selector body:noclip error

v1.2.1

In my scenario. I am using the body:noclip to invoke a full screen capture instead of casper.captureSelector(), thus below is my setting.
...
"selectors": [
"body:noclip"
],
...
npm run test > fails at 'compare' as it could not find the 0_bodynoclip_0_phone.png as there is no such file in my backstop_data. Is my scenario setting for body:noclip correct in order to capture a full screen? How do I resolve this?
