also be responsible for writing and executing the unit tests for that code. If so, have all the unit
tests checked by someone else, preferably a tester. Make sure they know as soon as you??™ve found
each bug you can reproduce. Monitor their relations with testers to ensure that they are neither

fication) nor too distant (such that antagonism occurs). They may also have to handle third-line
