During a sprint retrospective it was noted that some test cases were interpreted differently between the Product Owner and the Test Analysts. Which test case quality criteria may need some attention?

• A.Precision
• B.Completeness
• C.Consistency
• D.Understandability

The test basis for your latest project contains the activity diagram that is shown below. The business architect has confirmed that this model has been reviewed and approved by the stakeholders.

Which of the following conclusions is correct?

• A.The diagram contains at least one defect because it contains an internal inconsistency
• B.The diagram may contain a defect but this cannot be confirmed until the results of the tests created from it are known
• C.The diagram is correct because it has been reviewed and approved by the stakeholders
• D.The diagram may contain a defect but this cannot be confirmed until test cases have been designed from it

You are testing a program which should calculate the area of a trapezium and have decided to use metamorphic testing. The formula Area = (((a + b) / 2) * h) where a and b are the lengths of the two parallel sides, and h is the height when the parallel sides are horizontal.
Which ONE of the following would be an appropriate metamorphic relation?

• A.If b increases by x% then area increases by ((x * 2) / 3)%
• B.If b increases by x then h increases by ((x * 2) / 3)%
• C.If b increases by x% then h increases by ((x * 2) / 3)%
• D.If b increases by x then area increases by ((x * 2) / 3)%

You are your employer's most experienced TA. The organisation performs root cause analysis (RCA) thoroughly, but infrequently and only on individual defects that went live at the highest of the five Severity levels.
After six months of live operation for one system, particular concern has been expressed about the volume of usability and security defects and there is a strong desire to reduce their quantities. You have recommended adding product quality characteristics, per ISO 25010, to the defect report template.
How might this recommendation support RCA?

• A.In combination with knowledge about how the defect was fixed, it will speed up RCA
• B.Classification by Quality Characteristic will enable more detailed analysis of the defect detection percentage (DDP)
• C.In combination with Severity, Quality Characteristic will isolate groups of defects that are causing most concern, so that RCA can be performed at group level
• D.It will enable Pareto analysis to be performed across the quality characteristics, in order to focus on those which have most defects

You have been appointed to be 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 on the various approaches to the junction. The project is still in the early stages of test planning, but it is already clear that despite a tight schedule its safety-critical nature demands careful and thorough testing.
You have been asked to decide whether automated test design would deliver benefits. Which characteristic of automated test design is MOST important for the development of this system?

• A.Creating the model will expose defects in the test basis early in the project
• B.Testware generated by tools usually contains fewer mistakes than testware created manually
• C.Less maintenance effort for the testware after the system has gone live
• D.Testware can be generated in various output formats, e.g. for use by different tools
