[rhyspang]

The WDA server starts with no error, status api return

{
  "value" : {
    "state" : "success",
    "os" : {
      "name" : "iOS",
      "version" : "12.1.2"
    },
    "ios" : {
      "simulatorVersion" : "12.1.2",
      "ip" : "192.168.199.117"
    },
    "build" : {
      "time" : "Jul 23 2019 00:02:53"
    }
  },
  "sessionId" : "0CEA2D34-9DBA-4020-9E3E-7683D2D4AEEA",
  "status" : 0
}

  "status" : 1
}
