It depends, if you need to support old Edge (Spartan) you'll need to use one of the freely available virtual machines from Microsoft instead of just installing the browser.

Not a huge pain either, but given that there's still people out there that need to test on ie11 I wouldn't be surprised if Edge has befallen the same faith.

Old Edge is essentially gone, since it autoupdated to New Edge. New Edge has Linux and Mac builds.
