Loader getting error!!..

Hi Team,

I have an Apex code which used below SOQL,

ID cUID=  UserInfo.getUserId() ;

        User cU= [Select id, Name, ContactId from User where id = :cUID limit 1];

        Contact cC= [Select id, Name, AccountId, Account.name from Contact where id = :cU.ContactId limit 1];

        ID accountId = cC.AccountId;

The ContactId will have a value only for users who are enabled for Partner or Customer Portal accounts.

How do I create a Test Class and test it?
Also, it has lightning components, how do I test it?

 

I'm doing the simple lightning components challenge and have hit this problem in my existing trailhead org and a brand new dev org that I've just created:
