Fusion repositories for Fedora pre-release are available
As you can see on home page of RPM Fusion, the repositories for Alpha and Beta version are enable. Fedora pre-release repositories are available, but they’re just not yet browsable with online on RPM Fusion website.
So, from site, RPM Fusion provides software that the Fedora Project or Red Hat doesn’t want to ship. That software is provided as precompiled RPMs for all current Fedora versions and Red Hat Enterprise Linux 5 and 6; you can use the RPM Fusion repositories with tools like yum and PackageKit. RPM Fusion is a merger of Dribble, Freshrpms, and Livna; our goal is to simplify end-user experience by grouping as much add-on software as possible in a single location.

How to enable Fusion repositories for Fedora 24 Beta
When testing Fedora pre-release, keep in mind that RPM Fusion is maintained by volunteers and maybe has still some issues.
Actually, these are the testing repos for Fedora 24:
sudo dnf install --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-24.noarch.rpm
sudo dnf install --nogpgcheck http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-24.noarch.rpm
Sometimes issues happened, also for RPM Fusion
So, if you experienced any issue with the RPM Fusion for the Fedora 24 pre-releases, take a look at this Wiki on the AskFedora knowledge. In alternative, you could find useful this repositories: UnitedRPMs repository for Fedora.
I’m looking also to keep my repository too. But it needs long time, a very long time.
Cheers!
