Exam-style question
Try this first
Explain how you would select and present a balanced sample of tests to demonstrate that the requirements of a solution have been achieved.
Model answer
What a good answer should say
- First, identify the requirements that the testing evidence must demonstrate.
- Select tests that collectively provide representative coverage of those requirements, rather than recording every possible test.
- The sample should be balanced so that it does not focus on only one type of behaviour or outcome.
- For each selected test, record the test performed, the test data, the expected outcome and the actual outcome.
Explanation
Why this works
A strong answer connects test selection to the requirements, uses a representative and balanced sample, and explains how the test records and evidence support a conclusion about robustness and achievement of requirements.
