如何在Jest中使用ESLint [英] How to use ESLint with Jest

问题描述

我正在尝试将ESLint linter与Jest测试框架一起使用。

I'm attempting to use the ESLint linter with the Jest testing framework.

Jest测试使用一些全局变量运行，如 jest ，我需要告诉linter;但棘手的是目录结构，Jest测试嵌入了 __ tests __ 文件夹中的源代码，因此目录结构如下所示：

Jest tests run with some globals like jest, which I'll need to tell the linter about; but the tricky thing is the directory structure, with Jest the tests are embedded with the source code in __tests__ folders, so the directory structure looks something like:

src
    foo
        foo.js
        __tests__
            fooTest.js
    bar
        bar.js
        __tests__
            barTest.js

通常，我' d在单个目录下进行所有测试，我可以在那里添加一个 .eslintrc 文件来添加全局...但我当然不想添加 .eslintrc 文件到每一个 __ test __ dir。

Normally, I'd have all my tests under a single dir, and I could just add an .eslintrc file there to add the globals... but I certainly don't want to add a .eslintrc file to every single __test__ dir.

目前，我刚刚将测试全局变量添加到全局 .eslintrc 文件中，但由于这意味着我现在可以在非测试代码中引用 jest ，这似乎不是正确的解决方案。

For now, I've just added the test globals to the global .eslintrc file, but since that means I could now reference jest in non-testing code, that doesn't seem like the "right" solution.

有没有办法让eslint根据某些基于目录名称的模式应用规则，或类似的东西？

Is there a way to get eslint to apply rules based on some pattern based on the directory name, or something like that?

推荐答案

文档显示您现在可以添加：

The docs show you are now able to add:

"env": {
    "jest": true
}

到 .eslintrc 这将添加所有与你的环境相关的东西，消除了linter错误/警告。

To your .eslintrc which will add all the jest related things to your environment, eliminating the linter errors/warnings.
