【问题描述】：

我一直在关注有关 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。

我在控制台中得到的信息：

Android Launch!
adb is running normally.
Performing android.test.InstrumentationTestRunner JUnit launch

然后它挂了，这里是 JUnit 视图：

来自 LogCat 的唯一信息：

尝试调试，但始终无法达到 testPreconditions()。谢谢。

【问题讨论】：

可能挂在setUp()中，setUp在每个单元测试方法之前执行
谢谢，你指点我研究代码。我忘了在 tearDown() 中调用 super；
我认为你应该发布你的拆解方法作为答案

标签： android eclipse unit-testing junit

【解决方案1】：

只需要在tearDown()中调用super；

【讨论】：

谢谢！一定是教程不需要时让我需要 super.tearDown() 的片段或东西。
