Subject RE: need help for test cases of api/commands

Meghna,

I see that there's MockProjectManagerImpl.  So basically, you're trying to mock the service
itself?  

You can use your own components.xml that has all the Mock classes.  Take a look at components.xml,
it has a reference to DefaultComponentLibrary which contains code to return different managers.
 You don't have to write your own componentlibrary because the components.xml can also specify
manager implementations.  You can add the following:

<manager name="name" class="class"/>

You can even pass paramters to the implementation.

<manager name="name" class="class">
  <param name="name">"value"</param>
</manager>

So in this case, you probably want something like

<manager name="ProjectManager" class="com.cloud.projects.MockProjectManagerImpl">
  <param name="abc">def</param>
</manager>

You can also write your own components.xml and set the following parameter in environment.properties
to reference your components.xml.

cloud-stack-components-specification=[path to your own components.xml]

Let me know if you have any questions.
