如何添加模板文件中的RSpec木偶

Question

我有以下表現sudo的用戶，加載模板文件

class sudo { 
    if $::operatingsystemmajrelease < 7 { 
    $variable = $::operatingsystemmajrelease ? { 
     '6' => $::fqdn, 

    } 
    file { '/etc/sudoers' : 
     ensure => present, 
     owner => 'root', 
     group => 'root', 
     mode => '0440', 
     content => template('sudo/sudoers.erb'), 
    } 
    } 
} 

下面是我的RSpec的文件

vim test_spec.rb 
require 'spec_helper' 
describe 'sudo' do 
    it { should contain_class('sudo')} 
    let(:facts) {{:operatingsystemmajrelease => 6}} 

    if (6 < 7) 
    context "testing sudo template with rspec" do 
    let(:params) {{:content => template('sudo/sudoers.erb')}} 
    it {should contain_file('/etc/sudoers').with(
     'ensure' => 'present', 
     'owner' => 'root', 
     'group' => 'root', 
     'mode' => '0440', 
     'content' => template('sudo/sudoers.erb'))} 
    end 
    end 
end 

得到以下錯誤，當運行「耙規範「

.F 
Failures: 
    1) sudo testing sudo template with rspec 
    Failure/Error: 'content' => template('sudo/sudoers.erb'))} 
    NoMethodError: 
     undefined method `template' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0x7f5802e70bd8>

Failed examples: 
rspec ./spec/classes/test_spec.rb:12 # sudo testing sudo template with rspec 
rake aborted! 
ruby -S rspec spec/classes/test_spec.rb failed 

任何人都可以指導我如何用rspec-puppet測試模板。我衝浪網也打破了我的頭兩天以上都沒有幫助。

Answer 1

template是木偶解析器的功能，因此是不可你的單元測試。

如果你真的想要使用你現有的模板作爲夾具，你將不得不manually評估其ERB代碼。

更好的單元測試方法是在測試代碼中對測試數據進行硬編碼。

if (6 < 7) 
    context "testing sudo template with rspec" do 
    let(:params) {{:content => 'SPEC-CONTENT'}} 
    it {should contain_file('/etc/sudoers').with(
    'ensure' => 'present', 
    'owner' => 'root', 
    'group' => 'root', 
    'mode' => '0440', 
    'content' => 'SPEC-CONTENT'} 
    end 
end 

使用實際有效的模板在驗收或集成測試領域更有趣。

您可以選擇要麼放棄對內容的字符串或正則表達式：這裏它

context 'with compress => true' do 
    let(:params) { {:compress => true} } 

    it do 
     should contain_file('/etc/logrotate.d/nginx') \ 
     .with_content(/^\s*compress$/) 
    end 
    end 

    context 'with compress => false' do 
    let(:params) { {:compress => false} } 

    it do 
     should contain_file('/etc/logrotate.d/nginx') \ 
     .with_content(/^\s*nocompress$/) 
    end 
    end
