Test-driven development by example Kent Beck

Jun 24, 2012 - Dan recently blogged on the opportunity costs of our various practices, and used TDD as an example of a practice that carries such a cost. Feb 11, 2013 - Test driven development is a development process that is exactly what it sounds like, we develop our applications driven by a number of different tests. May 1, 2013 - The right test is the smallest leap we can find. Jul 29, 2013 - Visual Studio 2012 supports the concept of TDD through its unit testing framework. This involves writing all your tests up front before any development has taken place. It can take longer to produce software with TDD than without. 3 days ago - I use TDD as a method for learning the fundamentals of modular design, but I have to admit that I've mostly relied on the emerging discipline of the student for its effectiveness. Apr 28, 2014 - The idea behind TDD can be stated by improvising this phrase: 'lead by an example' to 'code by an example'. In this column, I'll walk through a simple example of using Visual Studio 2012, and its unit testing framework, to perform TDD. The process can be explained in five simple steps: 1. It goes beyond merely programming because it presents the programmer with example after example of code subject to constraints like “I can easily test this” or “I can extract this from its context to run it in isolation” or “I can add new behavior by adding code rather than changing it”. Apr 7, 2014 - Test-driven development is often taught using simple examples, such as calculating the scores for a game of ten-pin bowling. I recently recorded how I used TDD to solve a sample problem. Using the same practice effectively on a real code base isn't as easy. I find this the hardest part of Test Driven Development, for example, in the Roman Numerals problem I now always start with conversion of 0, 1, 5, and 10. 1 day ago - Please notice that the examples discussed in this post (encapsulation, OCP, TDD, frameworks) mostly increase the robustness of software systems.
