SpecFlow is "red-green" feature development!
Step 1: Write a feature
Step 2: Watch it fail
Step 3: Implement step definitions
Step 4: Create domain skeleton
Step 5: Watch it fail
Step 6: Implement domain functionality
Step 7: Iterate steps 5 + 6 until scenario passes
Step 8: Iterate steps 2 - 7 until feature passes
