如何幹這rspec測試？

Question

我正在使用寶石，並且想要爲其添加40個其他rspec測試。寶石配備了一套規格，但它們不是非常乾燥 - 我想要添加的40多個測試中的每一個都需要10-12行代碼（每一個非常相似）。

該測試的一個示例如下，但我創建了一個要保存更多代碼的要點。在這裏粘貼更多似乎不切實際。

這裏的要點是：https://gist.github.com/2400225

我想要做的是有這些測試的40-45在一個單一的源文件，該文件枯燥有道理。

shared_examples_for "Firefox browser" do 
    it "should return 'Firefox' as its browser" do 
    @useragent.browser.should == "Firefox" 
    end 

    it "should return :strong as its security" do 
    @useragent.security.should == :strong 
    end 

    it { @useragent.should_not be_webkit } 
end 

# (repeating code would start here. I want 40-50 of these blocks.) 
describe 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8) Gecko/20100101 Firefox/4.0b8' do 
    before do 
    @useragent = UserAgent.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8) Gecko/20100101 Firefox/4.0b8') 
    end 

    it_should_behave_like "Firefox browser" 

    it "should return '4.0b8' as its version" do 
    @useragent.version.should == "4.0b8" 
    end 

    it "should return '20100101' as its gecko version" do 
    @useragent.gecko.version.should == "20100101" 
    end 

    it "should return 'Macintosh' as its platform" do 
    @useragent.platform.should == "Macintosh" 
    end 

    it "should return 'Intel Mac OS X 10.6' as its os" do 
    @useragent.os.should == "Intel Mac OS X 10.6" 
    end 

    it "should return nil as its localization" do 
    @useragent.localization.should be_nil 
    end 

    it { @useragent.should_not be_mobile } 
end

這只是紅寶石！

你可以在這裏做任何事你可以做的紅寶石。嘗試這樣的事情：

BROWSERS = [ 
    [ 
     'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8) Gecko/20100101 Firefox/4.0b8', 
     'Firefox browser', 
     '4.0b8', 
     '20100101', 
     'Macintosh', 
     'Intel Mac OS X 10.6', 
     nil, 
     false 
    ], 
    # more entries 
] 

BROWSERS.each do |desc| 
    agent_string,behave_as,version,gecko_version,platform,os,localization,mobile = *desc 
    describe agent_string do 
     before do 
     @useragent = UserAgent.parse(agent_string) 
     end 

     it_should_behave_like behave_as 

     it "should return '#{version}' as its version" do 
     @useragent.version.should == version 
     end 

     it "should return '#{gecko_version}' as its gecko version" do 
     @useragent.gecko.version.should == gecko_version 
     end 
     # etc! 
     end 
end
