适用于单元测试的SpecFlow/BDD? [英] SpecFlow/BDD for Unit Tests?

问题描述

似乎互联网没有明确的答案，也没有一套原则可以帮助我回答问题.因此，我在SO上向伟大的人们求助，以帮助我找到答案或指导思想:)

Seems like the internet doesn't have a definitive answer, or set of principles to help me answer the question. So I turn to the great folk on SO to help me find answers or guiding thoughts :)

SpecFlow对于.NET中的BDD非常有用.但是，当我们谈论BDD时，我们只是在谈论集成/验收测试，还是在谈论单元测试-完全替代TDD?

SpecFlow is very useful for BDD in .NET. But when we talk about BDD are we just talking integration/acceptance tests, or are we also talking unit tests - a total replacement for TDD?

我只在小型项目中使用过它，但我发现即使对于单元测试，SpecFlow仍可以改善代码文档和语言方面的思考. Converseley，我看不到一个地方的完整测试代码，因为这些步骤是分散的.

I've only used it on small projects, but I find that even for my unit tests, SpecFlow improves code documentation and thinking in terms of language. Converseley, I can't see the full code for a test in one place - as the steps are fragmented.

现在是您.......

Now to you..........

我忘了提到我在RoR社区中看到了RSpec，该社区使用BDD样式的语法进行单元测试.

I forgot to mention that I see RSpec in the RoR community which uses BDD-style syntax for unit testing.

推荐答案

我最近开始使用 SpecFlow 进行BDD测试，但我仍然使用单元测试和集成测试.

I've recently started to use SpecFlow for my BDD testing, but also, I still use unit and integration tests.

基本上，我将测试分为单独的项目:

Basically, I split the tests into seperate projects:

• 规格
• 集成
• 单位

我的单元测试用于测试单个方法，不执行任何数据库调用或任何外部引用.我对单个方法调用(可能有时是两个)使用集成测试，这些方法确实与外部资源(例如数据库或Web服务等)进行交互.

My unit tests are for testing a single method and do not perform any database calls, or external references whatsoever. I use integration tests for single method calls (maybe sometime two) which do interact with an external resources, such as a database, or web service, etc.

我使用BDD描述模拟项目业务/领域要求的测试.例如，我将为一个项目的发票生成功能制定规范.或与购物篮一起使用.这些测试遵循

I use BDD to describe tests which mimick the business/domain requirements of the project. For example, I would have specs for the invoice generation feature of a project; or for working with a shopping basket. These tests follow the

语义类型.

我的建议是根据需要拆分测试.避免尝试使用SpecFlow执行单元测试.

My advise is to split your tests based on your needs. Avoid trying to perform unit testing using SpecFlow.
