IBM recent announced that is has created a Unit Testing tool for Mainframe computers. Remember those big, bulky, COBOL / FORTRAN machines running UNIX you read about in high school textbooks? Those beasts are STILL part of every monetary transaction even now. Recently the programs running on those machines now get to benefit from the unit testing process.
This is great. I was very intrigued by the article and the concept that unit testing has reached into the once thought of ‘not possible’ environment of mainframes. Maybe one day soon banks will be able to process cheques faster than 5 days.
