傳遞Java系統屬性以螞蟻測試

Question

我有螞蟻執行一個罐子用下面的代碼

<target name="start.my.jar" description="start my jar"> 
    <echo message="Starting the jar" /> 
    <java jar="${jars.dir}/${my.stub.jar}" fork="true" dir="${jars.dir}" spawn="true"> 
      <sysproperty key="properties.filename" value="${basedir}/path/path/path/filename.properties"/> 
     <arg value="start" /> 
    </java> 
</target> 

罐內部有一個與下面的代碼的類

public static MyFacade createFacade() throws FileNotFoundException, IOException { 
    return createFacade(System.getProperty(properties.filename)); 
}  

，然後有螞蟻測試目標是這樣配置的

<target name="test" depends="compile, support" description="perform unit tests"> 
    <mkdir dir="${build.test}" /> 
    <mkdir dir="${test-classes.dir}" /> 
    <javac srcdir="${build.test}" destdir="${test-classes.dir}" debug="${debug}" nowarn="${nowarn}" includeantruntime="false" deprecation="${deprecation}"> 
     <classpath refid="main.classpath" /> 
    </javac> 
    <junit printsummary="yes" haltonfailure="yes" showoutput="true" dir="${test-classes.dir}" fork="true" forkmode="perBatch" failureproperty="junit.failure" errorproperty="junit.error" haltonerror="no"> 
     <jvmarg value="-Xmx1G" /> 
     <jvmarg value="-Dcom.sun.management.jmxremote" /> 

     <classpath> 
      <pathelement location="${test-classes.dir}" /> 
      <pathelement location="${classes.dir}" /> 
      <!-- 
      For module restful_api 
      --> 
      <pathelement location="${build.deploy}" /> 
      <pathelement location="${classes.dir}" /> 
      <fileset dir="${build.lib}"> 
       <include name="*.jar" /> 
      </fileset> 
     </classpath> 
     <formatter type="plain" /> 
     <batchtest fork="yes" todir="${build.test}"> 
      <fileset dir="${build.test}"> 
       <include name="**/*AllTests.java" /> 
       <include name="**/*TestCase.java" /> 
      </fileset> 
     </batchtest> 
    </junit> 
    <fail message="Unittest failures - please check" if="junit.failure" /> 
    <fail message="Unittest errors - please check" if="junit.error" /> 
</target> 

我在這個測試目標模塊中的測試無法獲得屬性對於我在start.my.jar目標中指定的文件。有什麼我做錯了嗎？

Answer 1

搞怪夠了這個工作：

<jvmarg value="- Dproperties.filename=${basedir}/path/path/path/filename.properties"/> 

我用了一個前：

<sysproperty key="" value=""/> 

從來沒有做過

Answer 2

那是因爲你添加的屬性只是java的目標，這是一個獨立的運行時環境。 junit目標指定一個新的環境（因爲您爲它設置了一些JVM開關，您還需要指定系統屬性）。

試試這個：

<junit ...> 
    <sysproperty key="properties.filename" 
      value="${basedir}/path/path/path/filename.properties"/> 
    .... 
</junit> 

另一種方法是運行與-Dproperties.filename=...鍵每次ant任務（你可以設置在外部運行配置在Eclipse）。然而，缺點是每次你想運行任務時都要記住這一點（例如，在CI構建中或重新簽出）。
