如何使用工廠創建要使用Rspec和Capybara進行測驗的測驗資料-有解無憂

我正在嘗試使用 rspec/capybara 測驗我的分頁功能。我使用 FactoryBot 創建了這些文章，但遇到了兩個問題。如果我創建資料：

在一個before塊中，資料被保存到資料庫中，并且在套件運行后不會被擦除。
在場景塊內并用于save_and_open_page查看資料是否顯示在螢屏上，它不顯示。所以，我相信資料沒有足夠的時間來保存。

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

這是工廠：

FactoryBot.define do
  factory :article do
    sequence(:title) {|i| "Article #{i}"}
    body {"This is the test body of the article."}
  end
end

這是我的測驗套件。我只展示一個示例，因為其余部分的概念相同：

RSpec.feature "Paginations", type: :feature do

  before(:all) do
    ActionController::Base.allow_forgery_protection = true

    # FactoryBot.create_list(:article, 100)
  end

  before(:each) do
    visit articles_path
  end

  after(:all) do
    ActionController::Base.allow_forgery_protection = false
  end

  scenario "user visits articles home page to see only 10 articles", js: true do
    FactoryBot.create_list(:article, 10)

    save_and_open_page

    expect(page).to have_css "div.item-container-sizing.item-container-padding.flex-row-space-between", count: 10
  end
end

uj5u.com熱心網友回復：

您的主要問題是無序執行。您在創建測驗所需的物件之前訪問該頁面，因此這些物件在呈現的頁面上不可見（在呈現頁面時它們不存在）。對于大多數測驗，您不希望visit在 before 塊中呼叫，除非您有一系列測驗都需要相同的測驗資料并訪問相同的頁面。在這種情況下，只需將移動visit到場景中。此外，不要過度指定要查找的元素的選擇器，因為這會使您的測驗變得脆弱。您沒有顯示您的 html 的外觀，但假設此頁面僅顯示一個文章串列，則僅檢查您的一個類可能就足夠了，或者將您的期望范圍限定為頁面區域，

scenario "user visits articles home page to see only 10 articles", js: true do
    FactoryBot.create_list(:article, 10)
    visit articles_path

    # save_and_open_page

    expect(page).to have_css "div.item-container-sizing.item-container-padding.flex-row-space-between", count: 10
  end
