I'm no longer heavily involved in maintaining this, but am willing to hand over this to community if people are still using it in some way. File an issue if you're interested in doing so.
These samples are preconstructed to demonstrate how each test framework included can be used along with a demo app in App Center Test.
Primary documentation for App Center Test is available here: https://docs.microsoft.com/en-us/appcenter/test-cloud/
No matter which test framework you are using, to run UI Tests in App Center, you must generate a prototype upload commandline in one of the systems using the wizard. This command line requires modifications in order to be executed, which the test framework-specific upload scripts demonstrate for basic usage.
appcenter test run appium --app "kegr/ReadmeDemo" --devices "kegr/top-4" --app-path pathToFile.apk --test-series "master" --locale "en_US" --build-dir target/upload
