Topic #: 1

[All PSD Questions]

You are asked to refactor part of the codebase for an application. When you are done, all unit tests pass with 50% code coverage. What can you infer from this?

ALess than 50% of the application is working correctly

BThere are no bugs in the application

CAt least 50% of the application is working correctly

DYou did not break any of the unit tests that already existed

Show Suggested Answer

Suggested Answer: D

You can't really say anything because you don't know what the unit tests are testing and whether they are correctly representing whether the application is working correctly. However, if all the tests passes you didn't break any already existing tests. Also, if none tests existed yet, you did not break them.

Totally agree with C, at least half is working!

A is misleading; coverage doesn't equal correctness.

Surprised that 50% coverage means anything at all!

I think D makes more sense, though.

I guess option D could be true since all existing tests passed, but I'm not completely confident about the implications of 50% coverage.

I feel like just passing tests doesn't guarantee there are no bugs, so option B seems off to me.

I think I saw a similar question in practice exams, and it seems like option C makes the most sense.

I remember discussing code coverage in class, but I'm not sure if 50% means half the app is working correctly.

I'm a bit unsure how to approach this - should I use a specific example or just talk about the general effects of organizational behavior?

This is a great question to test our understanding of Meraki API usage. I'm confident I can identify the correct line of code to complete the request.

This seems like a straightforward question about capacity planning. I'll think through the options carefully and choose the one that best fits the description.

Alright, let me walk through this step-by-step. We have an existing alpine image, and we need to create a new container from it. The key is the "-p" option, which maps the container's port 8080 to the host's port 80. I think the answer is "docker run -p 8080:80 alpine:latest".
