标签: karma-coverage

我有一个带有一些测试的Angular项目.我的版本是用Gulp编写的.我使用Karma运行测试并生成lcov报告.

然后我使用gulp-sonar插件来运行Sonar.我的声纳配置看起来像这样:

"sonar": {
  "host": {
    "url": "http://mysonar.example.com.au"
  },
  "projectKey": "sonar:advertising-test",
  "projectName": "advertising-test",
  "projectVersion": "1.0.0",
  "sources": "app/js",
  "javascript": {
    "lcov": {
      "reportPath": "reports/coverage/lcov.info"
    }
  },
  "exec": {
    "maxBuffer": "1048576"
  }
}

Sonar运行并分析代码,但在尝试使用以下内容读取lcov报告时失败:

[09:38:58] 09:38:58.322 WARN  - Problem during processing LCOV report: can't save DA data for line 0.
java.lang.IllegalArgumentException: Line with number 0 doesn't belong to file app/js/main.js
...    
[09:38:58] 09:38:58.324 WARN  - Problem during processing LCOV report: can't save DA data for line 65.
java.lang.IllegalArgumentException: Line with number 65 …

我是Angular的单元测试的新手.我得到了karma代码覆盖率的设置angular-cli.我运行了命令ng-test并打开了代码覆盖率报告.我看到了1x,3x等一起在覆盖报告我的代码行数.请找到我的报道图像.

这是我的测试用例代码 app.component.spec.ts

/* tslint:disable:no-unused-variable */

import { TestBed, async } from '@angular/core/testing';
import { AppComponent } from './app.component';

describe('AppComponent', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent
      ],
    });
  });

  it('should create the app', async(() => {
    let fixture = TestBed.createComponent(AppComponent);
    let app = fixture.debugElement.componentInstance;
    expect(app).toBeTruthy();
  }));

  it(`should have as title 'app works!'`, async(() => {
    let fixture = TestBed.createComponent(AppComponent);
    let app = fixture.debugElement.componentInstance;
    expect(app.title).toEqual('app works!');
  }));

我收到了这份覆盖摘要

我应用了 Angular 文档中指示的更改代码覆盖率：https : //angular.io/guide/testing#enable-code-coverage-report

但我总是得到同样空虚的夏天。

我的 karma.conf.js

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/singleWindow'),
      reports: ['html', 'lcovonly', …

我试图在karma框架中使用伊斯坦布尔在karma框架中获取我的打字机代码的代码覆盖率karma.conf中包含了打包的文件,并且通过karma typescript-preprocessor我们能够对打字稿代码进行单元测试和代码覆盖,但代码覆盖率报告来自转换JavaScript代码

如何获取打字稿代码的覆盖率报告？

这是我的karma.conf档案.

module.exports = function(config) {
  config.set({

    // base path, that will be used to resolve files and exclude
    basePath: '',


    // frameworks to use
    frameworks: ['jasmine'],

    preprocessors: {
        'src/**/*.ts': ['typescript', 'coverage'],
        'test/**/*.ts': ['typescript']
    },
    typescriptPreprocessor: {
        options: {
            sourceMap: false, // (optional) Generates corresponding .map file.
            target: 'ES5', // (optional) Specify ECMAScript target version: 'ES3' (default), or 'ES5'
            module: 'amd', // (optional) Specify module code generation: 'commonjs' or 'amd'
            noImplicitAny: true, // (optional) Warn on …

我一直在试图运行业力报道几天,但现在只找到一个空的空白页面如下.

这是我的配置:

var path = require('path');

var webpackConfig = require('./webpack.common');

module.exports = function (config) {
  var _config = {
    basePath: '',
    frameworks: ['jasmine'],
    files: [
      { pattern: './karma-shim.js', watched: false }
    ],
    exclude: [],
    preprocessors: {
      './karma-shim.js': ['webpack', 'sourcemap', 'coverage']
    },
    client: {
      captureConsole: false
    },
    webpack: webpackConfig,

    webpackMiddleware: {
      stats: 'errors-only'
    },

    coverageReporter: {
      dir: 'coverage/',
      reporters: [{
        type: 'json',
        dir: 'coverage',
        subdir: 'json',
        file: 'coverage-final.json'
      }]
    },

    remapIstanbulReporter: {
      src: 'coverage/json/coverage-final.json',
      reports: {
        lcovonly: 'coverage/json/lcov.info',
        html: 'coverage/html',
        'text': …

我正在研究角度 6

我在下面的代码中没有任何 else 语句。但是由于没有采用 else 路径，我无法覆盖分支。在这种情况下，我需要做什么才能获得 100% 的分支覆盖率？

 getHeaderDocumentList(documents: any) {
            if (documents) {
                documents.result.docAttachment.forEach(element => {
                    this.headerdocumentdetails.push(element.DocumentUniqueID);
                });
            }
        }

我正在使用Jasmine创建我的单元测试,我对所涉及的分支有疑问.

有谁知道为什么代码部分显示分支未被覆盖,我们可以在下面看到？

这是单元测试:

describe('MyComponent', () => {
  let component: MyComponent;
  let fixture: ComponentFixture<MyComponent>;
  let myService: MyService;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ MyComponent ],
      imports: [ MaterializeModule, FormsModule, ReactiveFormsModule, HttpModule ],
      providers: [
        MyService,
        FormBuilder
      ]
    })
    .compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(MyComponent);
    component = fixture.componentInstance;
    slotsService = TestBed.get(MyService);
    fixture.detectChanges();
  });

  function updateForm(name, surname) {
    component.myForm.controls['name'].setValue(name);
    component.myForm.controls['surname'].setValue(name);
  }

  it('should create', () => {
    expect(component).toBeTruthy();
  });
}

我们在管道中有两种不同类型的测试：单元（.net 核心）和前端（角度/业力）。他们每个人都可以通过“PublishCodeCoverageResults@1”发布代码覆盖率报告，但只有一个正面或背面。这取决于最后运行的测试。我认为最后的报道 owerwrites 以前。但是我们需要同时发布代码覆盖率。

有没有办法合并 2 个覆盖率报告，然后在一个代码覆盖率选项卡中发布它们或添加第二个选项卡？

如何使用angular2 + webpack设置karma-coverage？

我从棱角分明的快速启动webpack指南.但覆盖工具是空白的,不显示我的测试.谢谢!

我的文件夹结构是

project
|--src (project files)
|--tests (all my testfiles)

我的webpack.test.js看起来像这样

var helpers = require('./helpers');

module.exports = {
    devtool: 'inline-source-map',

    resolve: {
        extensions: ['', '.ts', '.js']
    },

    module: {
        loaders: [
            {
                test: /\.ts$/,
                loaders: ['ts']
            },
            {
                test: /\.html$/,
                loader: 'null'

            },
            {
                test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
                loader: 'null'
            },
            {
                test: /\.css$/,
                exclude: helpers.root('src', 'app'),
                loader: 'null'
            },
            {
                test: /\.css$/,
                include: helpers.root('src', 'app'),
                loader: 'null'
            }
        ]
    }
}

我的Karma.conf.js

var webpackConfig = require('./webpack.test');

module.exports = …
