RSpec 功能测试 Active Record 非唯一错误

Question

在此先感谢您的帮助！我刚刚开始学习使用 RSpec、FactoryGirl 和 Capybara 进行测试。我的功能测试因似乎是重复的用户名而失败。我已经安装了 db cleaner gem。另外，当我通过控制台检查 test db 时，没有用户记录。你能帮我理解我做错了什么吗？

以下是我的两个功能测试和错误。

1

require "rails_helper"
feature "Creating Articles" do
let(:user) {FactoryGirl.create(:user)}
let(:article) {FactoryGirl.create(:article)}

    def fill_in_signin_fields
        click_link("Sign in")
        fill_in "user[email]",        with: user.email
        fill_in "user[password]",     with: user.password
        click_button "Log in"
    end

    scenario "A user creates a new article" do
        visit '/'

        click_link("New Article")
        expect(page).to have_text "You need to sign in or sign up before continuing."

        fill_in_signin_fields
        click_link("New Article")

        fill_in "Title",    with: article.title
        fill_in "Body",     with: article.body
        click_button "Create Article"

        #expect(page).to have_content article.title
        #expect(page).to have_content article.body


    end
end

require 'rails_helper'

        fill_in "user[name]",                  with: user.name
        fill_in "user[email]",                 with: user.email
        fill_in "user[password]",              with: user.password
        fill_in "user[password_confirmation]", with: user.password
        click_button "Sign up"
    end

    scenario 'a user signs up' do
        visit root_path
        click_link "Sign up"
        fill_in_singup_fields
        expect(page).to have_content("Welcome! You have signed up successfully.")
    end 

end

You have signed up successfully." in "Blogger New Article Submit Link Sign up Sign in Sign up × Email has already been taken Username Email Password (6 characters minimum) Password confirmation Log in"

Answer 1

创建工厂时，它被插入到测试数据库中。您收到这些错误是因为您要创建的文章和用户已经创建。

测试创建功能时（在本例中，针对文章和用户），您不希望也创建工厂对象。

解决方案：删除带有硬编码字符串的工厂和 fill_in。

例如，

fill_in "user[name]", with: "TestUser"
