I'll come from a heavily typed and statically typed and linked enviroenmemnt (Eiffel),

and since im doing erlang for 1 month now, I understand  what u said, and came to the same conclusion:

the less typed, the more dynymically typed the language is, the more u need test rather than relying on the compiler/linker .

ive experimenting XP (extreme programming ) approach recently, which put the focus on testing heavily, , and its not surprising that the originators of that (ward/beck) are smalltalker (which is dynamically typed).

in their case, its not an option !

but do u have a test suite internally, at ericsson, which was not open-sourced ? is it alinke these Xunit test suite ?
