# Testing The configuration you likely want to add to your `config/test.exs` is: ```elixir # 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`. ```elixir # 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`. ```elixir # config/test.exs config :ash, :missed_notifications, :ignore ```
