Unable to see code coverage in Integration Test API Endpoint using TestHost and related type

[Ankit_Sangani]

Hello All,

Please Help I m stuck here.

I can not able to generate code coverage of my API endpoint test cases.

I tried with following commands. but code coverage showing 0.

restore
dotnet restore “”

begin
dotnet sonarscanner begin /k:"" /d:sonar.host.url="" /d:sonar.login=""

build
dotnet build “” -c Release -o /app/build

coverage
dotnet test “” /p:CollectCoverage=true /p:CoverletOutputFormat=opencover

End
dotnet sonarscanner end /d:sonar.login=

Hi Ankit,
Welcome to the community
SonarCloud does not automatically calculate test coverage. You need to use an external tool, like Jacoco to produce a coverage report, which SC then imports. For some help, have a look here:

JaCoCo import troubleshooting

This guide will help you diagnose and resolve issues related to JaCoCo coverage import on SonarQube/SonarCloud. Principles apply to all sorts of coverage reports, though there are few caveats specific to JaCoCo. Problems you have Your coverage displays 0%? It dropped after a SonarQube upgrade? You had a coverage value on the project Dashboard and suddenly nothing? Your coverage is really low compared to what is expected? Figures don’t match between JaCoCo and what’s reported by SonarQube? ​…

Hi Peeter,
Thanks for reply
As I have written test case like directly call API endpoint(s). So its not cover whole line of my code.
Written Test case like this.

And Code-coverage output is

So Please help on this.

Hello @Peeter_Piegaze ,

Please help on this.

I have found one link on R & D. visual studio 2013 - Sonarqube C# unable to display Integration test/coverage results - Stack Overflow says that Integration test not supported in sonar.

Is Integration test support on sonar to generate code coverage ?

If Yes then How… I was stuck on last one week @All Please Help.

Hi Ankit,

As I mentioned, you need to set up the tool to produce code coverage yourself, then configure SonarCloud to read the report. Since it looks like you are using C# you might want to have a look at this post:

[Coverage & Test Data] Generate Reports for C#, VB.net

To include test coverage in your analysis, you’ll need to: provide the relevant analysis parameter to the SonarScanner for MSBuild begin step execute your unit tests just after build and before the SonarScanner for MSBuild’s end step. We support: Import of coverage reports from VSTest, dotCover, OpenCover, Coverlet, Altcover and NCover 3. Import of unit test results from VSTest, NUnit and xUnit. We’ve documented here for each engine: what is the relevant analysis parameter to pass during…

HI @Peeter_Piegaze,

Yes, I follow that and generate code coverage of Unit Test in C#. But cant generate for Integration Test report. In my solution we wrote integration test cases for WEB Apis. So I need to generate that reports.
