Hi Nishad,

This will be actually very simple. Code will be something like this - 
  
Test.startTest();

myClass.futuremethod( someID );

Test.stopTest();

Do refer to this link for further details - https://developer.salesforce.com/forums/?id=906F000000094QOIAY

Let me know if it helps.

Thanks,
Ray
