It's really strange that the trybots happily ran these tests anyway :-/
E.g.

https://build.chromium.org/p/tryserver.webrtc/builders/mac_baremetal/builds/1...

-      testonly = true
-      sources = [
-        "test/audio_device_test_api.cc",
-        "test/audio_device_test_defines.h",
-      ]
-      deps = [
-        ":audio_device",
-        "../..:webrtc_common",
-        "../../system_wrappers",
-        "../../test:test_main",
-        "../../test:test_support",
-        "../rtp_rtcp",

-      ]
-      public_configs = [ ":audio_device_config" ]
-    }
-  }
 }
