Hello, I’m using SonarCloud and I have c# source code using Task and async methods. There is 2 ways I can write the code e.g.: // version without async Task DoSomething() { return Task.Delay(1000); } // version with async async Task DoSomething(){ await Task.Delay(1000); } When using the…

Hi @Laurent The fix has been deployed today, could you confirm that it indeed solved the issue on your side? Anita

[image] Marc-Andre: he coverage reports generated are a bit different but both contains all the information. Do both coverage reports show that these lines can be covered by code? SonarQube isn’t involved in producing the coverage reports – only reading them.

[image] Colin: Do both coverage reports show that these lines can be covered by code? I don’t know exactly how to know that but I think yes. I can say that in the report not using async, the information on coverage is part of an element referencing the class in which the method is defined. E…

This might also be relevant. [image] Lines to Cover Does not Include Async Methods? SonarQube Got it based on your feedback. I hadn’t looked to see if it could be a Visual Studio problem which is apparently is. Thank you! For anyone else looking: Visual Studio Feedback …

Thanks for your reply I saw that blog post you mentioned but I’m not sure it’s the same case. Now I don’t really know if it’s a problem in the way Visual Studio generates the report or not (because I don’t know what it is supposed to look like). One thing I know is that the information is in the …

A reproducer is always helpful. :slight_smile: [image] Marc-Andre: E.G. the number of Uncovered lines is right in both case. I would expect this. If the lines are found as executable (able to covered by tests) and covered… you end up with the same number of uncovered lines as if they aren’t …

Well, in my async method, some lines are covered and some other lines are not covered. Yet, all the metadata (lines to cover, uncovered lines, …) is the same between the 2 coverage reports. I did a small demo project and generated the coverage report. There are 2 methods in the class under test: p…

Thanks for the details. I’ve flagged this for some expert attention.

Hi lepagema can you please show the command and the version of the tool that generated the coverage report? To me, it looks like a limitation of the tool as it doesn’t properly handle the async state machine transposition of the compiler. Best Martin

Hi @Martin_Strecker We send a Generic test data (sonarqube.org) xml files, so clearly not an issue on the tool… And we got the problem, for instance the file contains: <file path="MvtMain\Services\Components\Loader\ComponentLoader.cs"> <lineToCover lineNumber="309" covered="true"/> <lin…

Hello @Laurent Could you please create a minimal reproducer project and share it with us (e.g. github repo)? Please mention in the README the commands that you are using. This will help us jump on the topic quicker and kickstart the investigation.
