Actual exam question for Databricks's Databricks-Certified-Professional-Data-Engineer exam

Question #: 7
Topic #: 5

[All Databricks-Certified-Professional-Data-Engineer 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 see your point, Arletta. But wouldn't an Integration test make more sense since it's checking the integration of the functions?

Hmm, I'm not so sure. I think it could be a functional test, as it tests the functionality of the mathematical functions.

I agree with Erick, because Integration tests check if different parts of the system work together correctly.

I agree with it sounds more like an integration test to me.

But doesn't the test involve testing the interaction between different functions?

Hold on, 'Manual'? Really? That doesn't seem right at all. This is clearly a question about the type of test, not whether it's manual or automated. Let's not overthink this, people.

You know, I'm just going to go with my gut and say 'Manual'. That seems like the most straightforward answer, and the question doesn't really give any indication that it's an automated test.

Good point. But then again, the question also mentions that the function is 'as described by another function'. That suggests it could be a 'Functional' test, where the focus is on the overall behavior of the system rather than individual components.

I'm not so sure about that. The question specifically says the function is 'one of which calculates the area under a curve', implying that it's just one of several functions being tested. That makes me think it might be a 'Unit' test, as in testing individual components or functions.

I agree with Izetta, it does seem like a Unit test.

Hmm, I'm leaning towards option A, 'Integration'. The question mentions testing a function that calculates the area under a curve, which sounds like it could be related to integration, a fundamental concept in calculus.

This seems like a tricky one. The question is asking about the type of test being performed, and I'm not entirely sure which option best fits the description.
