Databricks Certified Data Engineer Professional Exam - Topic 5 Question 7 Discussion

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

Question #: 7
Topic #: 5

[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.

Really? I thought unit tests were for smaller functions only.

I feel like this question is similar to one we did in class about testing mathematical functions, and I think it was a unit test then.

Functional testing sounds familiar, but I can't recall if it applies here. I need to think about the context more.

I think this might be a unit test since it focuses on a specific function, but I'm not entirely sure.

Okay, I've got it. Since we're testing a function that calculates the area under a curve, that's a specific type of integration test, where we're verifying the interaction between different components. I'm confident that the answer is A, Integration.

I'm a bit unsure on this one. The question mentions "mathematical functions", so it could be a unit test as well, testing each function individually. I'll have to think this through carefully.

Integration test, for sure. We're testing how the different functions work together, not just individual units. Gotta make sure the whole system is functioning properly.

Hmm, this seems to be testing our knowledge of different types of software testing. I think the key here is that the question mentions testing a "collection of mathematical functions", one of which calculates the area under a curve. That sounds like it could be an integration test.

This seems like a straightforward question about SOAP web services. I'll need to think carefully about the different service types and which one is used for obtaining access tokens.

I'm feeling pretty confident about this one. The question is asking how to facilitate the welcome journey, so Option D which links the data extensions in the right way is the correct answer.

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.

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.

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.
