Does the test tool support Private to Commercial?
The short answer is that no, the test tool itself does not support that.
However, a more detailed answer depends on what is meant by Private to Commercial. If this is about employee login, parallel to NemID Medarbejdersignatur, that will not be supported by MitID until December 2021 at the earliest.
If it is about MitID for business owners, that will be available from the go-live date in May. However, it is a value add by Signicat, and not covered by the MitID test tool. We will of course make it possible to test said feature, but it has to be configured by Signicat.
