在开玩笑测试中将公共数据放在哪里 [英] Where to put common data in jest tests

问题描述

我不知道如何组织代码进行玩笑测试.

I am not sure how to organize code for jest testing.

我在 __tests__ 下有我的所有测试，在 __mocks__ 下有我的所有模拟.现在我想在测试之间共享一些数据:它们不是现有函数的模拟，它们只是我想在不同文件中使用的一些 javascript 对象.

I have all my tests under __tests__ and all my mocks under __mocks__. Now I have some data I want to share between tests: they are not a mock of an existing function, they are just some javascript object I'd like to use in different files.

我应该创建一个 __data__ 目录吗?

Should I create a __data__ directory?

还是将它们放在 __mocks__ 下?

Or put them under __mocks__ anyway?

或者在__tests__目录下，不把-test放在文件名中?

Or in the __tests__ directory without putting -test in the file name?

推荐答案

简短的答案是您想要的任何地方.

The short answer is anywhere you want.

JavaScript 在其生命周期中经历了许多不同的阶段，并且有许多不同类型的人在使用它.这可能就是为什么如今大多数工具都是高度可配置的，以允许个性化(定制).

JavaScript has had a lot of different stages in its life and a lot of different types of people using it. Which is probably why most tools these days are highly configurable, to allow for personalization (customization.)

甚至 Jest 本身也显示出这些迹象.例如，测试匹配器将在 __tests__ 文件夹或包含 .spec 或 .test 的文件中查找测试.

Even Jest itself shows these signs. For instance the test matcher will look for tests in either __tests__ folders or with files that are contain .spec or .test.

或者按照他们的文档以可视化的方式:

Or as per their docs in a visual manner:

├── __tests__
│   └── component.spec.js # test
│   └── anything # test
├── package.json # not test
├── foo.test.js # test
├── bar.spec.jsx # test
└── component.js # not test

对于夹具和其他测试文件，答案是一样的，没有一种方法可以做到.

With regards to fixtures and other test files the answer is the same, there is no one way to do it.

选择适合您的.

我建议 __tests__ 结构将夹具数据放置在使用它的测试附近，如果多个测试需要访问，则将其进一步移到项目中，直到它位于公共位置.

I recommend for the __tests__ structure placing fixture data close to the test thats using it, and if multiple tests need access then move it further up the project until its in a common place.

我的偏好是一个 tests 文件夹，用于将测试、装置和测试与 src 代码分开.

My preference is a tests folder to keep the tests, fixtures, and testing separate to the src code.
