ruby-on-rails - 测试 View 编辑表单时 Rspec 失败

Question

我正在这里开发我的第一个 Rails 应用程序，但生成的两个测试没有通过:

Failures:

  1) gardens/edit renders the edit garden form
     Failure/Error: assert_select "inputgarden_name[name=?]", "garden[name]"

     Minitest::Assertion:
       Expected at least 1 element matching "inputgarden_name[name="garden[name]"]", found 0..
       Expected 0 to be >= 1.
     # ./spec/views/gardens/edit.html.haml_spec.rb:20:in `block (3 levels) in <top (required)>'
     # ./spec/views/gardens/edit.html.haml_spec.rb:18:in `block (2 levels) in <top (required)>'

  2) gardens/new renders new garden form
     Failure/Error: assert_select "inputgarden_name[name=?]", "garden[name]"

     Minitest::Assertion:
       Expected at least 1 element matching "inputgarden_name[name="garden[name]"]", found 0..
       Expected 0 to be >= 1.
     # ./spec/views/gardens/new.html.haml_spec.rb:19:in `block (3 levels) in <top (required)>'
     # ./spec/views/gardens/new.html.haml_spec.rb:17:in `block (2 levels) in <top (required)>'

Finished in 1.15 seconds (files took 2.74 seconds to load)
34 examples, 2 failures, 17 pending

Failed examples:

rspec ./spec/views/gardens/edit.html.haml_spec.rb:15 # gardens/edit renders the edit garden form
rspec ./spec/views/gardens/new.html.haml_spec.rb:14 # gardens/new renders new garden form

我不确定这是为什么。当我查看测试时，我有点惊讶路径不包含要编辑的 ID(类似于 /gardens/#{@garden.id}/edit)。当我尝试相应地编辑测试时，rspec 无法运行，告诉我 @garden 尚未实例化。

spec/views/gardens/edit.html.haml_spec.rb:

  1 require 'rails_helper'
  2
  3
  4 RSpec.describe "gardens/edit", type: :view do
  5   before(:each) do
  6     @garden = assign(:garden, Garden.create!(
  7       :name => "MyString",
  8       :square_feet => 1,
  9       :zone => 1,
 10       :garden_type => "MyString",
 11       :user => nil
 12     ))
 13   end
 14
 15   it "renders the edit garden form" do
 16     render
 17
 18      assert_select "form[action=?][method=?]", garden_path(@garden), "post" do
 19 
 20        assert_select "input#garden_name[name=?]", "garden[name]"
 21 
 22        assert_select "input#garden_square_feet[name=?]", "garden[square_feet]"
 23 
 24        assert_select "input#garden_zone[name=?]", "garden[zone]"
 25 
 26        assert_select "input#garden_garden_type[name=?]", "garden[garden_type]"
 27 
 28        assert_select "input#garden_user_id[name=?]", "garden[user_id]"
 29      end
 30   end
 31 end

我需要做什么才能通过这些测试？

编辑:这里是编辑 View

/app/views/gardens/edit.html.haml:

%h1 Editing garden

= render 'form'

= link_to 'Show', @garden
\|
= link_to 'Back', gardens_path

/app/views/gardens/_form.html.haml:

= simple_form_for(@garden) do |f|
  = f.error_notification

  .form-inputs
    = f.input :name
    = f.input :square_feet
    = f.input :zone
    = f.input :garden_type
    = f.association :user

  .form-actions
    = f.button :submit

Answer 1

您包含的错误消息表明未找到给定匹配器的 html 元素。

对于关联，简单表单 gem 默认生成 select 元素而不是 input 元素。 https://github.com/plataformatec/simple_form#associations

您需要将最后一个断言更改为:assert_select "select#garden_user_id[name=?]", "garden[user_id]"

我猜问题出在新 View 的规范中？
