Question

问题

我试图让AppVeyor使用Protractor和Selenium-webdriver运行一些e2e测试。

在我的本地机器上一切正常，但是当在AppVeyor量角器上进行构建和测试时，由于selenium-webdriver中的一个未找到的方法，代码1退出了。我试图获得有关错误消息的一些信息，但我的搜索并没有让我到任何地方。大多数结果来自使用Java的后端测试。

以下是构建日志的片段：

selenium服务器正在运行，测试通过，但是当服务器即将关闭时，会发生错误。

设置

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

量角器使用gulp-protractor插件执行gulp任务，并且量角器配置中定义了selenium独立jar，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。控制台中的部署日志记录非常响亮，并且无法在AppVeyor上进行配置。

本地日志信息

如上所述，我的本地计算机上的一切运行正常。这是量角器运行的日志。

使用以下java运行时引擎参数解决此问题

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