It is thus more portable 13 than binary-rewriting coverage tools, but also a little less capable. 14 For instance, it does not probe inside && and || expressions, and can 15 be mildly confused by single statements with multiple function literals. 16 17 For usage information, please see: 18 go help testflag 19 go tool cover -help 20 */ 21 package main 22
