如何在Rails中进行集成测试，然后通过设计创建模型用户

Question

我正在执行一项集成测试，该测试在安装devise之前已经起作用。现在，对重复的键抛出错误。尝试插入用户。事实是，我正在做的测试是针对没有关联的Category模型进行的。我留下了代码和错误。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：

对kevinluo201的致谢我通过在users.yml中配置两个不同的电子邮件用户来解决了我的问题尽管也在test_helper.rb中注释了“ fixtures：all”这一行。您也可以运行测试。

The users.yml：

one:
 email: [email protected]

two: 
 email: [email protected]
