Some notes from my tdd session
Here's a quick notes from the TDD session which I conducted some time back. Introduction Writing test before writing production code. Design as you go along. Follow Red-Green-Refactor paradigm Benefits Spot design flow early. Test before the production code is built. Identify poort requirements or requirement gaps. Reduced testing time. The test forms the functional document for your code. Quickly identify bugs. Reduces the cost of bugs in the long run. Low level regression test suite. Road blocks to
