问题描述

我都对TDD与BDD感到困惑:)在以下各点中,TDD和BDD有何不同?

I am all confused with TDD vs BDD :)How does TDD and BDD differ in each of below point?

  1. 开发:首先是测试用例,其次是开发
  2. RestService(HTTP):不进行休息电话吗?如果是这样,

  1. Development: Test case first, development follows next
  2. RestService(HTTP): Don't make rest calls? If so,

a)我们是否仅使用模拟对象返回硬编码的json?

a) do we return only hardcoded json using a mock object?

b)如何处理REST调用失败?我们也应该有测试用例吗?

b) how to handle REST call failures? We should have test case for that too?

特别是对于第2项,我在Google上搜索了很多文章,但是找不到关于如何处理休息电话的示例(代码)方法.

Especially for item 2, i have googled so many articles, but couldn't find a sample (code) approach on how to handle rest calls.

推荐答案

BDD实际上是来自TDD的,因此有点混乱也就不足为奇了! BDD与TDD完全相同(如果您要针对整个系统使用BDD,则为ATDD),但是没有单词"Test".事实证明,它可能非常强大.

BDD is actually derived from TDD, so it's not surprising there's a little confusion! BDD is exactly like TDD (or ATDD if you're doing it for a whole system), but without the word "Test". It turns out that can be pretty powerful.

特别是,它使开发人员可以与非技术业务人员就系统应该做什么进行对话.您也可以使用它与一个类或代码模块进行对话,即使是与技术专家对话也是如此.

Particularly, it lets developers have conversations with non-technical business people about what the system should do. You can also use it to have conversations about what a class should do, or a module of code should do, even with a technical expert.

因此,在您的REST服务示例中,您可以想象我是一名开发人员,并且是一位了解REST服务应该做什么的专家.

So in the example of your REST service, you can imagine that I'm a dev and you're an expert who knows what the REST service should do.

...

我:好的,我已经完成阅读,让我们进行更新.能给我一个典型更新的例子吗?
:您来了.
我:太棒了,您希望它以成功或失败来回应.在任何情况下应该会失败吗?
:好的.该记录显示了它的最后更新时间.如果与此同时其他人已经对其进行了更新,则您提交时应该会失败.

Me: Okay, so I've done Read, let's do Update. Can you give me an example of a typical update?
You: Here you go.
Me: Fantastic, and you want it to respond just with success or fail. Is there any scenario in which it should fail?
You: Sure. The record shows when it was last updated. If someone else has already updated it in the meantime, yours should fail when you submit it.

因此,您看到可以使用BDD探索各种场景,包括REST服务周围的场景.诀窍是问:你能给我一个例子吗?"然后,您将得到一个具体的示例,如果需要,可以将其自动化.对话有助于我们寻找可能遗漏的 other 个示例和方案.

So you see you can use BDD to explore all kinds of scenarios, including those around a REST service. The trick is to ask, "Can you give me an example?" Then you get a concrete example, which you can then automate if you want to. The conversations help us look for other examples and scenarios which we might have missed.

请勿使用BDD工具自动为技术用户服务!诸如Cucumber,JBehave等的BDD工具使用的是真正的英语,它比代码难重构.如果您只是在做类似REST服务的操作,请使用JUnit,NUnit等.您可以在注释中添加给出,何时,然后",或制作一些DSL.

Don't use BDD tools to automate for a technical audience! BDD tools like Cucumber, JBehave etc. work with real English that's a lot harder to refactor than code. Use JUnit, NUnit etc. if you're just doing something like a REST service. You can put "Given, When, Then" in comments, or make a little DSL.

因此,现在您可以看到由于REST调用失败而导致的故障,如果我正在对其进行编码,我将有一个类似的示例:

So now you can see that with your REST call failure, if I were coding it, I'd have an example like:

等等.

您可以始终看到,我并没有真正使用测试"一词.测试是BDD中不错的副产品.它更多地用于需求的探索和规范. BDD中的对话是其中最重要的部分.

You can see that throughout, I'm not really using the word "test". Tests are a nice by-product in BDD. It's used more for exploration and specification of requirements. The conversations in BDD are the most important part of it.

找到将BDD用于REST的示例很棘手的原因首先是因为REST刻意简单,并且通常没有很多行为,其次是因为BDD的场景在实现上通常没有用措辞来表达,重点在于而不是服务或系统提供的价值(读取记录").

The reason it's tricky to find examples of using BDD for REST is first because REST is deliberately simple and doesn't often have a lot of behaviour, and second because BDD's scenarios aren't generally phrased in terms of their implementation, focusing instead on the value of what the service or system provides ("read a record").

如果做得好,TDD和ATDD完全相同.就示例和场景进行对话比对测试进行对话要容易得多.

TDD and ATDD are exactly the same, if they're done well. It's just easier to have conversations about examples and scenarios than it is to have them about tests.
