簡單的Rspec長度驗證測試 - NoMethodError：未定義的方法`之前'爲＃<RSpec :: Core :: ExampleGroup :: Nested_2：0x007fb8a24bac00>

Question

我有一個奇怪的問題，其中在我的模型規範之一，驗證長度對於某些領域，我的測試不會因爲這個錯誤而通過。我有另外三個模型，其中規範沒有任何失敗問題，驗證測試基本上完全相同。

排除故障有點改變（例如，spec_helper.rb包含config.include Capybara::DSL），但仍然有相同的問題。

這裏是我的測試中questions_spec.rb：

it "is not valid when title is too long" do 
    question = FactoryGirl.create(:question) 
    before {question.title = "a" * 101 } 
    it { should_not be_valid } 
end 
it "is not valid when brief is too long" do 
    question = FactoryGirl.build(:question) 
    before { question.brief = "a" * 501 } 
    question.should_not be_valid 
end 

我的錯誤：

Failures: 

1) Question is not valid when title is too long 
Failure/Error: before {question.title = "a" * 101 } 
NoMethodError: 
    undefined method `before' for #<RSpec::Core::ExampleGroup::Nested_2:0x007fb89df51c90> 
# ./spec/models/question_spec.rb:36:in `block (2 levels) in <top (required)>' 

2) Question is not valid when brief is too long 
Failure/Error: before { question.brief = "a" * 501 } 
NoMethodError: 
    undefined method `before' for #<RSpec::Core::ExampleGroup::Nested_2:0x007fb8a24bac00> 
# ./spec/models/question_spec.rb:41:in `block (2 levels) in <top (required)>' 

而且我spec_helper.rb：

ENV["RAILS_ENV"] ||= 'test' 
require File.expand_path("../../config/environment", __FILE__) 
require 'rspec/rails' 
require 'rspec/autorun' 
require 'capybara/rspec' 
require 'foreigner-matcher' 

# Requires supporting ruby files with custom matchers and macros, etc, 
# in spec/support/ and its subdirectories. 
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.check_pending! if defined?(ActiveRecord::Migration) 

RSpec.configure do |config| 

#add Capybara commands 
config.include Capybara::DSL 
config.include FactoryGirl::Syntax::Methods 

# Clean up the database 
require 'database_cleaner' 
config.before(:suite) do 
    DatabaseCleaner.strategy = :truncation 
    DatabaseCleaner.orm = "mongoid" 
end 

config.before(:each) do 
    DatabaseCleaner.clean 
end 

# ## Mock Framework 
# 
# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line: 
# 
# config.mock_with :mocha 
# config.mock_with :flexmock 
# config.mock_with :rr 

# 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 = false 

# If true, the base class of anonymous controllers will be inferred 
# automatically. This will be the default behavior in future versions of 
# rspec-rails. 
config.infer_base_class_for_anonymous_controllers = false 

# Run specs in random order to surface order dependencies. If you find an 
# order dependency and want to debug it, you can fix the order by providing 
# the seed, which is printed after each run. 
#  --seed 1234 
config.order = "random" 

end 

編輯：這是我的idea_spec.rb測試對與之配合相同的格式。

describe "when title is too long" do 
    idea = FactoryGirl.create(:idea) 
    before {idea.title = "a" * 101 } 
    it { should_not be_valid } 
    end 
    describe "when brief is too long" do 
    idea = FactoryGirl.create(:idea) 
    before { idea.brief = "a" * 501 } 
    it { should_not be_valid } 
    end

塊應該在之前運行之前後面所有的測試，所以它有去外面的它塊。如果代碼是特定於某個場景的，那麼只需刪除之前的代碼，因爲它沒有真正做任何事情。

it "is not valid when title is too long" do 
    question = FactoryGirl.create(:question) 
    question.title = "a" * 101 
    question.should_not be_valid 
end
