请注意，Go 1.2 (Q4 2013, rc1 is available)现在将显示test coverage results：

go testgo tool covercover
$ go get golang.org/x/tools/cmd/cover

go test-cover
$ go test -coverprofile fmt
ok      fmt 0.060s  coverage: 91.4% of statements
$

go tool cover
Frank Shearar mentions：
The latest versions of Go (2013/09/19) use: 
go test -coverprofile <filename> <package name>
Details on how to generate and analyze coverage statistics can be found by running the commands 
$ go help testflag
$ go tool cover -help
Ivan Black提及in the comments： 
go test -coverprofile cover.outgo tool cover -html=cover.out -o cover.htmlcover.html
我甚至不想等待浏览器打开，所以我定义了这个别名： 
alias gc=grep -v -e " 1$" coverage.out
我只输入
gc
，并列出了尚未涵盖的所有行(此处：
coverage.out
行不以“
1
”结尾)。
