  SpecFlow was an open-source BDD (Behavior-Driven Development) testing framework
  for .NET that allowed teams to write executable specifications in natural language
  using the Gherkin syntax. Originally developed by TechTalk, it was acquired by
  Tricentis in 2020 and reached end-of-life on December 31, 2024. The community
  continuation is Reqnroll, a fork maintaining full backward compatibility.

      SpecFlow is a BDD framework for .NET that bridges the communication gap
      between domain experts and developers by enabling natural language
      specifications (Gherkin) to be executed as automated tests. It supports
      NUnit, xUnit, and MSTest as underlying test runners. Reached end-of-life
      December 31, 2024; succeeded by the community-driven Reqnroll project.
