使用 mocha 进行打字稿单元测试找不到音频类型

如何解决使用 mocha 进行打字稿单元测试找不到音频类型

我刚开始使用 typescript 单元测试，但是在使用 mocha 设置单元测试时发现了一个问题。基本上在我的测试中，我引用了一个音频类型，但它失败并出现错误：

  1) test suite
       test 1:
     ReferenceError: Audio is not defined
      at Context.<anonymous> (test\softphone.spec.ts:6:21)
      at processImmediate (internal/timers.js:461:21)

我怎样才能让它找到那种类型？

我需要能够创建一个 Audio 对象（即使是空的）来构建我要测试的类型的实例，但我无法让测试找到 Audio 类型定义。 这些是我的配置文件：

package.json

{
    "name": "test project","version": "0.0.1","description": "test project","scripts": {
        "compile" : "./node_modules/.bin/tsc","test": "npm run compile && mocha -r ts-node/register test/**/*.spec.ts","build": "npm run test && webpack --config webpack.config.js"
    },"directories": {
        "src": "./src","test": "./test"
    },"dependencies": {
        "sip.js": "0.19.0","typescript-logging": "^1.0.0"
    },"devDependencies": {
        "@types/chai": "^4.2.15","@types/mocha": "^8.2.0","@types/typescript": "^2.0.0","chai": "^4.3.0","mocha": "^8.3.0","ts-loader": "^8.0.14","ts-mockito": "^2.6.1","ts-node": "^9.1.1","typescript": "^4.1.3","webpack": "^4.46.0","webpack-cli": "^4.5.0"
    } }

tsconfig.json

{
  "compilerOptions": {
    "outDir": "dist","target": "es2019","lib": [
      "es2019","dom"
    ],"module": "commonjs","esModuleInterop": true,"strict": true,"sourceMap": true,"types": [
      "mocha","chai","ts-mockito","typescript"
    ]
  }
}

.mocharc.json

{
    "extension": [
        "ts"
    ],"spec": "test/**/*.spec.ts","require": "ts-node/register"
}

这是测试文件：

import { assert } from "chai"

describe("test suite",() => {
    it("test 1",() => {
        let audio = new Audio()
    });
    it("test 2",() => {
        assert.equal(1,1)
    });
});
