Simulate credit card payments with Systempay

[nadjk]

Good morning all.

My site is up and running, and online. It is already used regularly by people who pay by credit card.

I use the Systempay V2 1.13.1 payment module, and my site uses Prestashop version 1.7.6.1.

I would like to "simulate" payments by credit card which would allow me to access until the order is confirmed. So I would like to know the procedure to follow, and the steps to follow.

(I have read the Systempay documentation for Prestashop versions 1.5, 1.6 and 1.7, and I can't seem to find what I'm looking for. And I find that the documentation is not clear at all)

Thanks everyone.
