flag '-tests' is not work

[timmyyuan]

I create a go test file (my_test.go) in a empty directory:

package my_test

import (
        "go.uber.org/goleak"
        "testing"
)

func TestFunc(t *testing.T) {
        defer goleak.VerifyNone(t)
        var x int
        x = 1 / x
}

And then add its mod file:

module my_test

go 1.15

require go.uber.org/goleak v1.1.10

Then, I use go-callvis to visit the call graph of my_test.go by

 go-callvis -tests .

There should be a function "TestFunc" displayed on the browser but I could not find it. Is this caused by my wrong operations?

I can't reproduce it on MacOS.

Sorry it's my mistake, the node of "TestFunc" should in testing package because it is called by tRunner actually.
