func main() { flag.Parse() }
func m2() int { return t2() }

file test.go:

package main
import "flag"
var sT = "b"
func init() { flag.StringVar(&sT, "b", sT, "B") }
func t2() int { return 0 }

file main_test.go:

package main
import "testing"
func TestCoverage(i *testing.T) {
   if m2() != 0 { i.Fail() }
}

build:

$ cd app
$ go test -c -covermode=count -coverpkg ./...
$ ./app.test -b a:b -test.coverprofile z.cov #fails silently
$ ./app.test        -test.coverprofile z.cov #works

What did you expect to see?

z.cov in directory

What did you see instead?

z.cov missing
