Overview

Cover is a program for analyzing the coverage profiles generated by 'go test -coverprofile=cover.out'.

Cover is also used by 'go test -cover' to rewrite the source code with annotations to track which parts of each function are executed. It operates on one Go source file at a time, computing approximate basic block information by studying the source. It is thus more portable than binary-rewriting coverage tools, but also a little less capable. For instance, it does not probe inside && and || expressions, and can be mildly confused by single statements with multiple function literals.

When computing coverage of a package that uses cgo, the cover tool must be applied to the output of cgo preprocessing, not the input, because cover deletes comments that are significant to cgo.

go help testflag
go tool cover -help
