How to import "describe" and "it" from mocha in TypeScript?
提问by Ace
By default, when importing mochain TypeScript, it brings in describeand it(and some others) into the global namespace.
默认情况下，mocha在 TypeScript 中导入时，它会将describe和it（以及其他一些）引入全局命名空间。
Is there a way to bring in specific imports like import {describe, it} from 'mocha'?
有没有办法引入特定的进口产品import {describe, it} from 'mocha'？

Install mocha and its types:
安装 mocha 及其类型：
npm install mocha --save-dev
npm install @types/mocha --save-dev
Then, simply import mocha in your test files:
然后，只需在您的测试文件中导入 mocha：
import 'mocha';
describe('my test', () => {
it('does something', () => {
// your test
});
});

Since TypeScript 2.0, you can add mochato the typesconfiguration of your tsconfig.jsonand it will always be loaded:
从 TypeScript 2.0 开始，您可以添加mocha到types您的配置中tsconfig.json，它将始终加载：
{
"compilerOptions": {
"types": [
"mocha"
]
}
}

I was having issues with errors and warnings, the problem stemmed from me renaming tsconfig.jsonto something else which makes Visual Studio Code enter "File Scope" instead of "Explicit Project". That made it impossible to import itwithout a red squiggly. Now that I've renamed the config back to tsconfig.jsonthen import 'mocha';works as Eryk mentioned.
我遇到了错误和警告问题，问题源于我重命名tsconfig.json为其他内容，这使 Visual Studio Code 输入“文件范围”而不是“显式项目”。这使得it没有红色波浪线就无法导入。现在我已经将配置重命名为tsconfig.json然后import 'mocha';像 Eryk 提到的那样工作。
