代码覆盖率仅为测试项目生成

Question

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

T具有CCD_ 3和CCD_。T有一个.runsettings文件，该文件没有包含-包含/排除路径(包括所有程序集，未排除所有程序集)。

执行dotnet test T.csproj /p:CollectCoverage=true /p:IncludeTestAssembly=true /p:CoverletOutputFormat=cobertura --settings:".runsettings"，结果仅为测试项目生成覆盖范围：

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

如果我丢弃/p:IncludeTestAssembly=true，则只生成一个空报告：

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

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

试试这个：

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

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

$>src> TestsresultsWebResultindex.html
