mix.test cleans the test database, but it is not working.
It may be because I was playing around with making a
users schema, but didn't want to use what I made so I got rid of it. I then started over and made a new schema for users which was different from the first.
You can access the test database by using
MIX_ENV=test followed by a command such as
mix do ecto.drop,
mix ecto.reset or
MIX_ENV=test mix ecto.reset
mix ecto.drop --repo Order.Repo
To find out more about an Ecto task, use
mix help <task>
