</div></div>Pragmatically speaking, code should be tested such that if either:<br>
- some precondition it has is changed (either elsewhere in the same<br>
code base or in the behaviour of some other code base) that we find<br>
out<br>
- if someone changes the code itself and breaks an existing use case,<br>
we find out.<br>
<br>
Exactly what that means may be different for different routines :).<br>
<br>
My general rule is to start with testing each entry and exit path and<br>
any domain or range corner cases.<br>
