AAA04: expected 1 blank line before Assert block, found none

For tests that have an Assert block, there must be a blank line between the Act and Assert blocks, but Flake8-AAA could not find one.

This blank line creates separation between the action and the assertions and makes the Act block easy to spot.

As with rule AAA03, this rule works best with E303 enabled.

Resolution

Add a blank line before the Assert block.
