2008年12月2日 · 2. Test Driven Development (TDD) Test-driven development (TDD) is the name of a methodology introduced by Kent Beck in his book "Test Driven Development by Example". It is a software development process, it is not only about writing tests before code. The whole book is trying to explain it by patterns, workflows, culture and so forth.

2012年1月24日 · Your first few TDD projects are going to probably result in worse design/redesign and take longer to complete as you are learning (at least in my experience). This is why you shouldn't jump into using TDD on a large critical project. My advice is to use "pure" TDD (acceptance/unit test everything test-first) on a few small projects (100-10,000 ...

2009年8月22日 · So here is what I learned: There are some testing frameworks written in bash and for bash, however.... It is not so much that Bash is not suitable for TDD (although some other languages come to mind that are a better fit), but the typical tasks that Bash is used for (Installation, System configuration), that are hard to write tests for, and in particularly hard to …

2013年9月24日 · AFAIK, TDD originally didn't distinguish between unit tests and integration tests. It remains that an integration test is generally much more costly in terms of resources you need to set up, which is why mocks were identified as a good practice even in early TDD literature. From Test-Driven Development By Example ("Mock object" pattern) :

2009年5月12日 · TDD is absolutly helpful in understanding the Domain model. TDD can be used to help define the Domain model causei it is a design technique as Carl Manaster stated above. TDD will help you recognize when and where to implement a design pattern, if / when an object is being defined in the wrong domain etc.

2010年6月29日 · TDD is development specific whereas agile refers more to the project style (although I get what you're asking). TDD can be a great development practice WHEN USED CORRECTLY. Use TDD from the beginning with waterfall and incorporate it at the end in agile. As an extra, look at BDD because there are many times when it will outweigh TDD –

It follows the SEAT TDD pattern: Setup - prepare the test conditions by manipulating the objects, tables, and/or data. Exercise - invoke the production code. Assert - check that the actual result equals the expected result. Teardown - return everything back to the way it …

The direct effect of production code becoming worse is that the class under test tend to become large and handles many things (violation of Single Responsibility Principle) and harder to maintain. This defeats the purpose of TDD, that is to get production code testable, extensible and more importantly: reusable.

2008年9月29日 · Using the Adapter pattern is most definitely the standard TDD approach to the problem. You could, however, also just create the other end of the TCP connection and have your test harness drive that. IMO the widespread use of adapter class obfuscates the most important parts of a design, and also tends to remove a lot of stuff from being tested ...

2009年4月11日 · I believe that a common misconception amongst developers is, they mistakenly make a strong association between testing frameworks and TDD principles. I would advise re-reading the official docs on TDD; bearing in mind that, there is no real relationship between testing frameworks and TDD. After all, TDD is a paradigm not a framework.
