量角器无法使用 Firefox 启动测试

Question

我无法在 firefox 版本 56.0.1 上使用量角器启动测试。我的量角器版本是 5.1.2

exports.config = {
    allScriptsTimeout: 11000,
    specs: [
        './e2e/**/*.e2e-spec.ts'
    ],
    capabilities: {
        'browserName': 'firefox'
    },

    directConnect: true,
    baseUrl: 'http://localhost:4444/',
    framework: 'jasmine',
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function() {}
    },
};

这是错误：

你知道如何解决这个问题吗？（它在 chrome 上正常工作，但在 firefox 上显示空白页）

Answer 1

使用 geckodriver，您需要将 marionette 添加到功能中：

capabilities: {
    'browserName': 'firefox',
    'marionnette': true
},

更新：量角器 5.1.1 中引入了 open issue #4253。解决方法是手动将 directConnect 替换为 seleniumAddress 并手动启动 webdriver-manager，如 bug 中指定：

The solution is to use selenium standalone when testing with Firefox. The latest version of the selenium standalone server is compatible with Protractor's selenium JS bindings and with geckodriver. You can update and launch the standalone server with
webdriver-manager update 
webdriver-manager start 
and set seleniumAddress: http://localhost:4444

如果您选择直接连接，那么您不需要指定 base url 也不需要显式启动 webdriver 服务器。

exports.config = {
    allScriptsTimeout: 11000,
    specs: [
        './e2e/**/*.e2e-spec.ts'
    ],
    capabilities: {
        'browserName': 'firefox'
    },

    directConnect: true,
    framework: 'jasmine',
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function() {}
    },
};

在我的例子中，运行它和 'sudo' 没有用。我不得不更改文件权限，然后运行它没有 sudo。
