In order to test your data, you must use an EVSSL certificate just like the one used in production (PRD) to report the lessor’s income. It is important that you use a separate certificate for testing in the FKT environment. If you test in the TFE environment, you can use the same EVSSL certificate that you use in PRD for final reporting. You must therefore use two separate certificates for testing (FKT) and production (TFE and PRD), respectively.  If you already have a certificate for testing, you can use this. The certificate for testing is ordered in accordance with the same procedure as described in section 2.2.2 Order an Extended Validation Certificate (EVSSL).
