### Execute Tests on Multiple resolutions

If you want to execute visual regression tests on multiple resolutions, need to add capability `resolution` in capabilities option.

let capabilities = { ... resolution = "1920x1080"; ... }

Few common resolutions are
- 1024x768
- 1280x800
- 1600x1200
- 1920x1080
- 2560x1440

#### Run Test on `1024x768` resolution 

$ node custom-resolutions.js 1024x768
