Nativescript-Dev-Appium Setup - appium

Question

I am trying to implement nativescript-dev-appium in an existing nativescript-angular project and am having a lot of trouble getting the plugin configured.
The simulator appears to be found but the run fails in the before all and after all hooks because it appears to not have a device instance.
walrus:demo-appium niirds$ npm run e2e -- --runType sim.iPhoneX --verbose

Here is the simulator capability, provided by the installation:
"sim.iPhoneX": {
"platformName": "iOS",
"platformVersion": "/12*/",
"deviceName": "iPhone X",
"noReset": false,
"fullReset": false,
"app": ""
},
I have xcode 10.2 installed, and here is the package.json if that helps.

Steps to reproduce:
1. create sample nativescript-angular app--i used the tab navigation one for this test.
2. install nativescript-dev-appium: npm i -D nativescript-dev-appium
3. install other dependencies https://docs.nativescript.org/angular/tooling/testing/end-to-end-testing/overview#environment-setup
4. build app: tns build <platform>
5. run test: `npm run e2e -- --runType
i have been trying to get this to work on iOS for now.
Any help will be greatly appreciated!

Answer 1

I think that for some reason the device type that device controller has returned type: 'watch' is not correct.
I suggest you change the config to something like:
"sim.iPhoneX": {
"platformName": "iOS",
"platformVersion": "12.2",
"deviceName": "iPhone X",
"noReset": false,
"fullReset": false,
"app": ""
},
or simply try it with the --ignoreDeviceController option.
