Chrome has an mobile emulator built in, accessible through the inspector: http://www.marksenff.com/front-end/you-already-have-a-retina-screen-emulator/

Still, always test on actual devices as well. Tools like Prepros have a built-in web server that enables you to access your local site on a phone or tablet or anything using your wifi network.
