Test your code until your brains ooze from your eye sockets

Yeah!:thumbsup: Real artists ship, not test.

I later found out I couldn't even open the friggin form after he had fixed it. It was such a small fix he didn't think it would've been necessary to test it... Worst part is that I didn't check his fix and put it live at the customer! Now who's the jackass? My non-testing, over-confident colleague or me, the one responsible :) Of course I'm not innocent myself, but I always at least test what I just fixed (that some other part of our software breaks because of the 'fix' is just details ;p ).
It's an OO world.

Actually we always blame people that don't work at the company anymore ;p

}Always a good technique - and often true, as those who've left are the ones who couldn't code well enough!

That depends on which direction your company is going. In the company I'm at, good coders are leaving because of the bad ones. The bad ones aren't budging.

Compile? Huh? Wuss!!! :P I just RDP into the server, write a few lines and save. Then I go for a smoke. If the phone rings, something went wrong.

I agree: testing your own code will never produce half as many bugs as testing another's. The reason is simple: you only test cases that you can think of. But if you can think of them, you've probably covered them in your code. It's only when some comes around with test cases that you didn't think of that the truly nasty bugs turn up.

For practical reasons you should therefore set a reasonable limit to your testing. Hint: 'no more bugs found' is not a reasonable limit.You will always find bugs, I agree with this. However, I never tested the code in question, at all. That is the reason for the Mantra. I catch so many bugs and problems just by testing my own code before you give it to the users to test. To not test your code, thoroughly on a basis of principal, indicates to me that you might not be a good coder. (not you in particular :))

"No, that is just the earthly manifestation of the Great God Retardon." - Nagy Vilmos (2011) "It is the celestial scrotum of good luck!" - Nagy Vilmos (2011)I always hate "pilot" projects. You get a subset of the data to develop around. Then they schedule the full dataset as though there won't be any changes necessary. Every. Time. There will be data that does not fit. Once we had a pilot project to convert addresses from one system to another. Management wanted consistency in department titles. After doing the pilot and coming up with a conversion table, the full run was as though we had done nothing. It would have been better to run the whole 1.2 million addresses than just the 50,000 they had given us. In the end, we found 150 different ways the data entry clerks had come up with to indicate "Human Resources". And that is just for one department. I just finished another conversion that I was given a pilot set of data for. Again, the full set had conditions not encountered in the subset. Hard to test around those situations.

Once management is entrenched in supporting stupidity, all bottom up/grass roots efforts at making things better are destined to fail. The only way you can fix a situation like that is to be a top level manager and incent the right behavior and fire those that don't follow. This is a lesson I've learned the hard way.

Just achieve 110% code coverage in your testing :). 100% coverage is that every branch is tested. 110% is when you test that every condition that can get you into every branch, is also tested. You'll find all those buggy error handling paths. You'll find all those buggy conditions. You'll even find a bunch of (error handling) code elsewhere in the project that's buggy. Still not perfect through, for starters, you'll miss all the design and requirements interpretation errors. If there's multiple paths to exercise the same code, you'll usually miss some of those too. Like you said, there's just no substitute for having someone else test your code.
We can program with only 1's, but if all you've got are zeros, you've got nothing.
