@spec inertia_component(Plug.Conn.t()) :: String.t() | nil

Fetches the Inertia component (if applicable) for the current request.

Example

use MyAppWeb.ConnCase

import Inertia.Testing

describe "GET /" do
  test "renders the home page", %{conn: conn} do
    conn = get("/")
    assert inertia_component(conn) == "Home"
  end
end

@spec inertia_errors(Plug.Conn.t()) :: map()

Fetches the Inertia errors (if applicable) for the current request.

If there are errors available in the current page props, they will be returned. Otherwise, errors that have been stored in the session will be retrieved.

Example

use MyAppWeb.ConnCase

import Inertia.Testing

describe "POST /users" do
  test "fails when name empty", %{conn: conn} do
    conn = post("/users", %{"name" => ""})

    assert %{user: %{id: 1}} = inertia_props(conn)
    assert redirected_to(conn) == ~p"/users"
    assert inertia_errors(conn) == %{"name" => "can't be blank"}
  end
end

@spec inertia_props(Plug.Conn.t()) :: map() | nil

Fetches the Inertia props (if applicable) for the current request.

Example

use MyAppWeb.ConnCase

import Inertia.Testing

describe "GET /" do
  test "renders the home page", %{conn: conn} do
    conn = get("/")
    assert %{user: %{id: 1}} = inertia_props(conn)
  end
end
