it gives me an error like - "Constructor not defined: [MassUpload].<Constructor>(ApexPages.StandardController)"
To solve this issue i wrote the constructor like-
PageReference pageRef = Page.Mass_Upload;//VF page name
pageRef.getParameters().put('id', String.valueOf(acc.Id)); //for page reference
Test.setCurrentPage(pageRef);
ApexPages.StandardController sc = new ApexPages.StandardController(acc);
MassUpload controller = new MassUpload(sc);
// test_MassUploadExhibitA controller=new test_MassUploadExhibitA(new ApexPages.StandardController(acc));
But still it gives me the same error.
