Question

The quality assurance (QA) team is testing a new e-ticketing application prior to go live to ensure that sales tax is calculated and applied correctly. Which of the following should be of GREATEST concern?

Options

  • AUser procedures to manage the e-ticketing application are still being drafted
  • BThe tax schedules are not uploaded into the production database
  • CThe project manager wants to delay implementation by a few days
  • DUser acceptance criteria for the test performed are not clearly defined

  • B
    73% (29)
  • C
    3% (1)
  • D
    8% (3)

Explanation

Option B is the greatest concern because without tax schedules loaded into the production database, the QA team literally cannot test what they set out to test - any results on sales tax calculation would be meaningless or based on missing/incorrect data, making the entire testing effort invalid before it begins.

  • A is wrong because user procedure documentation being incomplete is a training/operational concern that does not block or invalidate the accuracy of the tax calculation test itself.
  • C is wrong because a short implementation delay is a schedule concern, not a data integrity or test validity issue - the system can still be tested correctly once deployed.
  • D is wrong because while unclear acceptance criteria is a legitimate QA concern, it affects how results are evaluated, not whether the underlying data needed for the test even exists.

Memory tip: When a question asks about testing data-driven functionality (tax, pricing, rates), always ask "Is the data there to test against?" - missing reference data is a showstopper that makes all other concerns secondary.
