My bag of tricks – loose notes, design patterns, rules-of-thumb
&gt; Not Rocket Science Rule<p>I&#x27;ve been trying to introduce this into my current company for as long as I&#x27;ve been working there, with no success so far, with varying reasons:<p>- Unit tests for existing projects often fail
- Unit tests for existing projects take several minutes to run
- Our current build process cannot be automated.<p>Quite frustrating, especially since I&#x27;ve seen a lot of cases where it could&#x27;ve saved us from near-disasters.<p>EDIT:
I think on the subject of Emergence, the writer has missed one key point: emergence requires interplay between different levels of the system.
