如何从Code Coverage Istanbul Reporter中排除模拟文件 [英] How to exclude mock files from Code Coverage Istanbul Reporter

问题描述

我有一个关于Istanbul Reporter的问题，该报告器用于在我的angular 6应用程序中报告我的单元测试范围.

I have a question regarding Istanbul Reporter used for reporting my unit testing coverage in my angular 6 application.

我的问题是:生成coverage时，我在测试文件"列表中看到了模拟，显然该模拟未经过测试，这给了我错误的coverage统计信息.

My problem is: when the coverage is rendered, I see the mocks in the tested files list and obviously the mocks aren't tested, which gives me wrong coverage stats.

这是我的一位同事设置的karma.conf文件，我想知道您是否对如何排除这些模拟文件有任何想法.

This is my karma.conf file setup by a colleague and I'd like to know if you have any idea on how to exclude those mock files.

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client:{
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, 'coverage'), reports: [ 'html', 'lcovonly' ],
      fixWebpackSourcePaths: true
    },
    angularCli: {
      environment: 'local'
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

我在StackOverflow上看到，可以通过在tsconfig.spec.json中添加排除项来完成此操作，但是即使重新运行代码覆盖率，它仍然会包含它们.

I saw on StackOverflow that it might be done by adding an exclude in the tsconfig.spec.json but even by re-running the code coverage, it still includes them.

{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
    "outDir": "../../out-tsc/spec",
    "module": "commonjs",
    "types": [
      "jasmine",
      "node"
    ],
    "typeRoots": [ "../node_modules/@types" ]
  },
  "files": [
    "src/test.ts",
    "src/polyfills.ts"
  ],
  "include": [
    "**/*.spec.ts",
    "**/*.d.ts"
  ],
  "exclude": [
    "/**/*mock*.ts"
  ]
}

我的模拟文件位于每个模块/功能的 tests /mocks文件夹中，并称为"mock-whatevertheymock.ts"

My mock files are inside tests/mocks folder in every module/feature and are called "mock-whatevertheymock.ts"

运行它的命令是

test:wc-dogs": "ng test --project=wc-dogs--code-coverage

感谢您的帮助

谢谢大家，解决方案是在angular.json中添加codeCoverageExclude选项

Thank you everyone, solution was to add the codeCoverageExclude option in angular.json

   "test": {
              "builder": "@angular-devkit/build-angular:karma",
              "options": {
                "main": "projects/wc-claims/src/test.ts",
                "polyfills": "projects/wc-claims/src/polyfills.ts",
                "tsConfig": "projects/wc-claims/tsconfig.spec.json",
                "karmaConfig": "projects/wc-claims/karma.conf.js",
                "styles": [
                  "projects/wc-claims/src/styles.css"
                ],
                "scripts": [],
                "assets": [
                  "projects/wc-claims/src/favicon.ico",
                  "projects/wc-claims/src/assets"
                ],
                "codeCoverageExclude": [
                    "/**/*mock*.ts"
                ]
              }
            },
