Question #: 19
Topic #: 1

[All Databricks Certified Data Engineer Professional Questions]

A data engineer is testing a collection of mathematical functions, one of which calculates the area under a curve as described by another function.

Which kind of the test does the above line exemplify?

AIntegration

BUnit

CManual

Dfunctional

Show Suggested Answer

Suggested Answer: B

A unit test is designed to verify the correctness of a small, isolated piece of code, typically a single function. Testing a mathematical function that calculates the area under a curve is an example of a unit test because it is testing a specific, individual function to ensure it operates as expected.

I'll have to go with C. Manual testing. After all, who needs automation when you've got a trusty calculator and a lot of patience?

Haha, this is a real head-scratcher. Maybe we should just ask the data engineer to bring a slide rule to the exam.

I'm going with B. Unit testing. The question mentions testing a 'collection of mathematical functions', so it's probably evaluating individual units.

Yes, I think so too. Integration tests check if different parts of the system work together correctly.
