Status
======
The Hspec tests are very superficial and pretty much the bare mininmum
that needs to be tested. The property tests are very thorough, but
could be made even more thorough.
Future
======
The property testing strategy is to define a denotation for SelectArrs
and to show that the denotation of two SelectArrs combined with an
operation is the same as using the operation to combine the
denotations. The denotation that we will choose is roughly `Kleisli
[]` but we have to do IO operations over a Postgres connection so it's
slightly different in practice in a way that doesn't impinge on what I
am about to say.
For example, using brackets "[.]" to stand for denotation, we want to
ensure the property
* [f <<< g] = [f] <<< [g]
That is, running `f <<< g` on some input should be the same as running
`g` on the input, followed by running `f` on the output of `g`.
Likewise we want to ensure typeclass-general properties like
* [id] = id
* [f <*> g] = [f] <*> [g]
as well as Postgres-specific properties like
* [restrict] = guard
* [limit n q] = arr (take n) . [q]
The property tests are not written quite as neatly as this because
there is a lot of scaffolding to make things line up. It's probably
possible to simplify the property tests though.
