Testing

Take a look at the how-to guide for a practical look at writing tests

The configuration you likely want to add to your config/test.exs is:

# config/test.exs
config :ash, :disable_async?, true
config :ash, :missed_notifications, :ignore

Each option is explained in more detail below.

Async tests

The first thing you will likely want to do, especially if you are using AshPostgres, is to add the following config to your config/test.exs.

# config/test.exs
config :ash, :disable_async?, true

This ensures that Ash does not spawn tasks when executing your requests, which is necessary for doing transactional tests with AshPostgres.

Missed notifications

If you are using Ecto's transactional features to ensure that your tests all run in a transaction, Ash will detect that it had notifications to send (if you have any notifiers set up) but couldn't because it was still in a transaction. The default behavior when notifications are missed is to warn. However, this can get pretty noisy in tests. So we suggest adding the following config to your config/test.exs.

# config/test.exs
config :ash, :missed_notifications, :ignore
