测试驱动的开发(TDD)和行为驱动开发(BDD)是两个流行的软件开发方法,优化测试和质量保证。188金宝搏官网登录app

TDD集中在编写代码之前编写测试

BDD集中在编写代码之前定义系统的行为。

你用哪一个?你用,还是第三个?

Test-Driven Development (TDD) and Behavior-Driven Development (BDD) are two popular approaches to software development that prioritize testing and quality assurance.<\/p>

\u00a0<\/p>

TDD focuses on writing tests before writing code<\/p>

BDD focuses on defining the behavior of the system before writing code.<\/p>

\u00a0<\/p>

Which one do you use? Do you use either, or a third one?<\/p>","quoteUsername":"IOan","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote & Reply","Share":"Share"}}}">

国际海事组织,选择TDD(测试驱动开发)和BDD(行为驱动开发)取决于各种因素,包括

  1. 您的项目的性质
  2. 团队动力,
  3. 个人喜好。让我来解释一下:
  • TDD是一种软件188金宝搏官网登录app开发实践,编写实际代码之前编写测试。这个过程通常涉及编写一个失败的测试,编写代码让测试通过,然后重构代码。TDD强调发展分解成更小的、易于管理的步骤,有助于确保代码满足指定的需求。TDD是适合于项目需求定义和重点是个别单位代码的正确性和行为(如函数、方法类)。它促进高水平的测试覆盖率,可以提高代码的质量,可维护性,以及促进重构。TDD也可以作为文档的代码应该如何使用。
  • BDD是TDD的延伸,关注系统的行为和交互从用户的视角。BDD强调合作开发人员、测试人员和业务利益相关者定义需求在一个更自然语言格式的形式(通常是“Given-When-Then”场景)。然后使用这些场景为基础编写测试和代码。BDD是有用的项目与复杂的业务逻辑或那些需要技术和非技术团队成员之间的密切合作。它有助于消除技术和业务涉众之间的差距通过提供一个共同的语言来描述系统行为。BDD鼓励一个更全面的方法来测试,确保软件从用户的角度表现如预期。188金宝搏官网登录app
  • 其他方法:还有其他的开发方法,如验收测试驱动开发(ATDD),其重点是捕获需求编写测试验收标准和基于这些标准。股票和BDD相似但通常包括一个狭义的范围。

最终的选择取决于您的项目的具体需求和上下文。考虑一些因素,比如项目复杂性、团队组成、利益相关者的参与和协作所需的水平。你可能还会发现,有助于结合元素TDD和BDD或调整它们以适合您的特定需求。

值得注意的是,无论您选择的方法,最重要的方面是要优先考虑编写测试,确保良好的测试覆盖率。测试有助于早期发现问题,在重构提供了信心,有助于您的软件的总体质量。188金宝搏官网登录app

IMO, the choice between TDD (Test-Driven Development) and BDD (Behavior-Driven Development) depends on various factors, including<\/p>
  1. the nature of your project<\/li>\t
  2. team dynamics, and<\/li>\t
  3. personal preference. Let me explain:<\/li><\/ol>
    • TDD <\/strong><\/u>is a software development practice where you write tests before writing the actual code. The process typically involves writing a failing test, writing the code to make the test pass, and then refactoring the code. TDD emphasizes breaking down development into small, manageable steps and helps ensure that the code meets the specified requirements.\u00a0\u00a0TDD is well-suited for projects where requirements are well-defined and the focus is on the behavior and correctness of individual units of code (e.g., functions, methods, classes). It promotes a high level of test coverage, which can enhance code quality, maintainability, and facilitate refactoring. TDD can also serve as documentation for how code should be used.<\/li>\t
    • BDD <\/strong><\/u>is an extension of TDD that focuses on the behavior and interactions of the system from a user's perspective. BDD emphasizes collaboration between developers, testers, and business stakeholders to define requirements in a more natural language format (usually in the form of \"Given-When-Then\" scenarios). These scenarios are then used as a basis for writing tests and code.\u00a0BDD is useful for projects with complex business logic or those that require close collaboration between technical and non-technical team members. It helps bridge the gap between technical and business stakeholders by providing a common language to describe system behavior. BDD encourages a more holistic approach to testing, ensuring that the software behaves as expected from a user's perspective.<\/li>\t
    • Other Approaches<\/strong><\/u>: There are other development approaches, such as Acceptance Test-Driven Development (ATDD), which focuses on capturing requirements as acceptance criteria and writing tests based on those criteria. It shares similarities with BDD but often involves a narrower scope.<\/li><\/ul>

      The choice ultimately depends on the specific needs and context of your project. Consider factors like project complexity, team composition, stakeholder involvement, and the level of collaboration required. You may also find it helpful to combine elements of TDD and BDD or adapt them to suit your specific requirements.<\/p>

      It's worth noting that regardless of the approach you choose, the most important aspect is to prioritize writing tests and ensuring good test coverage. Tests help catch issues early, provide confidence during refactoring, and contribute to the overall quality of your software.<\/p>","quoteUsername":"anuvip","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote & Reply","Share":"Share"}}}">

我与Seb玫瑰。他们都是相同的。

从他的博客“介绍TDD和BDD”https://cucumber.io/blog/bdd/intro-to-bdd-and-tdd/

BDD, TDD, ATDD,规范的例子,他们都是一样的。他们在外面工作,使用示例指定系统应该如何行为,这些例子是表示在无处不在的整个团队可以理解的语言,包括非技术成员,然后,一旦自动化,你得到验证,这意味着你可以告诉当你的文档是最新的,它意味着你知道当回归爬,这意味着你可以看到有多少系统已经实现的开发团队。

I am with Seb Rose here. They are all the same.<\/p>

From his blogpost \u201cIntroduction to TDD and BDD\u201d\u00a0https:\/\/cucumber.io\/blog\/bdd\/intro-to-bdd-and-tdd\/<\/a><\/p>

BDD, TDD, ATDD, Specification by Example \u2013 they\u2019re all the same. They work from the outside in, they use examples to specify how the system should behave, those examples are then expressed in a ubiquitous language that the whole team understands, including the non-technical members, and then, once you\u2019ve automated it, you get verification, which means that you can tell when your documentation is up to date, it means that you know when a regression has crept in, it means you can see how much of the system has been implemented by the development team.<\/p><\/blockquote>

两者都有。

TDD由软件开发部门生产生活,BDD整个项目团队(或3朋友:业务+开发人员+测试人员一起)为188金宝搏官网登录app了帮助理解需求和测试它们。

Both.<\/p>

\u00a0<\/p>

TDD by a development department producing the software to be put live, BDD for the whole project team (or the 3 amigos: business + developers + testers all together) in order to help understanding of the requirements and testing them .<\/p>","quoteUsername":"alex_read","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote & Reply","Share":"Share"}}}">
