?

• A. Pressure 950mb, temp. 11°C, fuel 400,000kg, optimal airspeed = 610 knots
• B. Pressure 950mb, temp. 10°C, fuel 360,000kg, optimal airspeed = 620 knots
• C. Pressure 1050mb, temp. 9°C, fuel 350,000kg, optimal airspeed = 590 knots
• D. Pressure 950mb, temp. 9°C, fuel 350,000kg, optimal airspeed = 616 knots

The following use case diagram shows the process of raising a Purchase Request (PR) and getting it authorized. Details are entered in batches; any that fail validation will be rejected and must be re-entered. The details will indicate whether the request is a normal one or an emergency one. Normal requests must be authorized by the department manager, who may refuse to do so. Emergency requests will be automatically authorized and reported to the manager.

The test strategy states that:
* all combinations of extensions and exceptions, as well as the main scenario, shall be tested
* loops shall get simple loop coverage where the maximum number of iterations for validation exceptions is 3 and the typical number is 2.
What is the minimum quantity of test cases that will be needed to obtain this coverage?

• A. 5
• B. 7
• C. 6
• D. 4

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. a) and d)
• B. c) and e)
• C. a) and b)
• D. b) and e)

How is a Test Analyst involved in an Incremental SDLC model?

• A. In each increment, the Test Analyst always performs the same test activities
• B. In all increments, the Test Analyst organises the test activities in the same way
• C. In all increments, the Test Analyst performs the test activities in a dynamic and adaptive way
• D. In each increment, the Test Analyst performs the test activities cyclically
