Software Testing Technology & Digital Applications 4

Question 1

Which approach does Docker primarily support in software testing?

Accepted Answer

Consistent, containerized test environments that eliminate 'works on my machine' issues

Answer

Docker containers package an application with all its dependencies, ensuring tests run identically across developer machines, CI servers, and staging.

Question 2

In testing IoT (Internet of Things) devices, which challenge is MOST distinct from traditional web app testing?

Accepted Answer

Verifying firmware behavior across constrained hardware and unreliable network conditions

Answer

IoT testing must account for low-power hardware, intermittent connectivity, and embedded firmware that cannot easily be updated.

Question 3

What does 'blue-green deployment' allow QA teams to do more safely?

Accepted Answer

Run tests in parallel on two identical environments and switch traffic only after validation

Answer

Blue-green deployment keeps two identical environments; the new release is validated on the inactive environment before traffic is switched, reducing rollout risk.

Question 4

A tester needs to verify that a payment gateway integration handles declined cards gracefully. Which technique is most appropriate?

Accepted Answer

End-to-end integration testing using sandbox credentials provided by the payment provider

Answer

Payment providers offer sandbox environments with test card numbers to simulate various decline scenarios without real transactions.

Question 5

What is 'chaos engineering' and how does it relate to testing digital applications?

Accepted Answer

Deliberately injecting failures into production-like systems to discover weaknesses before they cause outages

Answer

Chaos engineering proactively introduces faults such as network latency or service crashes to reveal resilience gaps before real incidents occur.
