我首先要说的是，我可能用错了方法，我愿意接受其他测试方法。
我有一个Rails/React应用程序，我正试图添加更多的测试。我之前写过的rspec测试完全包含在后端检查的内容。现在我试着写一个测试，检查创建一个博客文章。当我测试的表单是一个Rails视图时，我曾经这样做过，但是当表单是在React中构建在前端时，我从来没有这样做过。
这是我的gem文件:source 'https://rubygems.org'

这是我的测试:
require 'rails_helper'
feature 'user signs in', %Q{
As an admin user
I want to create new posts
when I am signed in
} do
scenario 'admin creates new blog post', js: true do
user = FactoryBot.create(:user_1)
post = FactoryBot.create(:post_1)
visit '/post/new'
# binding.pry
fill_in 'title', with: post.title
fill_in 'body', with: post.body
fill_in 'image', with: post.image
fill_in 'keywords', with: post.keywords
binding.pry
click_button 'Submit'
binding.pry
expect(page).to have_content(post.title)
end
end
我一直在使用binding.pry和save_and_open_page来试图弄清楚发生了什么。到达/post/new并正确填写表格。这部分是有效的。但是当它点击Submit时，出现以下错误:
[1] pry(#<RSpec::ExampleGroups::UserSignsInAsAnAdminUserIWantToCreateNewPostsWhenIAmSignedIn>)> 2021-08-20 13:51:45 -0400 Rack app ("GET /" - (127.0.0.1)): #<ActionController::UnknownFormat: HomepagesController#index is missing a template for this request format and variant.
request.formats: ["application/json"]
request.variant: []>
我不太确定这里发生了什么。我猜我错过了配置的某些部分，以获得这个测试的JS方面的工作?还需要注意的是，此表单在开发/生产中是有效的。表单中的数据应该被发送到Posts Controller。
使此工作的另一个选项。为后端编写响应测试会更有意义吗?然后只用Jest或其他库来测试前端功能?
表单正在提交，但是您在Home控制器中没有正确的格式。在index方法中，你应该添加你希望控制器如何处理js格式。
你能确保你的方法同时处理html和json这样:
respond_to do |format|
format.html # index.html.erb
format.json { render json: @whatever_you_want_to_return }
end
至于测试，您的测试是好的，但是您应该始终测试应用程序的所有部分，以确保它们返回您想要的结果。
