Selenium，Arquillian，Eclipse：尝试让测试等待，直到页面完全加载

时间：2013-11-19 09:22:09

标签： java selenium junit jboss jboss-arquillian

这是我第一次在这里发帖。自从我开始使用Selenium和Arquillian来测试我们的网站仅仅几天......所以请耐心等待，因为我仍然缺乏很多知识......

我正在尝试通过键入四种不同的用户名和密码组合进行登录测试。其中三个不正确，当提交这些用户名和密码时，网站应显示错误消息。测试应检查是否确实显示了错误消息。请注意，错误消息只是同一网站中的文本框（不是弹出窗口或类似的东西......）

在输入下一个用户名/密码组合之前，我想首先刷新网站。否则，测试将始终检测前一个条目的错误消息。问题是在提交第一个用户名/密码并刷新页面后，测试才会停止。在JUnit中，我收到了以下错误消息：“org.openqa.selenium.StaleElementReferenceException：”在缓存中找不到元素 - 可能自查找以来页面已更改“。

我猜测刷新测试后应等待几秒钟直到页面完全加载..？但是，如果我使用“fluentWait”和“findElement（By.id（”user_name“））”。测试将继续运行（它不会等待），因为两个会话都是相同的网站（刷新前和刷新后），id“user_name”当然总是存在...

我真的很感激任何帮助：）

好的，对您的代码的评论很少

  • driver = new FirefoxDriver(); - 您不应该自己实例化驱动程序，@Drone会为您执行此操作
  • 你应该将你的测试分成4个方法（你正在测试4个测试用例，对吗？）并引入用@Before注释的方法，它可以在测试之间刷新页面（或者调用driver.get("baseUrl + "xxyy/login.html") - 这将使你的代码更简洁和可读
  • 你也可以提取测试方法的内容并将它放在一些util方法中，大多数代码都在每个测试中重复，所以这里的一些重构会很好：）

尝试这样，看看会发生什么：）
