Banks remain on COBOL because of the quantity of code that's been tested in real life situation for decades. Yes IBM license for mainframe are expensive but it never fails. I worked on a migration project where only the tests would take a few thousand days. Yes they could be automated, but the regulations in place required that a human sign that all the test were executed at least once by a human. | ||

What do you mean "only the tests would take a few thousand days"? Did running the test suite take 10 years? Like literally what exactly do you mean? | ||
