运行ng test时如何解决test.ts? [英] How to resolve test.ts when running ng test?

问题描述

我正在使用 Angular CLI，当我运行 ng test 时，它开始启动浏览器，然后我突然收到一个错误:

userName@UserName:~/devApp/profiles$ng test10% 构建模块 1/1 modules 0 active18 09 2017 16:16:51.891:WARN [karma]: 没有捕获的浏览器，打开 http://localhost:9876/18 09 2017 16:16:51.903:INFO [karma]:Karma v1.7.0 服务器启动于 http://0.0.0.0:9876/18 09 2017 16:16:51.903:INFO [启动器]:以无限并发启动浏览器 Chrome18 09 2017 16:16:51.915:INFO [启动器]:启动浏览器 Chrome未找到输入模块中的错误:错误:无法解析/Users/xxx/devApp/profiles/node_modules/@angular/cli/models/webpack"中的/Users/xxx/devApp/profiles/src/test.ts"-配置'

这是文件:test.ts 在我设置项目时通过 Angular CLI 生成的:

//karma.conf.js 需要这个文件，递归加载所有的 .spec 和框架文件导入 'zone.js/dist/long-stack-trace-zone';导入 'zone.js/dist/proxy.js';导入 'zone.js/dist/sync-test';导入'zone.js/dist/jasmine-patch';导入 'zone.js/dist/async-test';导入 'zone.js/dist/fake-async-test';从'@angular/core/testing'导入{getTestBed}；进口 {浏览器动态测试模块，平台浏览器动态测试来自'@angular/platform-b​​rowser-dynamic/testing';//不幸的是，`__karma__` 变量没有类型.只需将其声明为 any 即可.声明 var __karma__: any;声明 var 要求:任何；//防止 Karma 过早运行.__karma__.loaded = function () {};//首先，初始化Angular测试环境.getTestBed().initTestEnvironment(浏览器动态测试模块，平台浏览器动态测试());//然后我们找到所有的测试.const context = require.context('./', true,/\.spec\.ts$/);//并加载模块.context.keys().map(context);//最后，启动 Karma 来运行测试.__karma__.start();

angular-cli.json:

<代码> {项目": {名称":个人资料"},应用": [{"root": "src","outDir": "dist",资产":[资产"],"index": "index.html","main": "main.ts","polyfills": "polyfills.ts","test": "test.ts","tsconfig": "tsconfig.json","testTsconfig": "tsconfig.json",前缀":应用程序"，风格":["styles.css",custom_theme.scss"],脚本":[]，"environmentSource": "environments/environment.ts",环境":{"dev": "环境/environment.ts","prod": "环境/environment.prod.ts"}}],e2e":{量角器":{配置":./protractor.conf.js"}},棉绒":[{"文件": "src/**/*.ts",项目":src/tsconfig.json"},{"文件": "e2e/**/*.ts",项目":e2e/tsconfig.json"}],测试": {业力":{配置":./karma.conf.js"}},默认值":{"styleExt": "css",班级": {规格":假},成分": {规格":真实，"inlineStyle": 假,内联模板":假}}}

解决方案

错误在 karma.conf.js 文件中作为 test.ts 指向的是错误的 src 文件夹.:

<预><代码>...文件:[{ 模式:'./src/test.ts'，观看:假}],预处理器:{'./src/test.ts': ['@angular/cli']}...,

解决方案:我已将文件 test.ts 从根目录删除到 /src 文件夹:/src/test.ts 并按预期运行命令.

I'm using Angular CLI and when I run ng test, it starts launching the browser, then I suddenly get an error:

userName@UserName:~/devApp/profiles$ng test
10% building modules 1/1 modules 0 active18 09 2017 16:16:51.891:WARN [karma]: No captured browser, open http://localhost:9876/

ERROR in Entry module not found: Error: Can't resolve '/Users/xxx/devApp/profiles/src/test.ts' in '/Users/xxx/devApp/profiles/node_modules/@angular/cli/models/webpack-configs'

Here is the file: test.ts as generated via Angular CLI when I did set up the project:

// 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 var __karma__: any;
declare var 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();

angular-cli.json:

    {
  "project": {
    "name": "profiles"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": [
        "assets"

      "environments": {
        "dev": "environments/environment.ts",

      }
    }
  ],

      "project": "src/tsconfig.json"
    },
    {
      "files": "e2e/**/*.ts",
      "project": "e2e/tsconfig.json"
    }
  ],
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "class": {
      "spec": false
    },
    "component": {
      "spec": true,
      "inlineStyle": false,
      "inlineTemplate": false
    }
  }
}

解决方案

The error was in karma.conf.js file as the path to test.ts was pointing to src folder which is wrong.:

...
files: [
    { pattern: './src/test.ts', watched: false }
],
preprocessors: {
    './src/test.ts': ['@angular/cli']
}
..., 

Solution: I had remove the file test.ts from root to /src folder: /src/test.ts and it runs the command as expected.
