使用 Mockito 1.9.5 和 DexMaker-Mockito-1.0 的验证错误

问题描述

像许多其他人一样，我很高兴听到 dexmaker-android 组合 仅在针对真实设备运行插桩测试时 100% 工作.

在真实设备上运行测试不会出现此故障.

Like many others I was excited to hear that Mockito now works with Android and followed this tutorial to see it with my own eyes. Everything seemed fan-flapping-tastic and I got underway incorporating the mocking solution into my Android Test Project...

The error

However, on setting up my application's test project to leverage the mockito-all-1.9.5, dexmaker-1.0 and dexmaker-mockito-1.0 jars I encountered a problem with my very first test case. Precisely this problem in fact. The part that I would like assistance on is;

Caused by: java.lang.VerifyError: org/mockito/cglib/core/ReflectUtils
at org.mockito.cglib.core.KeyFactory$Generator.generateClass(KeyFactory.java:167)
at org.mockito.cglib.core.DefaultGeneratorStrategy.generate(DefaultGeneratorStrategy.java:25)

at org.mockito.cglib.proxy.Enhancer.<clinit>(Enhancer.java:70)

I have been informed that this "simply doesn't quite work yet" since the stack trace implies that the DexMaker jar is not being used - reference this response. However, I am suspicious that I am doing something wrong with respect to my project set-up so I'm looking to draw from the collective knowledge base here to see if indeed this is user error or a beta-bug.

My Android Test Project set-up

Please find below a screenshot of my test project's configuration. The project was created via the Android Wizard and shares no special features other than the inclusion of the Mockito and DexMaker jars (mentioned above) under the libs directory.

The Test

Never mind the content of the test (the test fails before the unit test is executed) the set-up is as described below;

public class TestSpotRatingCalculator extends InstrumentationTestCase {
  @Mock
  private AService aService; // Changed the service names being used here - not important.
  @Mock
  private BService bService;
  @Mock
  private CService cService;
  @Mock
  private DService dService;

  /**
   * @see android.test.AndroidTestCase#setUp()
   */
  @Override
  protected void setUp() throws Exception {
    super.setUp();
    MockitoAnnotations.initMocks(this);  // Failure here with aforementioned stacktrace...
  }

If anyone out there has an idea what is wrong then please sound-off here.

As hinted at here the dexmaker-android combo only works 100% when the instrumented tests are run against a real device.

Running the tests against a real device do not exhibit this failure.
