How to test LiveView behind AshAuthentication?
I have some LiveViews that require an authenticated user to access (AshAuthentication). How do I simulate login for the user?
I saw that there are a few tests in the AshHQ repo and I did try to copy all of the relevant stuff, but I still can't get it to work. Here's what I have so far:
defmodule MyAppWeb.BookLiveTest do
use MyAppWeb.ConnCase
import Phoenix.LiveViewTest
describe "with existing books" do
setup %{conn: conn} do
result = register_and_log_in_user(%{conn: conn})
book = book_fixture(result[:user], %{name: "Test Book"})
%{
conn: result[:conn],
user: result[:user],
book: book
}
end
test "lists all books", %{conn: conn, book: book} do
{:ok, _index_live, html} = live(conn, ~p"/books")
assert html =~ "Listing Books"
assert html =~ book.name
end
end
end
defmodule MyAppWeb.BookLiveTest do
use MyAppWeb.ConnCase
import Phoenix.LiveViewTest
describe "with existing books" do
setup %{conn: conn} do
result = register_and_log_in_user(%{conn: conn})
book = book_fixture(result[:user], %{name: "Test Book"})
%{
conn: result[:conn],
user: result[:user],
book: book
}
end
test "lists all books", %{conn: conn, book: book} do
{:ok, _index_live, html} = live(conn, ~p"/books")
assert html =~ "Listing Books"
assert html =~ book.name
end
end
end
defmodule MyAppWeb.LoginTestHelpers do
alias MyApp.AccountsFixtures
def register_and_log_in_user(%{conn: conn}) do
user = AccountsFixtures.user_fixture()
%{conn: log_in_user(conn, user), user: user}
end
def register_user(_context) do
%{
user: AccountsFixtures.user_fixture()
}
end
def log_in_user(conn, user) do
conn
|> Phoenix.ConnTest.init_test_session(%{})
|> Plug.Conn.put_session(:user_token, user.__metadata__.token)
end
end
defmodule MyAppWeb.LoginTestHelpers do
alias MyApp.AccountsFixtures
def register_and_log_in_user(%{conn: conn}) do
user = AccountsFixtures.user_fixture()
%{conn: log_in_user(conn, user), user: user}
end
def register_user(_context) do
%{
user: AccountsFixtures.user_fixture()
}
end
def log_in_user(conn, user) do
conn
|> Phoenix.ConnTest.init_test_session(%{})
|> Plug.Conn.put_session(:user_token, user.__metadata__.token)
end
end

I hit the character limit in my initial post. This is the continuation:
I'm getting this error when running the test:

password,
password,

)
receive do
{:email, _} -> :ok
after

end
user
end
end

Hey @Terryble , replace
Plug.Conn.put_session(:user_token, user.__metadata__.token) with AshAuthentication.Phoenix.Plug.store_in_session(user) in your log_in_user helperHoly crap, that worked! I wonder why the AshHQ repo didn't have to do that to make it work on the tests.
