Simpe Android JUnit测试在Eclipse中挂起

我一直在阅读关于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);
    }

}

然后它挂起，下面是JUnit视图：

已尝试调试，但从未达到TestPremissions（）。

谢谢。

只需要在拆卸时调用super（）

它可能挂在setUp（）中，安装程序在每个单元测试方法之前执行。谢谢，您让我查看代码。我忘了在tearDown（）中调用super；我想你应该把你的拆除方法作为回答。谢谢！当教程不需要super.tearDown（）时，一定是片段或其他东西让我需要它。
