帶Guard和Spork的Rspec不會運行某些測試，也不會給出失敗的詳細錯誤語句

Question

當我在我的規範中添加了測試時，我對每一個通過寫入的測試都懷疑，所以我添加了一些語法錯誤到代碼中。事實證明，Rspec沒有運行我最近的測試，所以語法錯誤沒有得到迴應。在下面的代碼中的註釋顯示在該Rspec的停止顯示用於測試綠色期或紅色F中的任意行：

require 'spec_helper' 

describe Api::PagesController do 
    def valid_session 
    {}

    before :each do 
     @page = create(:page) 
    end 
    it "assigns all pages as @pages" do 
     get :index 
     assigns(:pages).should eq([@page]) 
    end 
    it "returns json" do 
     get :index, format: :json 
     expect(response.body).to have_content @page.to_json 
    end 
    end 

    describe "GET show" do 
    before :each do 
     @page = create(:page)

    it "assigns the requested page as @page" do

     it "assigns a newly created page as @page" do 
     post :create, {page: attributes_for(:page)}, valid_session 
     assigns(:page).should be_a(Page) 
     assigns(:page).should be_persisted 
     end

當我有意添加的語法錯誤，前面的測試中，我看到紅色Fs的，而不是綠色的點，但沒有錯誤報道。早些時候，當有一個錯誤，我會看到（例如）：

16:10:14 - INFO - Running: spec/models/page_spec.rb 
Running tests with args ["--drb", "-f", "progress", "-r", "/Users/user/.rvm/gems/ruby-1.9.3-p194/gems/guard-rspec-1.2.1/lib/guard/rspec/formatters/notification_rspec.rb", "-f", "Guard::RSpec::Formatter::NotificationRSpec", "--out", "/dev/null", "--failure-exit-code", "2", "spec/models/page_spec.rb"]... 
.......F 

Failures: 

    1) Page Publishing returns unpublished pages 
    Failure/Error: expect(Page.unpublished).to eq [page_unpublished] 
    NameError: 
     undefined local variable or method `page_unpublished' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_4:0x0000010355b8c0>

Finished in 0.54212 seconds 
8 examples, 1 failure 

Failed examples: 

rspec ./spec/models/page_spec.rb:57 # Page Publishing returns unpublished pages 

Done. 

現在，當一個測試失敗，我只看到：

17:55:26 - INFO - Running: spec/controllers/pages_controller_spec.rb 
Running tests with args ["--drb", "-f", "progress", "-r", "/Users/user/.rvm/gems/ruby-1.9.3-p194/gems/guard-rspec-1.2.1/lib/guard/rspec/formatters/notification_rspec.rb", "-f", "Guard::RSpec::Formatter::NotificationRSpec", "--out", "/dev/null", "--failure-exit-code", "2", "spec/controllers/pages_controller_spec.rb"]... 
.....FF..Done. 

這種變化發生在一個漂亮的任意時間在編碼時，我沒有修改Guardfile或任何Spork配置細節。任何想法爲什麼發生這種情況？

Answer 1

它看起來像rspec的其中一個參數是--out/dev/null。所以你的輸出是從STDOUT重定向的。

一種可能性是這是由一個或多個不良測試引起的。你有沒有試過評論各種測試，看看你是否可以隔離有問題的測試？如果你按順序運行你的測試，我會在rspec過早退出的前後開始。
