You can do it two ways 

One : insert the big object into the test class
Customer_Interaction__b bo = new Customer_Interaction__b();
bo.Account__c = “001R000000302D3”;
bo.Game_Platform__c = “PC”;
bo.Play_Date__c = “2015-01-01T23:01:01Z”;
bo.In_Game_Purchase__c = “A12569”;
bo.Level_Achieved__c = “41”;
bo.Lives_This_Game__c = “3”;
bo.Score_This_Game__c = “5500”;
bo.Play_Duration__c = “25”;

Two : Use Stub API of salesforce apex
