chefspec：render_file未能检查在另一种情况下

Question

考虑以下配方去除模板的内容：

recipe_name = 'mongodb' 
    service_name = if node['szdigi'][recipe_name]['version'].to_f < 2.6 
        'mongodb' 
       else 
        'mongod' 
       end 

    conffile = "/etc/#{service_name}.conf" 

    # Add configuration 
    template conffile do 
    source 'mongodb/mongodb-conf.erb' 
    owner 'root' 
    group 'root' 
    mode 0o644 
    end 

    # Remove old config file 
    file '/etc/mongodb.conf' do 
    action :delete 
    only_if { node['szdigi'][recipe_name]['version'].to_f >= 2.6 } 
    end 

...及以下chefspec测试：

require_relative 'spec_helper' 

describe 'szdigi::mongo_test' do 
    before(:all) do 
    @conf_file = '/etc/mongodb.conf' 
    end 

    context 'Mongo 2.4' do 
    let(:chef_run) do 
     runner = ChefSpec::SoloRunner.new 
     runner.node.normal['szdigi']['mongodb']['version'] = '2.4.14' 
     runner.converge(described_recipe) 
    end 

    it 'creates mongo conf file' do 
     expect(chef_run).to create_template(@conf_file) 
     .with_mode(0o644) 
     .with_owner('root') 
     .with_group('root') 
    end 

    it 'does not remove /etc/mongodb.conf' do 
     expect(chef_run).not_to delete_file(@conf_file) 
    end 

    it 'defines authentication options' do 
     expect(chef_run).to render_file(@conf_file).with_content { |content| 
     expect(content).to match(/^\s*auth\s*=\s*true\s*$/) 
     } 
    end 
    end 

    context 'Mongo 2.6' do 
    before :all do 
     @conf_file = '/etc/mongod.conf' 
    end 

    let(:chef_run) do 
     runner = ChefSpec::SoloRunner.new 
     runner.node.normal['szdigi']['mongodb']['version'] = '2.6.12' 
     runner.converge(described_recipe) 
    end 

    it 'creates mongo conf file' do 
     expect(chef_run).to create_template(@conf_file) 
     .with_mode(0o644) 
     .with_owner('root') 
     .with_group('root') 
    end 

    it 'defines authentication options' do 
     expect(chef_run).to render_file(@conf_file).with_content { |content| 
     expect(content).to match(/^\s*auth\s*=\s*true\s*$/) 
     } 
    end 

    it 'removes 2.4 configuration file /etc/mongodb.conf' do 
     expect(chef_run).to delete_file('/etc/mongodb.conf') 
    end 
    end 
end 

配方不正是我想要什么：当版本属性设置为2.4.x和/etc/mongod.conf时，它会创建/etc/mongodb.conf，否则将使用auth = true。在后一种情况下，它也删除了现在已过时的/etc/mongodb.conf。

然而，只要配方包含file '/etc/mongodb.conf'资源，chefspec在蒙戈2.4范围内的it 'defines authentication options'失败：

Failure/Error: 
    expect(chef_run).to render_file(@conf_file).with_content { |content| 
    expect(content).to match(/^\s*auth\s*=\s*true\s*$/) 
    } 

    expected Chef run to render "/etc/mongodb.conf" matching: 

    (the result of a proc) 

    but got: 

任何想法，我应该怎么改写render_file测试2.6范围内才能取得成功？

我会用一个单一的顶级if node['szdigi'][recipe_name]['version'].to_f >= 2.6，然后重组方进入的两个分支。聪明的flow-y位的使用很好，但不。
