在package.json中的nyc相关配置

"scripts": {
    "test:coverage": "nyc npm run test:unit","test:unit": "gulp mocha"
}
"nyc": {
    "check-coverage": true,"all": true,"extension": [
      ".js",".jsx",".ts",".tsx"
    ],"include": [
      "src/**/!(*.test.*).[tj]s?(x)"
    ],"reporter": [
      "html","lcov","text","text-summary"
    ],"report-dir": "docs/reports/coverage"
  }

gulpfile.js mocha相关部分

const SRC_DIR = path.join(__dirname,'src');
const SRC_FILES = path.join(SRC_DIR,'**','*.[jt]s?(x)');
const TEST_FILES = path.join(SRC_DIR,'*.test.[jt]s?(x)');
const MOCHA_CONFIG = {
    src: [
        TEST_FILES
    ],watchSrc: [
        SRC_FILES,TEST_FILES
    ],mocha: {
        // compilers: [
        //     'ts:ts-node/register',//     'tsx:ts-node/register'
        // ],require: [
            './tests/setup.js','ignore-styles','source-map-support/register'
        ]
    }
};
gulp.task('mocha',mocha(MOCHA_CONFIG));

tsconfig.json

{
  "compilerOptions": {
    "baseUrl": "./","rootDir": "./src","outDir": "./build","allowJs": true,"module": "commonjs","target": "es5","lib": ["es5","es6","dom"],"sourceMap": true,"inlineSourceMap": false,"inlineSources": false,"experimentalDecorators": true,"noUnusedParameters": true,"noUnusedLocals": true,"jsx": "react","moduleResolution": "node"

  ],"awesomeTypescriptLoaderOptions": {
    "useCache": true,"useBabel": true
  }
}

使用上述设置覆盖产生所有文件的结果,但它们对于TS文件是不正确的,这很可能是由于未使用源映射(即报告显示没有覆盖作为注释的行并且数字似乎也是错误的).

尝试了许多变种方法没有成功,最常见的建议之一是将“require”：[“ts-node / register”]添加到nyc配置然后我收到错误抱怨ie gulpfile.js,docs /reports/coverage/lcov-report/prettify.js和不在’rootDir’下的其他JS文件的数量是正确的但是不清楚为什么ts-node尝试处理src之外的所有文件,即使它们是在tsconfig.json中排除(仍然配置变得非常复杂).

我将不胜感激任何建议,以获得适当的TS文件覆盖率报告.
