Android的JUnit測試與java.lang.VerifyError的

Question

阿羅哈失敗，

我一直在關注這裏的準則：

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

要爲新的Android項目創建一些簡單的測試案例。前幾個測試用例工作正常，但現在我無法運行任何測試。這是我得到的輸出的例子：

[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 

測試用例是非常簡單的：

/** 
* 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); 

是一個靜態方法。我已經從它中刪除了所有的代碼，所以它的確從字面上返回null。該測試總是會因java.lang.VerifyError失敗。

這是在Android 2.3下使用Eclipse中的Android JUnit Test runner。

任何想法？我試過重新創建測試項目和各種代碼修改的排列。

在此先感謝！

我使用Maven類的依賴。以下是我通過Maven提供的庫：

Answer 1

您是否在使用任何外部罐子？根據我的經驗，這似乎是java.lang.VerifyError的常見來源。

由於this answer建議您可能需要重新編譯它們或通過dx運行它們，以便它們包含達爾維克字節碼。

編輯 - 我還沒有處理這個自己，我不知道Maven的方式做到這一點，但在某些時候，我認爲你需要在你的罐子使用dx：

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

如果可能的話，你可以嘗試在你的罐子上手工做這件事，看看它是否真的存在問題，然後嘗試將它集成到你的Maven構建中。

Answer 2

如果您在主項目中使用外部庫，則應將它們導出到測試中。

Answer 3

我最終做的只是刪除使用這些庫的代碼。在大多數情況下，這樣做很微不足道。

Answer 4

從19.1.0升級我的生成工具21.1.2固定我的測試失敗與java.lang.VerifyError

apply plugin: 'android' 

android { 
    compileSdkVersion 19 
    buildToolsVersion '21.1.2' 
    defaultConfig { 
     minSdkVersion 15 
     targetSdkVersion 19 
     versionCode 1 
     versionName "2.0" 
     testInstrumentationRunner "android.test.InstrumentationTestRunner" 
    } 

    buildTypes { 
     release { 
      minifyEnabled true 
      debuggable false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' 
     } 
     debug { 
      debuggable true 
      minifyEnabled false 
      multiDexEnabled false 
      testCoverageEnabled = true 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
}
