B.S.W.E. Bachelor of Software Engineering Practice 5

Question 1

Which SOLID principle states that software entities should be open for extension but closed for modification?

Accepted Answer

Open/Closed Principle

Answer

The Open/Closed Principle promotes extending behavior through new code (subclasses, plugins) rather than modifying existing stable code.

Question 2

A team uses feature flags to deploy incomplete features to production hidden from users. Which benefit does this provide?

Accepted Answer

Enables continuous deployment while controlling feature rollout

Answer

Feature flags decouple deployment from release, allowing teams to ship code continuously while controlling when and to whom features are exposed.

Question 3

What is the main advantage of writing small, focused unit tests over large integration tests?

Accepted Answer

Unit tests are faster to run and pinpoint failures precisely

Answer

Small unit tests run in milliseconds and fail with a precise indication of which unit broke, making debugging faster compared to slower integration tests.

Question 4

In software estimation, what does 'planning poker' use to reach a team consensus on story point estimates?

Accepted Answer

Individual secret voting with simultaneous reveal to avoid anchoring

Answer

Planning poker uses simultaneous card reveal to surface diverging estimates without anchoring bias, then the team discusses until consensus is reached.

Question 5

Which practice requires every merge to the main branch to trigger an automated build, test, and report cycle?

Accepted Answer

Continuous Integration pipeline

Answer

A Continuous Integration pipeline automatically builds and tests every commit pushed to the main branch, catching integration issues immediately.
