fish-tank 
The test framework for fish, write some tests and find out how they behave in the tank.
Installation
git clone git://github.com/terlar/fish-tank.git
cd fish-tank
make installConfiguration
For now there is only one piece of configuration:
set -U tank_reporter dots for simple output (default).
set -U tank_reporter spec for detailed output.
Examples
A simple approach using a test helper.
It could be even simpler if you assume users have fish-tank installed, but it is good practice to make sure.
You could of course also skip the helper in simple cases, but it is recommended when having multiple tests to avoid duplication.
helper.fish
set -l fish_tank /usr/local/share/fish-tank/tank.fish
if not test -e $fish_tank
echo 'error: fish-tank is required to run these tests (https://github.com/terlar/fish-tank)'
exit 1
