See screenshots for defining a local testing server:

Site > New Site...

The best way I can think of to test your site across multiple devices, is to:

1. Install a local testing server like the free XAMPP.
2. You then place your site's root folder within the XAMPP installation's htdocs folder.
3. From there you run XAMPP as Administrator
4. Start the Apache service
5. Open a command prompt and type in "ipconfig" and hit Enter (no quotes) to obtain your Local IP Address
6. On any device connected to your local network, enter your machine's local IP address followed by the site root folder name (ex: 123.4.5.6/MySite).

From there on out, any change you make that's saved in the site will only require a refresh of the browser for the devices connected to your local network to see it.

When that feature was deprecated the only remaining ways to preview your site were the following: https://helpx.adobe.com/dreamweaver/using/previewing-pages.html . For the most part testing on phones should be able to be done in your browser via the device preview, but it's always recommended to test in some live devices or use apps like Simulator on a Mac to preview on an iPad/iPhone.
