angular - Angular中伊斯坦布尔覆盖报告中的标记异常

问题描述

我使用 Karma 运行单元测试并生成覆盖率报告，但是，彩色部分（如这些红色代码）似乎异常移动，如下所示：

在此处输入图像描述 在此处输入图像描述

相关库版本为：
“@angular/core”：“^6.1.0”、
“@angular/cli”：“^6.1.1”、
“@angular/compiler-cli”：“^6.1.0”、
“jasmine-core”：“~3.1.0”，
“jasmine-spec-reporter”：“~4.2.1”，
“karma”：“~2.0.5”，
“karma-chrome-launcher”：“~2.2 .0",
"karma-cli": "~1.0.1",
"karma-coverage-istanbul-reporter": "^2.0.1",
"karma-jasmine": "~1.1.0",
"karma- jasmine-html-reporter": "^1.2.0",

是test.ts：

// This file is required by karma.conf.js and loads recursively all the .spec and framework files

import 'zone.js/dist/long-stack-trace-zone';
import 'zone.js/dist/proxy.js';
import 'zone.js/dist/sync-test';
import 'zone.js/dist/jasmine-patch';
import 'zone.js/dist/async-test';
import 'zone.js/dist/fake-async-test';
import { getTestBed } from '@angular/core/testing';
import {
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';

// Unfortunately there's no typing for the `__karma__` variable. Just declare it as any.
declare const __karma__: any;
declare const require: any;

// Prevent Karma from running prematurely.
__karma__.loaded = function () {};

// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting()
);
// Then we find all the tests.
const context = require.context('./', true, /\.spec\.ts$/);
// And load the modules.
context.keys().map(context);
// Finally, start Karma to run the tests.
__karma__.start();

我使用的命令行是： ng test rubik-frontend --code-coverage

谢谢 ！

标签： angularunit-testingjasminekarma-jasmineistanbul

解决方案

请尝试使用

ng test rubik-frontend --code-coverage true --source-map true

据我所知，这解决了我的问题。我不确定，为什么它默认不使用源映射。
