To be able to test data before reporting, you must have a special NemID test certificate.
In the FKT (test environment), you must use a test certificate for non-production environments. If you wish to test in the TFE environment, you can use the same certificate as used in production to make the final reporting. If you do not have a NemID certificate, it must be ordered from NETS here. Read more about test certificates in appendix 3 - Test certificates.
