# Testing With Postgres
|
|
|
|
When using AshPostgres resources in tests, you will likely want to include use a test case similar to the following. This will ensure that your repo runs everything in a transaction.
|
|
|
|
```elixir
|
|
defmodule MyApp.DataCase do
|
|
@moduledoc """
|
|
This module defines the setup for tests requiring
|
|
access to the application's data layer.
|
|
|
|
You may define functions here to be used as helpers in
|
|
your tests.
|
|
|
|
Finally, if the test case interacts with the database,
|
|
we enable the SQL sandbox, so changes done to the database
|
|
are reverted at the end of every test. If you are using
|
|
PostgreSQL, you can even run database tests asynchronously
|
|
by setting `use AshHq.DataCase, async: true`, although
|
|
this option is not recommended for other databases.
|
|
"""
|
|
|
|
use ExUnit.CaseTemplate
|
|
|
|
using do
|
|
quote do
|
|
alias MyApp.Repo
|
|
|
|
import Ecto
|
|
import Ecto.Changeset
|
|
import Ecto.Query
|
|
import MyApp.DataCase
|
|
end
|
|
end
|
|
|
|
setup tags do
|
|
pid = Ecto.Adapters.SQL.Sandbox.start_owner!(MyApp.Repo, shared: not tags[:async])
|
|
on_exit(fn -> Ecto.Adapters.SQL.Sandbox.stop_owner(pid) end)
|
|
:ok
|
|
end
|
|
end
|
|
```
|
|
|
|
This should be coupled with to make sure that Ash does not spawn any tasks.
|
|
|
|
```elixir
|
|
config :ash, :disable_async?, true
|
|
```
