简单的Android JUnit测试在Eclipse中挂起

Question

我一直在关注Android测试的书并实施了这个样本：

public class TemperatureConverterActivityTests extends
        ActivityInstrumentationTestCase2<TemperatureConverterActivity> {

    private TemperatureConverterActivity mActivity;

    private EditText mCelsius;
    private EditText mFarenheit;

    public TemperatureConverterActivityTests() {
        this("TemperatureConverterActivityTests");
    }

    public TemperatureConverterActivityTests(String name) {
        super(TemperatureConverterActivity.class);
        setName(name);
    }

    protected void setUp() throws Exception {
        super.setUp();
        mActivity = getActivity();

        mCelsius = (EditText) mActivity
                .findViewById(org.mighter.tc.R.id.celsius);
        mFarenheit = (EditText) mActivity
                .findViewById(org.mighter.tc.R.id.farenheit);
    }

    protected void tearDown() throws Exception {
    }

    public final void testPreconditions() {
        assertNotNull(mActivity);
    }

    public final void testHasInputFields() {
        assertNotNull(mCelsius);
        assertNotNull(mFarenheit);
    }

}

然而，测试没有完成。

我在控制台中获得了什么：

Android Launch!
adb is running normally.
Performing android.test.InstrumentationTestRunner JUnit launch
Automatic Target Mode: Several compatible targets. Please select a target device.
Uploading TemperatureConverterTest.apk onto device '80A358103041548074'

然后它挂起，这是JUnit视图：

LogCat的唯一信息：

尝试调试，但它永远不会到达testPreconditions（）。 感谢。

只需要在tearDown（）中调用super;
