selenium - 我可以为 Protractor 设置更长的超时时间以连接到 selenium 驱动程序吗？

Question

远程运行我的 Protractor 测试 (jenkins) 有时会导致超时错误。那不是确定性的。

Starting selenium standalone server...
[launcher] Running 1 instances of WebDriver
[launcher] Process exited with error code 1

/opt/jenkins.dir/workspace/my-jenkins-job/integration-test/ui/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/promise.js:1761
      throw error;
            ^
Error: Timed out waiting for the WebDriver server at http://10.97.193.53:4455/wd/hub

然而，当我在我的 mac 上本地运行测试时，没有问题，测试运行完美。

我曾尝试在远程机器上手动启动 selenium 服务器，我发现有时它会立即运行，有时我必须等待一分钟。

我的问题是:有什么方法可以让 Protractor 等待 webdriver 连接更长时间吗？

环境细节

• 机器:Red Hat 4.4.7-11
• Protractor 版本:1.8.0
• Selenium 服务器独立版:2.45.0

您可以使用 driver.wait 函数指定它。

var webdriver = require('selenium-webdriver');
var protractor = require('protractor');

var driver = new webdriver.Builder().usingServer("seleniumAddress").build();
var browser = protractor.wrapDriver(driver);

browser.driver.wait(driver.getWindowHandle(), 5000, 'Server should start within 5 seconds');
