[英]Phoenix: How to test controller actions from the console?
I have created a new controller action and I would like to test it from the console to make sure it works.我创建了一个新的控制器操作,我想从控制台测试它以确保它正常工作。
How can I execute the action after running iex -S mix phx.server
in the terminal?在终端中运行
iex -S mix phx.server
后如何执行操作? It seems to me that in order to do this, I need to create a conn
struct as well as a user
struct (since I am using Guardian).在我看来,为了做到这一点,我需要创建一个
conn
结构以及一个user
结构(因为我使用的是 Guardian)。
My controller code looks like this:我的控制器代码如下所示:
defmodule HelloWeb.AssetController do
use HelloWeb, :controller
use Guardian.Phoenix.Controller
action_fallback HelloWeb.FallbackController
def new_action(conn, %{"id" => id}, user, _claims) do
# Stuff I want to test
end
# Other actions omitted
end
How can I test new_action
from IEx?如何从 IEx 测试
new_action
?
You can use phoenix test helpers to achieve something like what's done in the ExUnit tests in iex
:您可以使用 phoenix 测试助手来实现类似于在
iex
中的 ExUnit 测试中iex
:
iex(22)> conn = Phoenix.ConnTest.build_conn() |>
...(22)> Phoenix.Controller.put_view(HelloWeb.AssetView)
%Plug.Conn{...}
# This assumes you have at least one user created in the dev database
iex(23)> [user | _] = HelloWeb.Schemas.User |> HelloWeb.Repo.all
iex(23)> HelloWeb.AssetController.new_action(conn, %{"id" => some_id}, user, [])
# You can inspect this conn to see if what's rendered is OK
%Plug.Conn{...}
