Where we are right now is that we have a branch that should be php7-compliant but some bits are more thoroughly tested than others. When the changes were done I and others ran every one to prove the old code produced a deprecated notice and that the changed code didn't. (Plus the change to evaluation order - harder to spot).
However the branch we now have has been rebuilt manually and it's possible it doesn't include every single code change that it should so the more eyes we can get on it, the better.
We pretty much need to run every bit of code that there is in a php7 environment and check that it behaves as expected. If you have enough time to try to do that as well, including running the install - great, let me know and I can set you up with a folder and database to do it in.
If you have less time but still want to help I can give access to a system that's already set up, and it would be great if you can do one of the things that are less easy... if you use a payment method that's not cash, cheque or paypal standard it probably hasn't been tested all the way through placing an order. Most need a merchant account to be able to test them, some even to install.
So even if all you have time for is to log into admin on the test system and set up a payment method, then create a test user and place a test order, that would still be a really big help.
If you've time for a poke around to see if you can break anything while you're there, that'll be even better!
Just pm me and I'll send you an admin user.
