How to collect the code coverage of your tests in .NET

[@yumyumrocks1]

Fine Code Coverage is a great extension for visual studio for showing the coverlet in the actual ide.

[@andersborum9267]

Agree; have been using it for a long time and it's a great addition to VS.

[@barmetler]

That's so cool, this way you can just host the coverage online somewhere and let your CI update it, and the entire testing team can easily see what tests need to be implemented.

[@felgedits]

Thanks! This really helped with integrating a nice code coverage report to my build.

[@antonkomyshan1727]

one of the most important theme in real work IMHO. Thx)

[@GioacchinoPiazzolla]

Hi Nick. Are you going to do a video on Microsoft's native Code Coverage in the near future?

[@th3oth3rjak3]

This is a great way to visualize the coverage. I am trying to find a way to have it autogenerate some of this for me so I don't have to manually type the commands each time. It looks like a .runsettings configuration could be the way, but I haven't figured out how to do it. Could we do this automatically with a configuration setup?

[@byrondelgado8165]

is this useful to get the code coverage after Run Automated Tests? if isn't, do you know any other tool to do so.?

[@AntonioMSpb]

Thank you, it was useful 👍

[@itania2266]

Excelent video, thank you! But could you please prompt how can I collect the code coverage of all my tests at the same time if I have more than one In my project?

[@ghostslinger3148]

Hi Nick, thanks for the great tutorial! if we want to exclude multiple files on the collecting XPlat code coverage so that it does not show in the report generator, how do we do this?

[@diale13]

Loved the video!

[@rahulchaurasia5560]

Hey nick, I have a question here, I can't see anywhere the Unit tests count, I need to show this in Sonar Dashboards, but whatever the report is being generated, I can't see the unit tests count

[@sri3884]

Hi , thanks a lot , it really helpful.

[@sagarfulari2765]

Instead of line coverage and branch coverage... Can I generate block coverage report.. Please reply

[@bvsjagan]

How is the Total % is different from Average % when coverage is generated via command line?

[@tejaspatel1679]

If you have multiple dlls, that would generate multiple reports - how would you merge them all?

[@Yoko-0x0]

Thanks for the video, it helped me a lot. question out of context. what webcam do you use?

[@nickchapsas]

I use a Sony ZV-1 with a Camlink 4k

[@Yoko-0x0]

@@nickchapsas thanks

[@ronaldoperes1202]

That is very good, Can you tell me how can I collect the code coverage of a project with Specflow that do the BDD to do the integration tests?

[@thespicycoder5583]

If you are using webapplicationfactory in your integration test project, same approach Nick shown should work. Irrespective of you use specflow or not, it should still work.

[@ilkerayti]

Where did you choose for your vacation? It's obvious that you're sunbathing on your face :) Nice video. Keep coding.

[@nickchapsas]

Hahaha, is it that obvious?? I was back home in Greece for a couple of weeks :D

[@ilkerayti]

@@nickchapsas Ahaha I am from Turkey and live in Izmir that is very close to Greece. Since I am also very white, it is immediately evident on my face at the slightest holiday :))

[@philc8544]

Does this work for .net framework Nick?

[@mridulpaul1378]

Data collection : Could not find data collector 'XPlat Code Coverage' - getting error

[@matrixlukan]

Can you please make a video on ABP framework?

[@ИванИванов-я5э9к]

What if I have several projects with tests?

[@kayasso]

anyone know how to exclude the views folder?

[@vaddiparthivenkatamuralikr8334]

excellent

[@subhrajitmazumder7122]

Thanks for helping us through this great tutorial. Could you make a video on how to import a coverage.xml file in SonarQube ? Please pick my question

[@andrenunes4032]

nice!

[@matteobarbieri2989]

Why don't you make some video on Unit Testing. There's a lot of people that simply ignore them

[@nickchapsas]

I already have one on TDD

[@arthursoares610]

Hi Nick. I would like to use your video about MediatR and CQRS as part of software engineering onboarding at my company. But we are allocated in Brazil and not every engineer speak English very well. Could you please enable subtitles editing on your videos? I'll add the translations by my self. Thanks a lot!!!

[@victorgarcia3526]

So this all was just to flex on us about his ridr license

I think Visual Studio is better than Rider at this point. Visual studio allows us to navigate the code, see which statements (not lines) are covered. It's build-in and we don't have to install any library or tool. However, it's available only on the Enterprise version.

[@Zikakoo]

VS Enterprise is $250 a month and commercial license for Rider is $349 a YEAR. So not really comparable.

@@Zikakoo I didn't say everyone should use Visual Studio instead of Rider because of this idea or do an advertisement for Visual Studio. This is just a comparison for a single feature and everyone should agree that Visual Studio is better than Rider in some points and Rider is better in some other points. I'm using and happy with both.

@@Zikakoo One other thing is when you pay 349 per year, what you have it the license for Rider. That's all. When you pay 250$ per month for VS Enterprise, you have a service and you have benefited from Windows (xp, vista, 7, 10) licenses, Office (plus version, not 365) license, 150$ Azure monthly credits, Pluralsight and a lot more benifit. I can't list them all in a short comment. So, comparing 250$ per month and 349 per year as you did is NOT fair. Anyway, I didn't intend to recommend anyone to use Visual Studio instead of Rider.

Hopefully JetBrains folks going to implement something similar soon.

@ They should start by attempting to speed up ReSharper first, or at least have it not hang up VS completely while it's initializing. Even in VS 2022 (which is already faster on itself, compared to VS 2019) ReSharper slows down starting up VS and loading solutions tremendously. Luckily for them having it available is still preferred by us over the speed gained in VS by removing it.
