SpecFlow/Cucumber Is Only The Name Of A Tool
SpecFlow, Cucumber and the others are just tools that facilitate the creation and running of executable behaviour specifications, to be used when a team is focused on using Behaviour-Driven Development to mature their software development practices.
Too many times I have heard team members and managers with a low maturity in and understanding of BDD talk about "the specflows" or "the cucumbers". Please, no, have some respect! Even though the developers and testers may use those tools, nobody in the team really should be focusing on or mentioning the names of those tools in their everyday conversations about software development. Instead of saying the tool's name, they should be talking simply about "Behaviour Specifications", "behaviours", "specifications", "specs" or "scenarios".
