Scala from the Trenches
Kfir Bloch gave a presentation on test-driven development (TDD) and clean code. He defined some common TDD and clean code terms like unit testing, fakes, collaborators, stubs, matchers, integration tests, refactoring, and mocks. Bloch also demonstrated a use case of implementing a throttling mechanism for a prize server to prevent players from repeatedly requesting prizes. He showed how to refactor the code using TDD principles. Finally, Bloch invited the audience to connect with him on LinkedIn and GitHub or email him about open roles at Wix.
