Unit testing 如何对Jenkins管道中的dotnet核心web应用程序进行单元测试？

我试图在构建的dotnet core web应用程序上运行测试，但无法执行，因为我尝试的方法会出现如下所示的错误

我使用的脚本是

stage ('Restore PACKAGES') {
steps {
bat "dotnet restore "
echo 'packages are restored'
}
}
stage('Clean') {
steps {
bat 'dotnet clean'
echo 'clean is done'
}
}
stage('Build') {
steps {
bat 'dotnet build --configuration Release'
echo 'build is done'
}
}
stage('Pack') {
steps {
bat 'dotnet pack --no-build --output nupkgs'
echo 'nupkgs package is created'
}
}
stage('testing') {
steps {
  bat returnStatus: true, script: "\"C:/Program Files/dotnet/dotnet.exe\" test \"${workspace}/dotnetapp.sln\" --logger \"trx;LogFileName=unit_tests.xml\" --no-build"
    step([$class: 'MSTestPublisher', testResultsFile:"**/unit_tests.xml", failOnError: true, keepLongStdio: true])

}
  }

那么我如何为构建应用程序进行测试呢？除了这个我还有别的办法吗？我参考了此解决方案，任何建议和文章都会非常有用，谢谢。

问题是由于解决方案中缺少测试项目造成的。

为什么不执行

脚本：“dotnet test”

或

脚本：“dotnet test dotnetapp.csproj”

？@omajid我尝试过使用脚本：“dotnet test dotnetapp.csproj”我得到的错误是C:\Program Files（x86）\Jenkins\workspace\Jenkins Pipeline>dotnet test dotnetapp.csproj MSBUILD:错误MSB1009:项目文件不存在。这非常令人惊讶。还原行显示它存在：

对于C:\Program Files（x86）\Jenkins\workspace\Jenkins Pipeline\dotnetapp\dotnetapp.csproj，还原在75.52毫秒内完成。

。有什么要删除它吗？没有，我在还原bat后执行了以下步骤“dotnet clean”bat“dotnet build--配置发布版“bat”dotnet pack--没有构建--输出nupkgs”，然后我尝试使用dotnet test dotnetapp.csproj该项目位于dotnetapp子目录中。试着运行

dotnet测试~/dotnetapp/dotnetapp.csproj

yaa我想出来了，我构建了测试项目，然后它就工作了，谢谢
