Setup Test skipped: Not enough suites found to execute

Hi,

I tired to test a simple app with xctest framework on Device Farm. It shows "Setup Test skipped: Not enough suites found to execute
". but the app did have some tests.

The app source code: https://github.com/lloydsheng/DeviceFarmTest
The job link: https://us-west-2.console.aws.amazon.com/devicefarm/home?region=us-east-1#/projects/fe31921c-c291-46de-9c8f-620a112fe648/runs/43dc3d5a-4140-4be7-a627-98f3de086164/jobs/00000

The development environment:
Xcode 12.2
macOS 10.15.7
