In order to build libraries and tests for iOS or tvOS you need recent version of XCode installed (e.g. 11.3 or higher).
Build Libraries for iOS Simulator:
./build.sh mono+libs -os iOSSimulator -arch x64
Run tests one by one for each test suite on a simulator:
./build.sh libs.tests -os iOSSimulator -arch x64 -test
In order to run the tests on a device:
- Set the os to
iOSinstead ofiOSSimulator - Specify
DevTeamProvisioning(see developer.apple.com/account/#/membership, scroll down toTeam ID):
./build.sh libs.tests -os iOS -arch x64 -test /p:DevTeamProvisioning=H1A2B3C4D5
AppleAppBuilder generates temp Xcode projects you can manually open and resolve provisioning issues there using native UI and deploy to your devices.
- The following shows how to run tests for a specific library:
./dotnet.sh build src/libraries/System.Numerics.Vectors/tests /t:Test /p:TargetOS=iOS /p:TargetArchitecture=x64
iOS/tvOS *.app (or *.ipa) is basically a simple ObjC app that inits the Mono Runtime. This Mono Runtime starts a simple xunit test
runner called XHarness.TestRunner (see https://github.com/dotnet/xharness) which runs tests for all *.Tests.dll libs in the bundle. There is also XHarness.CLI tool to deploy *.app and *.ipa to a target (device or simulator) and listens for logs via network sockets.
- Most of the test suites crash on devices due to #35674
- Simulator uses JIT mode only at the moment (to be extended with FullAOT and Interpreter)
- Interpreter is not enabled yet.
