仅为测试项目生成代码覆盖率

Question

我有一个项目（比如A.csproj）和一个测试项目（比如T.csproj）。

T 有 coverlet.msbuild 和 Microsoft.NET.Test.Sdk 作为 nuget 引用。 T 有一个不包含包含/排除路径的 .runsettings 文件（包括所有程序集，不排除）。

执行dotnet test T.csproj /p:CollectCoverage=true /p:IncludeTestAssembly=true /p:CoverletOutputFormat=cobertura --settings:".runsettings"，只会为测试项目生成覆盖率：

+--------------------+--------+--------+--------+
| 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% |
+---------+--------+--------+--------+

如果我删除/p:IncludeTestAssembly=true，只会生成一个空报告：

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

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

即使我通过 cmdline 本身指定包含所有模块，也会发生同样的情况：dotnet test T.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:Include="[*]*"

尝试这个：

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

$>src> reportgenerator -reports:**/coverage.opencover.xml -targetdir:Tests
esultsWebResult

$>src> Tests
