Install 'Masquerade role' and create a dedicated role for it

Andy said at a PG that Brighton is using this successfully - covers the bases of features being visible and useable by specific roles

Masquerade was previously suggested https://www.drupal.org/project/masquerade but it's not covered by the Drupal security policy

I'd consider Masqurade role instead as its a better fit for what actully needs testing (user roles and role combinations) and is a bit more lightweight.

Totally works for me, thanks @andybroomfield

I'll update the card
