Rspec的塊（3級），在<頂部（必填）>錯誤

Question

提交項目時我收到以下錯誤特拉維斯CI：

Failures: 

    1) salt on unsupported distributions we fail 
    Failure/Error: expect { subject }.to raise_error(/Unsupported platform: Unsupported/) 
     expected Exception with message matching /Unsupported platform: Unsupported/ but nothing was raised

這裏是salt_spec.rb：

require 'spec_helper' 

describe 'salt' do 

    context 'on unsupported distributions' do 
    let(:facts) {{ :osfamily => 'Unsupported' }} 

    it 'we fail' do

     ) 
     end 
    end 
    end 
    ['Archlinux', ].each do |distro| 
    context "on #{distro}" do

      'hasstatus' => 'true', 
      'hasrestart' => 'true'

      'hasrestart' => 'true'

     end 
    end 
    end 
end 

如果我正確理解了block (3 levels) in <top (required)>，那麼第5行和第11行之間的縮進是錯誤的，但它對我來說似乎是正確的。任何和所有這方面的幫助將不勝感激，因爲這是我第一次處理rspec，我正在嘗試學習。

編輯 我有這個固定的自己。我改變了這個從我的代碼：

context 'on unsupported distributions' do 
    let(:facts) {{ :osfamily => 'Unsupported' }} 

    it 'we fail' do 
     expect { subject }.to raise_error(/Unsupported platform: Unsupported/) 
    end 
    end 

要這樣：

context 'on unsupported distributions' do 
    let(:facts) {{ :osfamily => 'Unsupported' }} 

    it 'we fail' do 
     should compile.and_raise_error(/Unsupported platform: Unsupported/) 
    end 
    end 

，它似乎現在路過。我想我的問題是這樣的：這是正確的還是我錯誤地通過了測試？ （：事實） '上不支持的分佈' 做 設

上下文：

Answer 1

通過改變以下解決這個{{：osfamily => '不支持的'}}

it 'we fail' do 
    expect { subject }.to raise_error(/Unsupported platform: Unsupported/) 
end 

向該：

（：事實）{{：osfamily => '不支持的'}}

it 'we fail' do 
    should compile.and_raise_error(/Unsupported platform: Unsupported/) 
end 

'上不支持的分佈' 做 設上下文
