What did you do?

Create a module with the same name as a std library package, e.g. sync.

$ go mod init sync
go: creating new go.mod: module sync

$ echo "package somepackage

import \"testing\"

func TestFunc(*testing.T) {
    panic("error")
}" > some_test.go

$ go test ./...

What did you expect to see?

Some error, whether that be a warning that the module has a conflicting name or the test failing.

What did you see instead?

The tests pass, because the test command is actually running sync from the standard library.

$ go test
PASS
ok      sync    1.929s
