NUnit Tests on Jenkins with Appium Server


I am just trying to get my NUnit tests, written in Visual Studio with C#, running on Jenkins with the help of Appium Server. As far I can already start the server like

#start appium server
appium --address --chromedriver-port 9516 --bootstrap-port 4725 --no-reset --local-timezone

and I can install my apk file on real device attached to Jenkins like

# Install apk and overwrite existing app (-r)
adb install -r ScoolioApp/app/build/outputs/apk/release/app-release.apk

Now I need help. How can I run my NUnit tests with this setup?

Thanks in advance
