Professionalism in medicine

● Surgeon 1 does the same operation over and over and makes a lot of money

● Surgeon 2 knows all the standard operations and has developed an innovative procedure, but makes less money than Surgeon 1

● Surgeon 3 practices own procedure regularly, but also travels abroad to teach other doctors how to practice the innovation

DDT checklist

✔Test code in the same repo

✔All tests are part of (continuous) builds

✔Tests should be FAST

✔Track coverage, don't let it fall

✔Pair with the developers

✔Help us with the corner cases

BDDBug Driven Development

(You get what you measure)

Overspecialization“Plain specialists”– Too narrow-minded– Ineffective– Poor at communication and collaboration

“Generalizing specialists” – Understand all required activities – Are best in one or few areas– Have a better chance of keeping their jobs

(and happy users)

At Codeborne

● We don't have strict roles● No testers, no analysts, no managers● Just craftsmen, who create software● We pair● And do everything what it takes● To create software from 0 to 100%

In more conservative organizations

● Let developers write the tests● (learn also to do that)● Do not waste time on regression testing● Do other stuff that matters● Trust, remember the common goal● Never accept the idea of that's the way its

done here

Let's do it!
