BDD is great, in my opinion, especially for working on larger projects with longer goals.<p>For example we're using BDD on a multi-million-dollar multi-year project with dozens of stakeholders and programmers from multiple organizations.<p>When we bring a new person on board he can read the BDD and quickly understand what's happening.<p>We use Cucumber, Selenium, and also use TDD tools like RSpec and minitest/spec, and minitest/benchmark.
Chat rooms are sometimes a dangerous place to ask questions. Mobs form really quick.<p>There are plenty of companies doing TDD. I've been practicing it in my past few projects and have only good things to say. I probably write around 50% of tests first, the rest is written after implementation to expand coverage.
