Android JUnit 测试因 java.lang.VerifyError 失败

Question

你好，

我一直遵循这里的指南:

http://developer.android.com/resources/tutorials/testing/helloandroid_test.html

为新的 Android 项目创建一些简单的测试用例。前几个测试用例运行良好，但现在我无法运行任何测试。这是我得到的输出示例:

    [2011-03-25 10:05:01 - application-tests] Android Launch!
[2011-03-25 10:05:01 - application-tests] adb is running normally.
[2011-03-25 10:05:01 - application-tests] Performing android.test.InstrumentationTestRunner JUnit launch
[2011-03-25 10:05:01 - application-tests] Automatic Target Mode: using existing emulator 'emulator-5554' running compatible AVD 'GalaxyTabRunning2.3'
[2011-03-25 10:05:02 - application-tests] Application already deployed. No need to reinstall.
[2011-03-25 10:05:02 - application-tests] Project dependency found, installing: application
[2011-03-25 10:05:03 - application] Application already deployed. No need to reinstall.
[2011-03-25 10:05:03 - application-tests] Launching instrumentation android.test.InstrumentationTestRunner on device emulator-5554
[2011-03-25 10:05:03 - application-tests] Collecting test information
[2011-03-25 10:05:06 - application-tests] Test run failed: java.lang.VerifyError

测试用例很简单:

/**
 * Test case to test a null input parameter to the decode method.
 * 
 */
public void testNullInputPerformCrcDecoding()
{
    try
    {
        AppProtocolDecoder.performCrcDecoding(null);
        fail("Expected IllegalArgumentException to be thrown...");
    }
    catch (IllegalArgumentException expected)
    {
        assertTrue(expected instanceof IllegalArgumentException);
    }
    catch (ProtocolException ve)
    {
        fail("Unexpected VisiProtocolException occured: " + ve);
    }
}

AppProtocolDecoder.performCrcDecoding(null);

是一个静态方法。我已经删除了它的所有代码，所以它所做的一切，字面意思是返回 null。测试总是因 java.lang.VerifyError 而失败。

这是在 Android 2.3 下使用 Eclipse 中的 Android JUnit 测试运行器。

有什么想法吗？我已经尝试重新创建测试项目和各种代码修改排列。

提前致谢!

Answer 1

您是否使用任何外部 jar ？根据我的经验，这似乎是 java.lang.VerifyError 的常见来源。

作为this answer建议您可能需要重新编译它们或通过 dx 运行它们，以便它们包含 dalvik 字节码。

编辑 - 我自己还没有处理过这个问题，我不确定执行此操作的 maven 方法，但在某些时候我认为你需要使用 dx 在你的 jar 上:

dx --dex --output=some.dex.jar some.jar

如果可能，您可以尝试在您的 jars 上手动执行此操作，看看这是否真的是问题所在，然后尝试将其集成到您的 maven 构建中。
