单元测试和功能测试之间的区别是什么?单元测试也可以测试函数吗?
当前回答
我们可以很简单地说:
黑盒:用户界面测试,比如功能测试 白盒:类似单元测试的代码测试

单元测试: 单元测试特别用于逐个组件地测试产品,特别是在产品开发过程中。 Junit和Nunit类型的工具还将帮助您按照单元测试产品。 **与其在整合之后解决问题,不如在开发早期就解决问题。
功能测试: 就测试而言,主要有两种类型的测试 1.功能测试 2.非功能性测试。
Non-Functional Test is a test where a Tester will test that The product will perform all those quality attributes that customer doesn't mention but those quality attributes should be there. Like:-Performance,Usability,Security,Load,Stress etc. but in the Functional Test:- The customer is already present with his requirements and those are properly documented,The testers task is to Cross check that whether the Application Functionality is performing according to the Proposed System or not. For that purpose Tester should test for the Implemented functionality with the proposed System.
单元测试告诉开发人员代码的工作是正确的;功能测试告诉开发人员代码正在做正确的事情。

单元测试和功能测试在现实生活中的类比可以描述如下:
Many times the development of a system is likened to the building of a house. While this analogy isn't quite correct, we can extend it for the purposes of understanding the difference between unit and functional tests. Unit testing is analogous to a building inspector visiting a house's construction site. He is focused on the various internal systems of the house, the foundation, framing, electrical, plumbing, and so on. He ensures (tests) that the parts of the house will work correctly and safely, that is, meet the building code. Functional tests in this scenario are analogous to the homeowner visiting this same construction site. He assumes that the internal systems will behave appropriately, that the building inspector is performing his task. The homeowner is focused on what it will be like to live in this house. He is concerned with how the house looks, are the various rooms a comfortable size, does the house fit the family's needs, are the windows in a good spot to catch the morning sun. The homeowner is performing functional tests on the house. He has the user's perspective. The building inspector is performing unit tests on the house. He has the builder's perspective.
总结一下,
单元测试是从程序员的角度编写的。它们用于确保类的特定方法(或单元)执行一组特定的任务。
功能测试是从用户的角度编写的。它们确保系统按照用户的期望运行。
在Rails中,单元文件夹用于保存模型的测试,功能文件夹用于保存控制器的测试,集成文件夹用于保存涉及任意数量的控制器交互的测试。fixture是一种组织测试数据的方法;它们驻留在fixture文件夹中。test_helper。Rb文件保存测试的默认配置。 你可以参观一下。
单元测试——测试单个单元,例如类中的方法(函数),模拟所有依赖项。
功能测试——又名集成测试,测试系统中的一部分功能。这将测试许多方法,并可能与数据库或Web服务等依赖项交互。
测试类型
Unit testing - In Procedural programming unit is a procedure, in Object oriented programming unit is a class. Unit is isolated and reflects a developer perspective Functional testing - more than Unit. User perspective, which describes a feature, use case, story... Integration testing - check if all separately developed components work together. It can be other application, service, library, database, network etc. Narrow integration test - double[About] is used. The main purpose is to check if component is configured in a right way Broad integration test (End to End test, System test) - live version. The main purpose is to check if all components are configured in a right way UI testing - checks if user input triggers a correct action and the UI is changed when some actions are happened ... Non functional testing - other cases Performance testing - calculate a speed and other metrics Usability testing - UX ...
