Simpe Android JUnit测试在Eclipse中挂起

Question

我一直在关注Android测试的书并实现了这个示例:

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);
    }

}

但是,测试没有完成.

我在控制台中获得的内容:

Android Launch!
adb is running normally.

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().谢谢.

只需要在tearDown()中调用super即可；
