Use Database Transactions for running tests

[cycomachead]

Database transactions are a bit faster than committing and re-deleting everything all the time.

They also enable you to have a consistent starting point for every test, which is sometimes useful.

This should be easy, but of course, it's not...

-- Use database transactions for speed
local busted = require('busted')

busted.before_each(function()
    db.query('BEGIN')
end)
busted.after_each(function()
    db.query('ROLLBACK')
end)

When this is done the transactions are executed properly, but things inside the request method fail.  ¯_(ツ)_/¯
