You probably don’t need a specification framework

I think plain language specification frameworks like SpecFlow and Cucumber are great, but have a lot of overhead and are way overused.

If you don’t have non-technical folk collaborating with you on your specifications, try writing plain automated tests instead. This means using plain NUnit/MSTest over SpecFlow in C# or minitest over Cucumber in Ruby. You’ll avoid the overhead of maintaining a plain language specification framework and be able to focus on developing a great set of tests instead.

It’s easier than you think to add a plain language specification layer to a set of well structured plain tests. So only add the specification layer when you need it, because chances are you ain’t gonna.
