Aurelia 自定义元素测试无法加载视图

Question

我在 Aurelia 测试中加载视图时遇到问题。请参考下面的示例测试代码..

import {StageComponent} from 'aurelia-testing';
import {bootstrap} from 'aurelia-bootstrapper';

describe('MyComponent', () => {
  let component;

  beforeEach(() => {
    component = StageComponent
      .withResources('src/common/my-component')
      .inView('<my-component first-name.bind="firstName"></my-component>')
      .boundTo({ firstName: 'Bob' });
  });

  it('should render first name', done => {
    component.create(bootstrap).then(() => {
      const nameElement = document.querySelector('.firstName');
      expect(nameElement.innerHTML).toBe('Bob');
      done();
    }).catch(e => { console.log(e.toString()) });
  });

  afterEach(() => {
    component.dispose();
  });
});

我将 karma 用于运行代理测试 -

proxies: {
    '/base/jspm_packages/': '/base/wwwroot/jspm_packages/'
}

在运行上面的测试之后我能够加载视图模型但是它无法加载视图并出现以下错误 -

LOG: 'Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:9876/base/src/common/my-component.html Error: XHR error (404 Not Found) loading http://localhost:9876/base/src/common/my-component.html Error loading http://localhost:9876/base/src/common/my-component.html!http://localhost:9876/base/jspm_packages/github/systemjs/plugin-text@0.0.8.js Error loading http://localhost:9876/base/src/common/my-component.html!template-registry-entry'

提前感谢您的帮助！

更新 --> Karma.conf.js 文件

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

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',

    },

    // list of files / patterns to load in the browser
    files: [],

    autoWatch: true,

    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false
  })
}

可能是这一行：

  serveFiles: ['src/**/*.js'],

实际上应该是这样的：

  serveFiles: ['src/**/*.js', 'src/**/*.html']

通常您的 html 会与组件的 js 捆绑在一起，但在这种情况下，您直接为 html 提供服务。
