How can I run a iOS App which has been built on MacOSX using the `Test` build containing `XCTest` unit tests from Linux to a iOS device

Question

I have been researching this for the past few weeks and working to try to see if how it is possible to setup https://github.com/facebook/WebDriverAgent and in particular XCTest's to be able to be deployed and ran in test mode from Linux.

At this point I can use xcodebuild build-for-testing or test which will build the WDA App (XCTest unit tests) on MacOSX and then deploy it onto the phone and run it as Test. This allows the XCTest libraries to be loaded and then allows interaction between WDA and automation on the phone via the XCTest framework.

I am wondering if there is some way to either extend ideviceinstaller, libimobiledevice or ios-deploy or some other solution to support pushing the Test build to a real iOS device from Linux.

• How can I run a iOS App which has been built on MacOSX using the Test build containing XCTest unit tests from Linux to a iOS device?

I have seen commercial products which provide this so there must be a way to do this but I am currently stuck trying to determine how to do this.
