@zemyblue BuildInfo is not populated when go test. So this test can't be passed

I know. But without this test, the coverage ci is not satisfied.
I think we need to ignore the coverage error in this case.

Okay! But If we really want to test this version sync, we can try like this

func TestCheckLlibwasmVersion(t *testing.T) {
	f, err := os.Open(filepath.Join(moduleBasePath(t), "go.mod"))
	assert.NoError(t, err)
	res, err := io.ReadAll(f)
	assert.NoError(t, err)
	parsed := strings.Split(string(res), "\n")
	var expected string
	for _, line := range parsed {
		if strings.Contains(line, "github.com/line/wasmvm") {
			expected = strings.Split(strings.TrimSpace(line), " ")[1]
		}
	}
	got, err := wasmvm.LibwasmvmVersion()
	assert.NoError(t, err)
	assert.Contains(t, expected, got)
}

func moduleBasePath(t *testing.T) string {
	t.Helper()

	err := os.Setenv("GO111MODULE", "on")
	if err != nil {
		t.Fatalf("unable to set GO111MODULE env var: %v", err)
	}

	cmd := exec.Command("go", "list", "-f", "{{.Module.Dir}}")
	out, err := cmd.Output()
	if err != nil {
		t.Fatalf("failed to evaluate Go module base path: %v", err)
	}

	return strings.TrimSpace(string(out))
}
