Hi Mahesh,

As per your, my under standing was Content document is shared with the Campaign) so please records in order in test class.

First - Create Campaign record
2nd  - Create ContentDocument
3rd - Create ContentDocumentLink 

Please create ablve records in stepwise and call this main class for test coverage. Foe more details refer below link (ContentDocument & ContentDocumentLink)
