The problem of multiple roles * multiple permissions (per role) can
make this explode quite a bit. There is a relatively new feature in
cucumber that lets you express things in a tabular format in addition
to scenarios (think FIT, but plain text). So you can do this:
Scenario: roles 3 and up can create a user
Given I am in the 'role 3' role
When I try to create a new user
Then I am allowed
| role | action | response |
| role 1 | create a new user | denied |
| role 2 | create a new user | denied |
| role 3 | create a new user | allowed |
| role 4 | create a new user | allowed |
| role 5 | create a new user | allowed |
(that looks right if you view in a monospace font)
For my money (even thought it's free), this is the perfect situation
for this format, as it allows you to express a number of cases/rules
in a clear succinct way.
