Does cucumber do away with the need to write unit tests?

Question

I am a little confused by the sheer number of testing frameworks available for Ruby/ROR.

I have recently watched the Cucumber Railscasts and found them very interesting.

Answer 1

Personally I don't think that you should stop writing unit tests. As an acceptance testing tool, Cucumber should replace your functional tests and, if you writing, view tests.

Cucumber features are supposed to be simple and coupled to the real user's value a given feature has.
