The path is empty. (Parameter 'path') #775

Adam-RapidRTC · 2020-03-23T18:15:31Z

Having an issue generating the report. The project is SDK format but references older projects. When I run'

(actual paths omitted)
dotnet test "....csproj" --configuration Release --filter Category!=IntegrationTest --logger:trx --results-directory "...\TestResults" --settings "....runsettings" /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput="....Tests.cobertura.xml"

I get the following error

Calculating coverage result...
Generating report '....Tests.cobertura.xml'

This works for several other projects in the solution that don't have a reference to older projects.

I also noticed I get these warnings when building:

Hi Adam,

thank's for reporting this, can you try to generate a small repro?

@daveMueller seem an issue here https://github.com/tonerdo/coverlet/blob/master/src/coverlet.core/Reporters/CoberturaReporter.cs#L166 do you have any idea?

I also noticed I get these warnings when building:

Warnings are ok...we cannot instrument dll without local source so they're expected.

MarcoRossignoli · 2020-03-28T08:54:50Z

@Adam-RapidRTC despite bug, can you try with collectors you already use runsettings, vstest integration is the better way to consume coverlet at the moment https://github.com/tonerdo/coverlet/blob/master/Documentation/VSTestIntegration.md

Never mind...you're on .NET Framework not .NET Core one.

MarcoRossignoli · 2020-03-29T16:06:30Z

@Adam-RapidRTC can you try to run in debug mode and tell me if the issue is still present?
I found the place of the issue, btw I'd like to understand how it's possible, seem that pdb for some project reports empty path file.
We can fix this particular issue inside report generation, but I'd like to understand why that empty path exists.

Are you able to create a small repro?

Adam-RapidRTC · 2020-03-30T14:32:11Z

@MarcoRossignoli I will see if I can carve out some time today and create a sample repo that recreates the problem.

MarcoRossignoli · 2020-03-30T19:44:03Z

Thanks a lot!

daveMueller · 2020-04-01T14:53:44Z

@daveMueller seem an issue here https://github.com/tonerdo/coverlet/blob/master/src/coverlet.core/Reporters/CoberturaReporter.cs#L166 do you have any idea?

Yes seems the CoverageResult has a Document with a empty path. I could add a check for this but I'm not sure if the CoberturaReporter is the right place for this.
I guess the other reporters could also have a problem with such a CoverageResult.
So @Adam-RapidRTC a repro would help a lot to tackle this issue.

Adam-RapidRTC · 2020-04-02T15:27:29Z

@daveMueller @MarcoRossignoli - Sorry for the delay but I'll work on getting that demo repo up for you today.

MarcoRossignoli · 2020-04-02T15:38:05Z

No prob no rush at your pace, thanks.

MarcoRossignoli · 2020-06-13T19:23:21Z

@Adam-RapidRTC any news?

NerdBrez · 2020-12-18T23:44:00Z

Any update about this issue?

daveMueller · 2020-12-18T23:56:28Z

@NerdBrez Are you facing the same issue with cobertura report? Could you create a small repro?

NerdBrez · 2020-12-19T00:18:36Z

Yes, I'm trying to generate a report on my xUnit test. The test project references an .Net framework 4.7.2 web application and performs 8 tests on some MVC controllers.
The tests pass but then coverlet raises the errors when generating the reports:

dotnet test lqe.web.test --framework net472 --no-build /p:CollectCoverage=true /p:CoverletOutput=../TestResults/Coverage/ /p:MergeWith="../TestResults/Coverage/coverage.json" /p:CoverletOutputFormat="cobertura,json" -m:1

Ok thanks. @NerdBrez can you share/attach your project to this issue? Or at least the parts that lead to this issue (maybe the controllers and the tests or so). Otherwise I will try to set up a sample to reproduce this.

daveMueller · 2020-12-22T23:36:36Z

Today I set up an MVC project with 4.7.2 framework and XUnit 2.4.1 unit tests. Unfortunately everything worked without a problem and I couldn't reproduce the issue described above. A small sample project that has the same error would help a lot.

NerdBrez · 2021-01-06T21:10:44Z

Hello,
My MVC application (C#) have a project reference to a library coded in VB in the same solution.
When I remove it from te coverage with the Exclude parameter, it works fine. No idea why...

daveMueller · 2021-01-07T01:27:31Z

Cool thanks for the info. I will give it a try with a additional VB class library in the solution. I'm currently really busy so it could take a couple of days to test this 🙏.

daveMueller · 2021-01-21T06:19:01Z

The hint with the VB project that @NerdBrez provided was worth its weight. I set up a solution with an MVC project with XUnit and a VB class library project that let me reproduce this error. Here is the repo => https://github.com/daveMueller/coverlet775

Up to now I didn't find the time to debug into this but I will in the next days. Just to let you know that we are still on this. And at least we have a repro now 😉.

daveMueller · 2021-01-28T01:30:54Z

The issue is the My namespace in Visual Basic (My). Usually a sequence point has a reference to a source file like this.

In Visual Basic the compiler injects the My classes into the assembly without a reference to a source file.

Maybe there are also other scenarios where a sequence point doesn't have a reference to a source file that we haven't encountered yet. So I created a PR that excludes code like this within an assembly.

daveMueller · 2021-01-28T01:36:01Z

By the way I updated the repro to be a lot smaller than the first implementation (https://github.com/daveMueller/coverlet775).

sebastianslutzky · 2023-01-17T14:32:36Z

hi. this issue is still open, but is there a workaround? I am hitting the same problem with an old vb project I converted to sdk style

daveMueller · 2023-01-24T00:00:48Z

Hi @sebastianslutzky, I worked on the PR again and think it fixes the issue. I compiled the source locally and I would be happy if someone could give it try with the packages attached here.

Hi @daveMueller, I got the "The path is empty. (Parameter 'path')" when I use coverlet.console 3.2.0 in my test projects. I tried replace the files using your package and the error is gone!. When this fix will be officially released?

The parameter InstrumentModulesWithoutLocalSources has been removed. since it can be handled by setting ExcludeAssembliesWithoutSources to None. The default heuristics for determining whether to instrument an assembly has been changed. In previous versions any missing source file was taken as a signal that it was a third-party project that shouldn't be instrumented, with exceptions for some common file name patterns for source generators. Now only assemblies where no source files at all can be found are excluded from instrumentation, and the code for detecting source generator files have been removed. To get back to the behaviour that at least one missing file is sufficient to exclude an assembly, set ExcludeAssembliesWithoutSources to MissingAny, or use assembly exclusion filters for more fine-grained control.
