马拉松 | Java Driver 在 JNLP 应用程序上 - 无顶层 Window 可用

Marathon | Java Driver on a JNLP application - No Top Level Window Available

我是 Marathon 的新手并且 Java Driver。我在一家软件测试公司工作,我们最近开始研究 Marathon 和 Java Driver,将其用作 Java 应用程序的自动化工具。我们在内部测试中取得了成功,但在让 Java Driver 在我们的主要客户端上工作时遇到了一些麻烦(这个客户端是我们测试使用 Marathon 的原因)。

我会尽可能详细地解释所有内容,但请记住,我对该客户端的访问权限有限(这是一个真正的挑战),因此一些信息可能不可用。

我们正在使用 JNLP 应用程序。我们已经能够使其在录制和回放模式下正确地与 MarathonITE 一起工作。为了让它工作,我们必须:

所以,使用 Marathon 进行录制和回放是可行的,我们的问题是我们还需要能够通过 Java Driver 做一些事情,而这正是我们还没有做到的可以开始了。

这是我们使用 Java Driver:

启动应用程序的代码
JavaProfile profile = new JavaProfile (LaunchMode.JAVA_WEBSTART);
profile.setJNLPPath(applicationPath);
profile.setStartWindowTitle("Topaz Client");
profile.setJavaHome("C:\Program Files (x86)\Java\jdk1.8.0_144");

JavaDriver driver = new JavaDriver(profile);

它使用与 MarathonITE 相同的数据,我们甚至设置了 StartWindowTitle 和 JavaHome,就像我们使用 MarathonITE

一样

应用程序启动,之后我们需要开始寻找要与它们交互的元素。

List<WebElement> elements = driver.findElements(By.className("javax.swing.JTextField"));

这是它崩溃的地方,报告 JavaAgentException:No 顶级 window 可用

这是异常的完整日志(此日志文件的某些部分来自我们自己的代码)

关于一些附加信息,我们正在使用的机器有:

在我们的项目中我们使用:

我曾尝试从 JDK 切换到 JRE(均适用于 MarathonITE),但均无效。尝试使用不同的 object 识别方式,甚至像 className(".*") 这样的方式,但得到了相同的结果。

据我所知,异常是 three,因为 Java Driver 没有找到 Window 工作,尽管应用程序已正确启动。

我真的不知道如何处理这个问题。同样的代码适用于其他 JNLP 应用程序。如果有人对我有什么建议可以让它发挥作用,我将不胜感激。

谢谢

  1. Java 版本没有问题。
  2. 您的应用程序可能有多个 Windows 在所需的 window 出现之前出现,因此他丢失了他的顶级组件。

只需使用切换到 window 方法并在调用 findElements 之前传递 tile。这应该可以解决问题。

driver.switchTo().window("Topaz Client");
