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.

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.

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 ...

2010年4月4日 · TDD is defined by Wikipedia as follows:. Test-driven development (TDD) is a software development technique that relies on the repetition of a very short development cycle: first the developer writes a failing automated test case that defines a desired improvement or new function, then produces code to pass that test and finally refactors the new code to acceptable …

2013年8月3日 · This one of the most difficult requirements to acchieve, and depending of the "school" there may be a need for temporary unit tests during TDD too. When a test is only testing the contracts, this is acchieved, but that may be not enough for high code coverage requirements. Consistent result: Effectively a result of "enough" independency ...

2014年3月21日 · You can't retrofit TDD to existing code. You can write unit tests against existing code, but that is not TDD. TDD is a design process where you write the tests first. I would suggest writing unit tests for the key public interfaces of your existing code, and to consider using TDD when adding new classes or methods. –

2010年7月14日 · TDD also helps you get awesome test coverage and kinda forces you to build well structured, separated code => Good testability. If you build a system 100% TDD you will have tests on everything meaning your system will be alot safer to changes and the possibility of implementing bugs in the future will be way smaller.

2011年3月25日 · I'm attempting to learn TDD but having a hard time getting my head around what / how to test with a little app I need to write. The (simplified somewhat) spec for the app is as follows: It needs to take from the user the location of a csv file, the location of a word document mailmerge template and an output location.

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 …

2010年7月1日 · With TDD you should almost always be near 100% coverage when developing new code since you don't develop any code that you don't need to pass tests. Only when you think the code is so simple that you don't need a test (say, like an automatic property in C#), should you have code that isn't specifically covered.
