It is feasible to base the decision to hire a testing lead on only the feedback from a development lead? Testing is something different from coding and it has different methodologies. Like every technology, a tester learns new things everyday and it will never end.
Since a development lead is different than a testing lead, it will not be possible for the dev lead to know all the methodologies and processes involved in testing. So what is the probability that the recruitment is feasible if done by development lead only and not by higher management?
