关闭 selenium-webdriver 连接时量角器测试失败

Question

问题

我正在尝试让 AppVeyor 运行使用量角器和 Selenium-webdriver 进行一些 e2e 测试。

在我的本地机器上一切正常，但在 AppVeyor protractor 上构建和测试时似乎由于在 selenium-webdriver 中未找到方法而以代码 1 退出。我试图获取有关错误消息的一些信息，但我的搜索并没有让我找到任何地方。大部分结果来自 Java.

的后端测试

这是构建日志的片段：

selenium 服务器正在运行ning，测试通过但是当服务器即将关闭时出现错误。

设置

在构建开始时，我运行 npm install 又运行s node_modules\.bin\webdriver-manager update --standalone 作为安装后脚本。

Protractor 运行带有 gulp 任务和 gulp-protractor 插件，selenium 独立 jar 是在量角器配置中定义的，如下所示：

exports.config = {
    seleniumServerJar: '../node_modules/protractor/selenium/selenium-server-standalone-2.47.1.jar',

    specs: ['Tests/**/*e2e.spec.js'],

    resultJsonOutputFile: 'results-protractor.json',

    allScriptsTimeout: 30000
};

完整的构建日志可以在这里看到：https://ci.appveyor.com/project/Crevil/kitos/build/1.0.187 为嘈杂的日志道歉。部署日志在控制台中非常响亮，并且无法在 AppVeyor afaict 上配置。

本地日志信息

如前所述，运行在我的本地计算机上一切正常。这是量角器的日志运行ning.

此问题已通过 java 运行时引擎的以下参数解决

localSeleniumStandaloneOpts: {
        args: ['-Djna.nosys=true']
},
