definitely agree that in the good old mainframe days unit testing was a de rigueur phase of the development cycle.

In these days of rapid development, time to market and dare I say it outsourcing code development, it no longer seems to be drilled into developers (not trying to tar all with the same brush here). This may be due to unrealistic time pressures applied.

I have seen cases of 'the contract says deliver the code, well here it is, box ticked, wheres my money?'
