> The whole point of test-mode is that you can run your transaction as if it was running on the live-mode network. The solution is to test in test mode. Live mode just runs real cards, it should be have identically to test mode.

This is unreasonable. Test environment is never the same as prod. It's irresponsible to anyone you're actually accepting money from not to try the E2E flow in production.

Even if card processing is identical, who is say everything else in your flow is? It's either going to be you or a stranger on the internet being the first to try it for real.
