Rails：帶有Guard（+ spork和+ rspec）的黃瓜不能在更改時運行功能

Question

我最近嘗試安裝Cucumber來補充我的測試環境。我已經有了Guard和Spork和Rspec完美合作。我已經設置了一切，現在運行，包括黃瓜，但有兩件事情有點時髦。

第一期：當Guard運行Cucumber測試時，它在打印「禁用配置文件...」後暫停約10秒鐘。大約10秒後，它完全運行測試。 第二期：當我對我的功能（存儲在/features/users/sign_in.feature等子目錄中）或步驟定義進行更改時，guard不會運行測試。爲了讓我運行測試，我必須手動命中並且Guard繼續再次運行所有測試。顯然，這打破了守衛的目的。

下面是我的一些代碼：

重要Guardfile代碼

guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, 
       :rspec_env => { 'RAILS_ENV' => 'test' } do 
    watch('config/application.rb') 
    watch('config/environment.rb') 
    watch('config/environments/test.rb') 
    watch(%r{^config/initializers/.+\.rb$}) 
    watch('Gemfile') 
    watch('Gemfile.lock') 
    watch('spec/spec_helper.rb') { :rspec } 
    watch('test/test_helper.rb') { :test_unit } 
    watch(%r{features/support/}) { :cucumber } 
end 


guard 'cucumber' do 
    watch(%r{^features/.+\.feature$}) 
    watch(%r{^features/support/.+$})   { 'features' } 
    watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' } 
end 

功能/支持/ env.rb

require 'rubygems' 
require 'spork' 

Spork.prefork do 
end 

Spork.each_run do 
end 

require 'cucumber/rails' 

ActionController::Base.allow_rescue = false 
begin 
    DatabaseCleaner.strategy = :transaction 
rescue NameError 
    raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it." 
end 

Cucumber::Rails::Database.javascript_strategy = :truncation 

Answer 1

您忘了將env.rb代碼拆分爲prefork和each_run塊。嘗試：

require 'rubygems' 
require 'spork' 

Spork.prefork do 
    require 'cucumber/rails' 
end 

Spork.each_run do 
    ActionController::Base.allow_rescue = false 

    begin 
    DatabaseCleaner.strategy = :transaction 
    rescue NameError 
    raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it." 
    end 

    Cucumber::Rails::Database.javascript_strategy = :truncation 
end
