the script that I used is this

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])

}
  }

so how can I do testing for the build app ? are there any other way which I can try than this ? I refered this solution Jenkins integration for dotnet test any suggestion and articles will be very helpful thanks.

Why are you not doing `script: "dotnet test"` or `script: "dotnet test dotnetapp.csproj"`? — omajid, Oct 18 '18 at 05:16
@omajid I did try using script: "dotnet test dotnetapp.csproj" I get error as C:\Program Files (x86)\Jenkins\workspace\jenkins Pipeline>dotnet test dotnetapp.csproj MSBUILD : error MSB1009: Project file does not exist. — deepinside, Oct 18 '18 at 05:30
That's very surprising. The restore line says it exists: `Restore completed in 75.52 ms for C:\Program Files (x86)\Jenkins\workspace\jenkins Pipeline\dotnetapp\dotnetapp.csproj.`. Is something deleting it? — omajid, Oct 18 '18 at 05:37
no I did following stages after restore bat 'dotnet clean'bat 'dotnet build --configuration Release'bat 'dotnet pack --no-build --output nupkgs' then I tried using dotnet test dotnetapp.csproj — deepinside, Oct 18 '18 at 05:50
This project is located in dotnetapp subdirectory. Try running `dotnet test ~/dotnetapp/dotnetapp.csproj` — Krzysztof Błażełek, Oct 18 '18 at 06:33
@KrzysztofBłażełek ok I used dotnet test ./mathcalci/mathcalci.csproj and duild I got error as following C:\Program Files (x86)\Jenkins\workspace\jenkins Pipeline>dotnet test ./dotnetapp/dotnetapp.csproj Build started, please wait...

Try this: `dotnet test ./dotnetapp/dotnetapp.csproj --no-build --no-restore` — Krzysztof Błażełek, Oct 18 '18 at 07:00
@KrzysztofBłażełek still I get the same error as above Make sure test project has a nuget reference of package "Microsoft.NET.Test.Sdk" and framework version settings are appropriate. — deepinside, Oct 18 '18 at 07:07
It doesn't look like a test project to me. What is the project that contains your tests? — Krzysztof Błażełek, Oct 18 '18 at 08:00
this is the content of dotnetapp.csproj file, do you mean dotnetapp.dll file? — deepinside, Oct 18 '18 at 08:28

The problem was caused by lack of test project in the solution.
