问题描述

我正在尝试获取我的角度项目的代码覆盖率.我不太熟悉这些工具.我决定使用"istanbul-instrumenter-loader": "^3.0.1".我尝试从这个问题中寻求帮助:

I'm trying to get the code coverage of my angular project. I'm not very well versed with the tools. I decided to use "istanbul-instrumenter-loader": "^3.0.1". I tried taking help from this question:

1. 角度cli排除 和

And many other solutions given on the same thread. My problem is that I want to exclude spec files which I wrote for unit testing. Here is the screenshot of what I'm getting: screenshot. Please correct my mistake and feel free to ask for missing information.

推荐答案

要排除代码覆盖范围，您不仅需要指定spec文件，例如["src/app/user-card/user-card.component.spec.ts"]

To exclude code coverage, you should not just need to specify spec file such as ["src/app/user-card/user-card.component.spec.ts"]

"test": {
          "builder": "@angular-devkit/build-angular:karma",
          "options": {
            "main": "src/test.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.spec.json",
            "karmaConfig": "src/karma.conf.js",
            "codeCoverageExclude": ["src/app/user-card/user-card.component.spec.ts"],
            "styles": [
              "src/styles.scss"
            ],
            "scripts": [],
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ]
          }
        },

，而是该文件夹的整个ts文件，可用于生成覆盖率报告. (service，component等).因此，尝试使用如下所示的**.ts

but rather the entire ts files of that folder which could be used to generate coverage report. (service , component and so on). Hence try to use **.ts as shown below

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

看看这篇文章其中mock个文件被排除在覆盖范围之外
