[TDD] Unit tests and parameter validation

Tim Ottinger All Messages By This Member #35406 Where does that data come from? Programmers or external sources? Development time or runtime? I don't test against programmers but might test if data comes from a file or database. Humans can figure out when they're wrong, especially if they write tests. Of course I worry a bit more if the parameters are not type-safe and/or the ordering of parameters is not obvious and natural. So that leaves the last question as whether the interface invited advise.

The context for this in a class/methods that are used within an internal application - this is not an API that will be publicly exposed to external consumers. Thanks. -- blog: twitter: @eikonne
