Can't get it to work · FortuneN/FineCodeCoverage · Discussion #128

(I thought I already posted this question, but now can't find it. Must have dreamt it).

We have 275 unit tests. They run fine.

Here's the UnitTests.csproj:

<Project Sdk="Microsoft.NET.Sdk">
 <PropertyGroup>
 <TargetFramework>net5.0</TargetFramework>
 <IsPackable>false</IsPackable>
 </PropertyGroup>
 <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
 <DefineConstants>TRACE</DefineConstants>
 </PropertyGroup>
 <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
 <DefineConstants>TRACE;DEBUG_IDISPOSABLE</DefineConstants>
 </PropertyGroup>
 <ItemGroup>
 <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.9.4" />
 <PackageReference Include="System.Collections" Version="4.3.0" />

 </ItemGroup>
 <ItemGroup>
 <ProjectReference Include="..\Terminal.Gui\Terminal.Gui.csproj" />
 <ProjectReference Include="..\UICatalog\UICatalog.csproj" />
 </ItemGroup>
</Project>

I've installed the Fine Code Coverage extension. But when I build, I don't get any results:

This is even after I ran dotnet test /p:CollectCoverage=true manually:

This is because

Fine Code Coverage works by reacting to the visual studio test explorer, providing coverage from each test project containing tests that you have selected to run

I restarted VS and tried again. The FCC output is now there.

However, it's still not actually working:

I had the same results until

From the readme

<PropertyGroup>
	<UseDataCollector/>
</PropertyGroup>

Coverlet has different "drivers". Fine Code Coverage has in the past only used the coverlet console driver. This has some issues associated with it. It is now possible to switch to the Data Collector driver. This is the better driver but cannot be used for all projects. For now this is opt in. In the future Fine Code Coverage will determine the appropriate driver. Please consult coverlet docs for version support. ** Note that it is unnecessary to add the nuget coverlet.collector package as FCC internally supplies coverlet.collector 3.0.3** Fine Code Coverage will use the Data Collector driver under two circumstances :

You are testing with runsettings that contains the coverlet collector ( and not disabled)

You set the UseDataCollector project property
