测试输出

Question

我有以下凤凰申请：

mix phoenix.new my_app --database mysql
cd my_app
mix ecto.create
mix phoenix.gen.html User users name:string
mix ecto.migrate

现在mix test没有遇到问题。

如果我将test/controllers/user_controller_test.exs更改为期望“某些内容”而不是show中的“显示用户”，因为@valid_attrs %{name: "some content"}而应该存在，而不是测试失败。为什么会这样？ user#show页面上应该包含“部分内容”。当我在development模式下在浏览器中手动尝试时，它就有了。

错误在哪里？我该如何解决？

测试/控制器/ user_controller_test.exs

defmodule MyApp.UserControllerTest do
  use MyApp.ConnCase

  alias MyApp.User
  @valid_attrs %{name: "some content"}
  @invalid_attrs %{}

  [...]

  test "shows chosen resource", %{conn: conn} do
    user = Repo.insert! %User{}
    conn = get conn, user_path(conn, :show, user)
    assert html_response(conn, 200) =~ "some content"
  end

  [...]

测试输出

该行

user = Repo.insert! %User{}

将所有字段设置为nil的用户插入。

如果您要使用@valid_attrs创建用户，请将该行更改为：

user = Repo.insert! User.changeset(%User{}, @valid_attrs)

在用户#show中测试“某些内容”
