在xml中自动生成JUnit结果的最佳方式是什么？

Question

我目前正在JUnit中编写一系列测试。我需要自动将结果导出为XML。我在读这样做的最好方法是通过扩展RunListener类并以这种方式编写XML。下面是我迄今为止所做的一些示例，但我正在努力解决已经运行的每个测试的信息。 '描述'类似乎没有任何有用的获取方法，我觉得我可能会这样做是错误的。

有人可以帮助如何从描述中获得有用的信息（例如，测试通过/失败，测试持续时间，测试名称等）还是给我一些建议，我应该怎么做？

public class XmlListener extends RunListener { 

    private final PrintStream fWriter; 

    public XmlListener(JUnitSystem system) { 
     this(system.out()); 
    } 

    public XmlListener(PrintStream writer) { 
     this.fWriter = writer; 
    } 

    @Override 
    public void testRunStarted(Description description) { 
     fWriter.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"); 
    } 

    @Override 
    public void testRunFinished(Result result) { 
     fWriter.append("\t\t</suite>\n"); 
     fWriter.append("\t</suites>\n"); 
     fWriter.append("</result>\n"); 
     printHeader(result.getRunTime()); 
     printFailures(result); 
     printFooter(result); 

    } 

    @Override 
    public void testStarted(Description description) { 
     fWriter.append("\t\t\t<case>\n"); 
     fWriter.append("\t\t\t\t<timestamp>" + "</timestamp>\n"); 
     fWriter.append("\t\t\t\t<className>" + "</className>\n"); 
     fWriter.append("\t\t\t\t<testName>" + "</testName>\n"); 
    } 

    @Override 
    public void testFinished(Description description) { 
     fWriter.append("\t\t\t\t<duration>" + "</duration>\n"); 
     fWriter.append("\t\t\t</case>\n"); 
     Iterator it = description.getAnnotations().iterator(); 
     while (it.hasNext()) { 
      fWriter.append(it.next().toString()); 
     } 
    } 

    @Override 
    public void testFailure(Failure failure) { 
     fWriter.append('E'); 
    } 

    @Override 
    public void testIgnored(Description description) { 
     fWriter.append('I'); 
    } 

    /** 
    * private methods 
    * @return 
    */ 

    private PrintStream getWriter() { 
     return fWriter; 
    } 

    protected void printHeader(long runTime) { 
     getWriter().println(); 
     getWriter().println("Time: " + elapsedTimeAsString(runTime)); 
    } 

    protected void printFailures(Result result) { 
     List<Failure> failures= result.getFailures(); 
     if (failures.size() == 0) 
      return; 
     if (failures.size() == 1) 
      getWriter().println("There was " + failures.size() + " failure:"); 
     else 
      getWriter().println("There were " + failures.size() + " failures:"); 
     int i= 1; 
     for (Failure each : failures) 
      printFailure(each, "" + i++); 
    } 

    protected void printFailure(Failure each, String prefix) { 
     getWriter().println(prefix + ") " + each.getTestHeader()); 
     getWriter().print(each.getTrace()); 
    } 

    protected void printFooter(Result result) { 
     if (result.wasSuccessful()) { 
      getWriter().println(); 
      getWriter().println("\t</suites>\n"); 
      getWriter().println("</result>\n"); 
      getWriter().println(" (" + result.getRunCount() + " test" + (result.getRunCount() == 1 ? "" : "s") + ")"); 

     } else { 
      getWriter().println(); 
      getWriter().println("FAILURES!!!"); 
      getWriter().println("Tests run: " + result.getRunCount() + ", Failures: " + result.getFailureCount()); 
     } 
     getWriter().println(); 
    } 

    /** 
    * Returns the formatted string of the elapsed time. Duplicated from 
    * BaseTestRunner. Fix it. 
    */ 
    protected String elapsedTimeAsString(long runTime) { 
     return NumberFormat.getInstance().format((double) runTime/1000); 
    } 
} 

更新 - Ant构建文件

<?xml version="1.0" encoding="UTF-8"?> 
<project name="COTPlus" default="main" basedir="."> 
<property name="src.dir" location="src" /> 

<target name="test" > 
<junit printsummary="on" haltonfailure="false"> 
    <formatter type="xml" /> 
    <batchtest todir="/test-reports"> 
    <fileset dir="${src.dir}" includes="**/ExampleTest.java" /> 
    </batchtest> 
</junit> 
</target> 

<target name="main" depends="test"> 
     <description>Main target</description> 
     <echo>${src.dir}</echo> 
    </target> 

</project>

您可以使用Ant脚本进行获取XML结果

<target name="test" > 

<javac srcdir="/src" 
    destdir="/bin" 
    classpath="/lib/junit.jar" /> 


<junit haltonfailure="false"> 
    <formatter type="xml" /> 
    <batchtest todir="/test-reports"> 
    <fileset dir="/bin" includes="tests/ExampleTest.class" /> 
    </batchtest> 
</junit> 
</target> 

这将生成一个XML到/测试报告文件夹。有关Ant构建的更多详细信息http://ant.apache.org/manual/tasksoverview.html
