1)如下定义流程文件:
<workflows>
    <workflow name="example" type="URL" location="/samples/comment-arg.xml"/>
</workflows>
这样就定义了一个名称为example,位置在/samples/comment-arg.xml的流程文件

2)建立测试类com.hongsoft.os.Test
里面的main方法的代码如下:
        counter = 0;  //要测试的变量
        Map inputs = new HashMap();
        inputs.put("test", this); //key: "test"  value: 本类的对象      
        long id = workflow.initialize("example", 1, inputs);//把map传入
        assertEquals("beanshell script not parsed correctly", 2, counter);//判断

3)流程定义的initial actions定义如下:
<initial-actions>
    <action id="1" name="Start Workflow">
      <pre-functions>       
        <function type="beanshell">
          <arg name="script">
                    com.hongsoft.os.Test test = transientVars.get("test");
                    test.counter++;           
                    test.counter++;
          </arg>
        </function>
      </pre-functions>
      <results>
        <unconditional-result old-status="Finished" status="Underway" step="1" owner="${caller}"/>
      </results>
    </action>
</initial-actions>
这样,在调用workflow.initialize()方法时,将调用beanshell里面的脚本

最后,test.counter由0变为了2.
