Software Testing Case Studies & Practical Application 5

Question 1

A test team is asked to certify that a medical device software meets FDA 21 CFR Part 11 requirements. This is an example of:

Accepted Answer

Regulatory compliance testing

Answer

Regulatory compliance testing verifies that software meets the specific rules, standards, or regulations mandated by governing bodies such as the FDA.

Question 2

A defect is reproducible on the tester's machine but not on the developer's machine. The most productive next step is:

Accepted Answer

Compare environment configurations between the two machines to identify differences

Answer

Environment differences—such as OS version, configuration, or dependencies—are the most common cause of 'works on my machine' issues, so comparing environments is the logical next step.

Question 3

A QA lead must recommend a test approach for a project where requirements change frequently. Which approach provides the best adaptability?

Accepted Answer

Risk-based testing combined with exploratory testing sessions

Answer

Risk-based and exploratory testing adapt well to changing requirements because they prioritize by risk and rely on tester judgment rather than rigid scripts.

Question 4

A team implements test-driven development (TDD). A developer writes a test for a new function, runs it, and it passes immediately without writing the implementation. What does this indicate?

Accepted Answer

The test is likely not testing the right thing and may be a false positive

Answer

In TDD, a new test should fail first (red phase); if it passes immediately before implementation, the test is probably not actually exercising the intended behavior.

Question 5

A social media platform experiences degraded performance when a viral post drives 10x normal traffic suddenly. Which test type is specifically designed to simulate this scenario?

Accepted Answer

Spike testing

Answer

Spike testing evaluates system behavior under sudden, dramatic increases in load and then monitors recovery once the spike subsides.
