ng 测试在使用 firefox 浏览器时出现错误

Question

运行 ng 测试时出现以下错误，（添加了 Karama.conf.js 的 Firefox 浏览器）无法加载浏览器"Firefox"：它没有注册！也许您缺少一些插件？

Answer 1

检查您的 karma 配置文件以查看列出的 firefox 插件，

插件：[ 'karma-junit-reporter', 'karma-chrome-launcher', 'karma-firefox-launcher' ],

Answer 2

添加以下依赖项可解决问题：

plugins: [
      require('core-js/es6/promise'),
      require('karma-jasmine'),
      require('karma-ie-launcher'),
      require('karma-chrome-launcher'),
      require('karma-firefox-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma'),
      'karma-spec-reporter'
    ],
