Angular中伊斯坦布尔覆盖报告中的标记异常

【中文标题】Angular中伊斯坦布尔覆盖报告中的标记异常【英文标题】:marker abnormal in istanbul coverage report in Angular 【发布时间】:2019-02-01 20:15:24 【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:
相关库版本为: "@angular/core": "^6.1.0", "@angular/cli": "^6.1.1", "@angular/compiler-cli": "^6.1.0", “茉莉花核”:“~3.1.0”, "jasmine-spec-reporter": "~4.2.1", “业力”:“~2.0.5”, “karma-chrome-launcher”:“~2.2.0”, “业力-cli”:“~1.0.1”, “业力覆盖-伊斯坦布尔记者”:“^2.0.1”, “业力茉莉花”:“~1.1.0”, "karma-jasmine-html-reporter": "^1.2.0",
test.ts
是:
// 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();
package.json

我使用的命令行是:
ng test rubik-frontend --code-coverage
谢谢!
【问题讨论】:
你到底在运行什么命令?请发布您的test.ts
以及您的 package.json
脚本。我记得通过删除我的测试命令的--source-map false
解决了这个问题。当您的测试遇到错误或异常时,也会发生这种情况。
@trichetriche 感谢您的回复。我已经更新了我的帖子。
【参考方案1】:
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。
【讨论】:
我遇到了同样的问题,将--source-map=true
添加到命令中即可解决。不知道为什么默认情况下不启用。以上是关于Angular中伊斯坦布尔覆盖报告中的标记异常的主要内容,如果未能解决你的问题,请参考以下文章
