This is a great answer, but perhaps you could clarify some points for me: * I'm of a functional persuasion, I like to think about types before code, I already tend break things up into testable components (also known as pure functions). What benefits might I find by adopting TDD? * I understand the there are different benefits to be had from the act of writing tests and the artefact that is produced (ie the test suite). Do you the expect the tests that you write find bugs immediately? Or does the artefact only help to document code/detect regressions?
