Ruby on rails RoR-测试错误-预期<&引用；类别/新&燃气轮机；但是使用<；[]>；

我的应用程序测试有问题。它已经存在太久了，我甚至想知道，为什么我要测试它（因为在测试之外，它工作得很完美！）

以下是错误：

$rake测试 运行选项：--seed 1855

`#运行：

失败： CreateCategoriesTest#测试(无效)类别(提交)结果(失败) [/Users/user/Documents/ruby_project/rails_projects/alpha blog/test/integration/create_categories_test.rb:17]： 预期但渲染为

以0.638134s、18.8048次运行/秒、25.0731次断言/秒的速度完成。12分， 16次断言，2次失败，0次错误，0次跳过

测试结果如下所示：

require 'test_helper'

class CreateCategoriesTest < ActionDispatch::IntegrationTest

  test "get new category form and create category" do
    get new_category_path
    assert_template 'categories/new'
    assert_difference 'Category.count', 1 do
    post categories_path, params: { category: {name: "sports"}}
    follow_redirect!
    end
    assert_template 'categories/index'
    assert_match 'sports', response.body
  end

  test "invalid category submission results in failure" do
    get new_category_path
    assert_template 'categories/new'
    assert_no_difference 'Category.count' do
    post categories_path, params: { category: {name: " "}}
    end
    assert_template 'categories/new'
    assert_select 'h3.panel-title'
    assert_select 'div.panel-body'
  end
end

至于“无效类别提交导致失败”测试I，替换为：

post categories_path, category: {name: " "}

在我限制应用程序（在控制器中）的使用之前，它已经起作用了：

有人知道发生了什么事吗？提前谢谢

好的，我已经得到了我问题的答案。愚蠢的我，我没有通过这些测试的用户，而且，很明显，由于需要用户，测试无法再正确执行

下面是测试助手文件中的更正：

require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
  def sign_in_as(user, password)
    post login_path, params: { session: {email: user.email, password: password}}
  end
end

对于创建类别测试：

require 'test_helper'

class CreateCategoriesTest < ActionDispatch::IntegrationTest

    def setup
        @user = User.create(username: "John", email: "john@example.com", password: "password", admin: true)
    end

  test "get new category form and create category" do
    sign_in_as(@user, "password")
    get new_category_path
    assert_template 'categories/new'
    assert_difference 'Category.count', 1 do
    post categories_path, params: { category: {name: "sports"}}
    follow_redirect!
    end
    assert_template 'categories/index'
    assert_match 'sports', response.body
  end

  test "invalid category submission results in failure" do
    sign_in_as(@user, "password")
    get new_category_path
    assert_template 'categories/new'
    assert_no_difference 'Category.count' do
    post categories_path, params: { category: {name: " "}}
    end
    assert_template 'categories/new'
    assert_select 'h3.panel-title'
    assert_select 'div.panel-body'
  end
end
