我使用Jawin通过COM访问Windows应用程序。我的代码工作正常。我用Java编写了一个简单的测试，并按预期执行。然而，当我使用@Test注释这种方法，并通过JUnit的环境中执行它的代码抛出一个收到COMException：Jawin和JUnit
org.jawin.COMException: 80020009: Failed to get item[src=OMTE.Projects.6,guid={C9FF8402-BB2E-11D0-8475-0080C82BFA0C}]

Java代码：

}
public static void testModelId() throws COMException {

// load method is not included as the exception is thrown at getProject method

第一个作为Java应用程序运行，第二个作为JUnit4测试配置运行。
是的，测试代码似乎并不令人感兴趣，但是调用的确如此：请指定如何调用测试器方法以使其正常工作，以及在失败时如何通过Junit调用它。 –
我不确定我是否明白你的意思是通过调用。我用代码更新了原始问题，我希望这可以提供你所问的问题。 – Thanos
Java应用程序运行与Junit运行。那么：我建议你比较两种配置的准确性，找出是否有明显的差异。 –
