單元測試與Cobertura緩慢

我最近集成了Cobertura到我的Ant構建腳本中，我在想我是否正確執行它，因爲它顯着減慢了運行單元測試所花費的時間。單元測試與Cobertura緩慢

下面是一個簡單的控制檯輸出：

... 
[junit] Running gov.nyc.doitt.gis.webmap.strategy.markup.ViewportDeterminingMarkupStrategyTest 
[junit] Tests run: 5, Failures: 0, Errors: 0, Time elapsed: 0.38 sec

...

似乎腥，每個試運行後的Cobertura說：

[junit] Cobertura: Loaded information on 282 classes. 
[junit] Cobertura: Saved information on 282 classes. 
...

這裏是我的Ant構建腳本我的單元測試任務：

<target name="unit-test" depends="compile-unit-test"> 
    <delete dir="${reports.xml.dir}" /> 
    <delete dir="${reports.html.dir}" /> 
    <mkdir dir="${reports.xml.dir}" /> 
    <mkdir dir="${reports.html.dir}" /> 

    <junit fork="yes" dir="${basedir}" failureProperty="test.failed" printsummary="on"> 
     <!-- 
       Note the classpath order: instrumented classes are before the 
       original (uninstrumented) classes. This is important. 
      --> 
     <classpath location="${instrumented.dir}" /> 
     <classpath refid="test-classpath" /> 

     <formatter type="xml" /> 
     <test name="${testcase}" todir="${reports.xml.dir}" if="testcase" /> 
     <batchtest todir="${reports.xml.dir}" unless="testcase"> 
      <fileset dir="TestSource"> 
       <include name="**/*Test.java" /> 
       <exclude name="**/XmlTest.java" /> 
       <exclude name="**/ElectedOfficialTest.java" /> 
       <exclude name="**/ThematicManagerFixturesTest.java" /> 
      </fileset> 
     </batchtest> 
    </junit> 
</target>

我的設置和輸出是否正確？如果單獨運行單元測試需要2.234秒，並且在Cobertura的構建腳本中運行需要3分鐘，這是否正常？

我看不出有什麼問題（除了使用Ant :-P），但這種延遲是絕對不正常的。 –

我認爲你有另一個首選的工具，而不是螞蟻？你會推薦什麼？ –

maven和gradle都是對ant的巨大改進。向maven項目添加cobertura是微不足道的。 –
