使用設計創建模型用戶后如何在 Rails 中進行集成測試

Question

我正在做一個在安裝設計之前工作的集成測試。 現在為重復鍵拋出錯誤。 試圖插入用戶。 問題是我正在做和測試的測試是針對一個甚至沒有關聯的類別模型。 我留下代碼和錯誤。 謝謝

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

錯誤如下：

感謝kevinluo201我通過在 users.yml 中配置兩個不同的電子郵件用戶解決了我的問題，盡管也在 test_helper.rb 中注釋了“fixtures：all”行。 您還可以運行測試。

用戶.yml：

one:
 email: email1@example.com

two: 
 email: email2@example.com
