nyc 覆盖没有看到在快速路线上使用的导入功能

如何解决nyc 覆盖没有看到在快速路线上使用的导入功能

我正在努力覆盖作为导入函数传递给快速路由的打字稿代码：

// FILE: router.ts
import { reachedapi } from "reachedapi";
router.get("/test",reachedapi);

// FILE: reachedapi.ts
export function reachedapi(req: Request,res: Response) {
    res.json({ message: "Reached API!"});
}

reachedapi.ts 在这种情况下没有代码覆盖。而如果我将所有内容都放在同一个文件中，则完全覆盖：

// FILE: routes.ts
function reachedapi(req: Request,res: Response) {
    res.json({ message: "Reached API!"});
}
router.get("/test",reachedapi);

这些是我的 nyc、mocha 配置文件和 package.json 中的命令：

// FILE: .mocharc.json
{
  "extension": ["ts"],"timeout": 5000,"exit": true,"color": true,"require": ["ts-node/register","source-map-support/register"],"recursive": true
}

// FILE: .nycrc.json
{
    "extends": "@istanbuljs/nyc-config-typescript","reporter": [
        "html","text-summary"
    ],"extension": [
        ".ts",".tsx"
    ],"exclude": [
        "**/*.d.ts","test/**/*","build/**/*"
    ],"include": [
        "src/**/*.ts"
    ],"check-coverage": false,"sourceMap": true,"instrument": true,"all": true,"cache": false
}

// FILE: package.json
"test": "tsc && nyc --reporter=lcov --reporter=text-summary mocha 'test/**/*.ts'",

在更复杂的情况下，我有以下路线：

router.post('/user/:user/changePassword',bindUser,auth,val,checkValidation,changePassword);

尽管调用了 bindUser、auth、checkValidation 或 changePassword 函数，但它们都没有被覆盖。
