An adapter that sends emails as messages to the current process.

This is meant to be used during tests and works with the assertions found in the Swoosh.TestAssertions module.

Example

# config/test.exs
config :sample, Sample.Mailer,
  adapter: Swoosh.Adapters.Test

# lib/sample/mailer.ex
defmodule Sample.Mailer do
  use Swoosh.Mailer, otp_app: :sample
end
