Question

我试图找出这段代码的错误。即它无法找到方法＆＃39; stub_model＆＃39;。试图寻找解决方案，但在任何地方我看起来我的文件似乎是好的。请看一下，也许我不能看到一个简单的错误。非常感谢：）书籍模型在db。

中创建

我的观点规范（spec / view / books_spec.rb）如下所示：

require 'rails_helper'

describe 'books/new' do

  it 'displays the book form' do
    book = stub_model(Book)
    assign(:book, book)
    render
    expect(rendered).to have_selector("form label[for *= 'Title']")
    expect(rendered).to have_selector("form label[for *= 'Author']")
    expect(rendered).to have_selector("form label[for *= 'Cover Photo']")
    expect(rendered).to have_button "Add Book"
  end
end

，错误如下：

1) books/new displays the book form
     Failure/Error: book = stub_model(Book)
     NoMethodError:
       undefined method `stub_model' for #<RSpec::ExampleGroups::BooksNew:0x00000103e61870>
     # ./spec/views/books_spec.rb:6:in `block (2 levels) in <top (required)>'

我的rails_helper.rb看起来像：

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require 'spec_helper'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'

# Requires supporting ruby files with custom matchers and macros, etc, in
# spec/support/ and its subdirectories. Files matching `spec/**/*_spec.rb` are
# run as spec files by default. This means that files in spec/support that end
# in _spec.rb will both be required and run as specs, causing the specs to be
# run twice. It is recommended that you do not name files matching this glob to
# end with _spec.rb. You can configure this pattern with with the --pattern
# option on the command line or in ~/.rspec, .rspec or `.rspec-local`.
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|
  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # RSpec Rails can automatically mix in different behaviours to your tests
  # based on their file location, for example enabling you to call `get` and
  # `post` in specs under `spec/controllers`.
  #
  # You can disable this behaviour by removing the line below, and instead
  # explicitly tag your specs with their type, e.g.:
  #
  #     RSpec.describe UsersController, :type => :controller do
  #       # ...
  #     end
  #
  # The different available types are documented in the features, such as in
  # https://relishapp.com/rspec/rspec-rails/docs
  config.infer_spec_type_from_file_location!
end

和我的Gemfile.rb：

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.2.rc1'

Answer 1

你的rspec-rails版本是什么？

根据Changelog，此Commit mock_model和stub_model自版本3.0.0的rspec-rails后删除。

rspec模拟在另一个gem rspec-activemodel-mocks中被外部化。你应该把它包含在Gemfile中并试一试。

希望有所帮助

Answer 2

这应该是对ahnbizcad的评论，但我缺乏正确执行此操作的声誉。

应通过添加进行修复

require 'rspec/active_model/mocks'

到spec_helper.rb

Rspec视图未定义方法stub_model
