in reply to Re^2: 'state' variables and unit testing
in thread 'state' variables and unit testing

Something like this untestable too

To me it looks like a bug, not just untestable. Tests just reveal the bug.

Let me rephrase my earlier point: APIs are testable or not testable; state variables are just a way to implement an API. state vars are a tool, and neither good nor evil; it's only misuse of state vars (and thus broken APIs) that makes stuff hard to test.
