【问题描述】：

我正在做一个集成测试，该测试在安装设计之前有效。现在为重复键抛出错误。试图插入用户。问题是我正在做和测试测试是针对一个甚至没有关联的类别模型。我留下代码和错误。谢谢

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: "measure tension", description: "This is the Category for measure tension"} }
     follow_redirect!
  end
  assert_template 'categories/index'
  assert_match "measure tension", response.body
 end

end

错误如下：

【问题讨论】：

检查 test_helper.rb 是否创建用户？或者如果您正在使用夹具，则检查夹具/用户是否有用户使用相同的电子邮件
非常感谢您的帮助。事实上，我有固定装置：所有，但在我的 users.yml 中我没有很好地配置用户。我将所做的更改留在答案中。

【解决方案1】：

感谢kevinluo201 我通过在 users.yml 中配置两个不同的电子邮件用户解决了我的问题尽管在 test_helper.rb 中也注释了“fixtures: all”行。您也可以运行测试。

users.yml:

one:
 email: email1@example.com

two: 
 email: email2@example.com
