Am trying to generate a test coverage in the Circle CI with this file config.yml, but the build fails and it says No connected devices.
Below is the error generated on Circle CI :

And according to what I read Circle CI doesn't support Emulators currently.

Below is my config.yml file :

version: 2

It's suggested to use Buddybuild for emulators over Circle CI

Buddybuild has been able to boot an emulator just fine, but the nature of my project doesn't work well with them. I'd suggest that if you aren't building a library, try buddybuild
