Angular-cli,Karma,"你可能需要一个合适的装载机___Karma___:ANY

标签: angular typescript webpack karma-runner angular2-cli

我在使用带有Karma的angular-cli进行角度2应用的单元测试时遇到了问题,我能够使量角器在e2e测试中正常工作。

我运行测试,这是我得到的

angular2 karma error

我正在一个未初始化angular-cli的angular2应用程序中运行测试。我相信这个问题围绕着tsconfig.json的一些方式。

我已经通过ng init使用angular-cli初始化了angular2应用程序,当我使用ng测试运行该应用程序时,它工作正常,我相信tsconfig是hammerjs的问题,其他js依赖项以某种方式干扰。

非常感谢任何帮助。

这是我的Karma.conf.js:



module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', 'angular-cli'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-remap-istanbul'),
      require('angular-cli/plugins/karma')
    ],
    files: [
      { pattern: './app/test.ts', watched: false }
    ],
    preprocessors: {
      './app/test.ts': ['angular-cli']
    },
    remapIstanbulReporter: {
      reports: {
        html: 'coverage',
        lcovonly: './coverage/coverage.lcov'
      }
    },
    angularCli: {
      config: '../angular-cli.json',
      environment: 'dev'
    },
    reporters: config.angularCli && config.angularCli.codeCoverage
              ? ['progress', 'karma-remap-istanbul']
              : ['progress'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};
