用于开玩笑的 vscode 自动类型获取 [英] vscode automatic type acquisition for jest

问题描述

我有 vscode 1.9 并且我想有用于玩笑测试的智能感知.问题是 describe、it、expect 等在 jest 中是全局可用的，你不需要 import 它们在您的测试文件中.所以 vscode 不会为他们显示智能感知.

I have vscode 1.9 and I want to have intellisense for jest tests. The problem is that describe, it, expect etc are globally available in jest and you don't need to import them in your test files. So vscode will not show intellisense for them.

是否有全局变量自动获取类型的配置?

Is there any configuration for globals for automatic type acquisition?

推荐答案

在这种情况下，您有几个选择:

You have a few options in this case:

将 jest 添加到您的 package.json:

"dependencies": {
  "jest": "^18.1.0"
}

这仅在您使用 JavaScript 并且没有 tsconfig.json 时才有效.

This only works if you are working JavaScript and do not have a tsconfig.json.

安装@types/jest

$ npm install -D @types/jest

这应该适用于 JavaScript 和 TypeScript 项目.但是 @types 但可能被 jsconfig.json/tsconfig.json 禁用:http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

This should work for both JavaScript and TypeScript projects. However @types but may be disabled by a jsconfig.json/tsconfig.json: http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

在工作区的根目录中创建一个 jsconfig.json 文件以专门包含 jest:

Create a jsconfig.json file in the root of your workspace to specifically include jest:

{
    "typeAcquisition": {
        "include": [
            "jest"
        ]
    }
}

这仅适用于启用自动类型获取的 JavaScript 项目.

This will only work for JavaScript projects when automatic typings acquisition is enabled.

所有这些都应该允许 VSCode 在没有 import 或 require

All of these should allow VSCode to pick up jest's typings without an import or require
