password: attrs[:password] || "supersecret"

video
end
end
In the above code from the book, the tests calls user_fixture twice. There is a unique_index for the username in the migration for the user.
defmodule Rumbl.Repo.Migrations.CreateUsers do
use Ecto.Migration
def change do
create table(:users) do
add :name, :string
add :username, :string, null: false
add :password_hash, :string
timestamps()
end
create unique_index(:users, [:username])
end
end
so when a username: “max” is attempted to be created for the second time an error is returned. The book says all the tests pass with the command mix test test/rumbl_web --only login_as so I’m wondering if I’m missing something, especially in the @tag implementation.
mbp:rumbl pyop$ mix test test/rumbl_web --only login_as
