使用 karma 在无头模式下启动 Firefox

Question

我使用Angular和'业力'。我的 conf 看起来像这样：

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine', '@angular-devkit/build-angular'],
        plugins: [
            require('karma-jasmine'),
            require('karma-jasmine-html-reporter'),
            require('karma-coverage-istanbul-reporter'),
            require('@angular-devkit/build-angular/plugins/karma'),
            require('karma-firefox-launcher')
        ],
        client: {
            clearContext: false // leave Jasmine Spec Runner output visible in browser
        },
        coverageIstanbulReporter: {
            dir: require('path').join(__dirname, '../coverage'),
            reports: ['html', 'lcovonly'],
            fixWebpackSourcePaths: true
        },
        reporters: ['progress', 'kjhtml'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: true,
        browsers: ['FirefoxHeadless'],
        customLaunchers: {
            'FirefoxHeadless': {
                base: 'Firefox',
                flags: [
                    '-headless',
                ],
            }
        },
        singleRun: true
    });
};

但是，当我发出命令时：

ng t

我的 Firefox 浏览器无法启动。在控制台中，我看到消息：

我的版本：

"karma": "~1.7.1"
"karma-firefox-launcher": "^1.1.0"
"karma-jasmine": "~1.1.1"
Firefox 64.0

我不明白为什么会这样。为什么浏览器不能启动？在Chrome浏览器中没有这样的问题，但我需要的正是Firefox.

我解决了这个问题。问题是公司代理服务器。我添加karma.conf.js：

customLaunchers: {
            'FirefoxHeadless': {
                base: 'Firefox',
                flags: [
                    '-headless',
                ],
                prefs: {
                    'network.proxy.type': 0
                }
            }
        },

它奏效了。
