Certificate Authorities
-----------------------

The above example uses a self-signed certificate. This is convenient for testing but not
representative of real-world HTTPS deployment. To get closer to that we can use `HeldCertificate`
to generate a trusted root certificate, an intermediate certificate, and a server certificate.

	if err := DB.Migrator().AutoMigrate(&HNPost{}); err != nil {
		t.Fatalf("failed to auto migrate, got error: %v", err)

	if err := DB.Create(&hnPost).Error; err != nil {
		t.Errorf("Failed to create got error %v", err)
	}
