> It's not like programmers are immune from making such errors. You can put the wrong equation into a page of C or Java as you can onto an Excel spreadsheet.

The difference is that programmers know they will make such errors and thus have developed tools, techniques and a culture that acknowledges the necessity for testing to find and eliminate bugs.

In contrast, I'd wager that less than 0.01% of financial Excel sheets has automated tests, and less than 0.1% has a written test plan. If you confront your typical "work-hard-party-hard" hotshot trader with demands for such, the response is most likely "Testing? I wrote it, I know it works, do you think I'm stupid?"

LOL, seriously? How much software do you use every day that doesn't have bugs? Especially software that only gets used every now and then?


Yes, and that's despite all those efforts to reduce bugs. Imagine all the bugs found by tests going into production...

Or were you jsut put off by the phrase "eliminate bugs"? That wasn't meant to imply eliminating all bugs, just those the tests have found. And we all know they don't catch 'em all.


OK, put that way it makes sense and I agree with you.
