...A bench test of an ATM probably doesn't involve real money. No one in finance is stupid enough to use real money on production environments for testing purposes.

There is test... And there is PROD. Never do the two meet. Ever.

If someone out there does, please make yourself known so we can get the investigators over there ASAP.

You can test in production if you have multi-tenancy aware services, where tenancy is some string value like Foo to make sure reads to Foo can only read data that was written to Foo.

That's not testing in production, that's just the same as saying your test VMWare environment is in the same datacentre as your prod VMWare environment.

Huh? You're telling me that you think they never test ATMs in prod? That's ridiculous.

You think they're just guessing that the test environment perfectly matches the prod environment?
