I was lucky enough to see\u00a0Uncle Bob<\/a>\u00a0give a presentation on\u00a0TDD<\/a>\u00a0this week.\u00a0 During his demonstration of the\u00a0Bowling Game<\/a>, I noticed he refrained from writing tests for the all the little helper methods he extracted during the course of the test-code-refactor cycle.\u00a0 In the past, I had a tendency to take these private methods, make them public and write tests against them.\u00a0 Something never felt right doing it, but it never hurts to have more tests, right?<\/p>\n

However, after watching Uncle Bob, I understand why you don\u2019t need to do that: the original method that spawned all the little helper methods is already well-tested.\u00a0 If there was a defect in the private helper method, the public method will inform you.\u00a0 Intuitively, I knew that and was beginning to go there.\u00a0 Uncle Bob just moved that process along faster, so thanks!\"adding-machine-buttons\"<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
