Documentation says that `go test -c` should "-c  Compile the test binary to
pkg.test but do not run it."

What exactly is the final name is not quite clear.

This is important for automation.

Initially I thought that "pkg" means "package name", but it seems
that go simply takes the last element of the import path.

Whatever decided is reasonable - but it should be documented.

    $  grep package $GOPATH/src/github.com/elazarl/goproxy/ext/html/html.go
    package goproxy_html
    $ # yes, bad name, I need to change it
    $ go test -c github.com/elazarl/goproxy/ext/html
    $ ls *.test
    html.test
