I created the following files:
/tmp/mymodule/go.mod:
module module3
go 1.23.4
/tmp/mymodule/overlay.json:
{
"Replace": {
"/tmp/mymodule/test/context_builder.go": "/tmp/context_builder.go"
}
}/tmp/mymodule/submodule1/one.go:
package submodule1/tmp/mymodule/submodule1/one_test.go:
package submodule1
import (
"strings"
"testing"
_ "module3/test"
)
func TestSomething(t *testing.T) {
_ = strings.Repeat("abc", 2)
}/tmp/mymodule/test/context_builder.go:
package test
import (
"testing"
)
type StringGenerator func(n int) string
type Builder struct {
T *testing.T
}/tmp/context_builder.go:
package test
import (
"testing"
)
func init() {
panic("Here")
}
type StringGenerator func(n int) string
type Builder struct {
T *testing.T
}From /tmp/mymodule I then ran go test -run TestSomething ./submodule1 -coverpkg=./... -overlay=$PWD/overlay.json
What did you see happen?
ok module3/submodule1 0.005s coverage: [no statements]
What did you expect to see?
panic: Here
goroutine 1 [running]:
module3/test.init.0()
/tmp/mymodule/test/context_builder.go:8 +0x25
FAIL module3/submodule1 0.008s
FAIL
If I instead run go test -run TestSomething ./submodule1 -overlay=$PWD/overlay.json (without the coverpkg flag), I see this panic.
