Spring Integration: Unit test Start/Stop endpoint adapters

I have one jdbc inbound adapter and one jms adapter as follows:

<int-jdbc:inbound-channel-adapter id="fooInboundJdbcAdapter" query="SELECT * FROM foo WHERE status IS NULL" channel="fooJdbcChannel"
data-source="dataSource">
   <int:poller fixed-rate="10000"/>
</int-jdbc:inbound-channel-adapter>

<int-jms:message-driven-channel-adapter id="fooJmsMessageDrivenAdapter" 
connection-factory="jmsConnectionFactory"  
channel="fooJmsListenerChannel" 
destination="fooJmsQueue"/>

I used control-bus to start/stop these adapters. One of the method looks like:

public boolean startAdapter() {
  return controlChannel.send(new GenericMessage<String>("@" + fooInboundJdbcAdapter.getComponentName() + ".start()"));
}

Now, I am trying to write unit test for above method. I am confused about how I should unit test this method. Any help on this? controlChannel and fooInboundJdbcAdapter are injected in this case.
