Code coverage gets generated only for Tests project

Question

I've got a project (say A.csproj) and a tests project (say T.csproj).

T has coverlet.msbuild and Microsoft.NET.Test.Sdk as nuget references. T has a .runsettings file with no include include/exclude paths (all assemblies included, non excluded).

Doing dotnet test T.csproj /p:CollectCoverage=true /p:IncludeTestAssembly=true /p:CoverletOutputFormat=cobertura --settings:".runsettings", results in only coverage being generated for the tests project:

+--------------------+--------+--------+--------+
| Module             | Line   | Branch | Method |
+--------------------+--------+--------+--------+
| T                  | 98.87% | 100%   | 96.29% |
+--------------------+--------+--------+--------+

+---------+--------+--------+--------+
|         | Line   | Branch | Method |
+---------+--------+--------+--------+
| Total   | 98.87% | 100%   | 96.29% |
+---------+--------+--------+--------+
| Average | 98.87% | 100%   | 96.29% |
+---------+--------+--------+--------+

If I drop /p:IncludeTestAssembly=true, there's only an empty report generated:

| Module | Line | Branch | Method |
+--------+------+--------+--------+

+---------+------+--------+--------+
|         | Line | Branch | Method |
+---------+------+--------+--------+
| Total   | 0%   | 0%     | 0%     |
+---------+------+--------+--------+
| Average | 0%   | 0%     | 0%     |
+---------+------+--------+--------+

The same happens even when I specify for inclusion for all modules via the cmdline itself: dotnet test T.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:Include="[*]*"

is it possible to put content of `T.csproj` – CodingMytra Jul 07 '22 at 17:45 — CodingMytra, Jul 07 '22 at 17:45

Try this:

$>src> dotnet test <YOUR_PROJECT>.sln --no-build /p:CollectCoverage=true /p:CoverletOutput=..\results\coverage /p:MergeWith=..\results\coverage.json /p:CoverletOutputFormat=opencover

$>src> reportgenerator -reports:**/coverage.opencover.xml -targetdir:Tests\results\WebResult

$>src> Tests\results\WebResult\index.html
