我已从developer.android
下载此代码public class SpinnerTestActivity extends
ActivityInstrumentationTestCase2<SpinnerActivity> {
private SpinnerActivity mActivity;
private Spinner mSpinner;
private SpinnerAdapter mPlanetData;
public static final int ADAPTER_COUNT = 9;
public static final int INITIAL_POSITION = 0;
public static final int TEST_POSITION = 5;
private String mSelection;
private int mPos;
public SpinnerTestActivity() {
super("com.android.example.spinner", SpinnerActivity.class);
} // end of SpinnerActivityTest constructor definition
@Override
protected void setUp() throws Exception {
super.setUp();
setActivityInitialTouchMode(false);
mActivity = getActivity();
mSpinner = (Spinner) mActivity
.findViewById(com.android.example.spinner.R.id.Spinner01);
mPlanetData = mSpinner.getAdapter();
} // end of setUp() method definition
public void testPreConditions() {
assertTrue(mSpinner.getOnItemSelectedListener() != null);
assertTrue(mPlanetData != null);
assertEquals(mPlanetData.getCount(), ADAPTER_COUNT);
} // end of testPreConditions() method definition
public void testSpinnerUI() {
mActivity.runOnUiThread(new Runnable() {
public void run() {
mSpinner.requestFocus();
mSpinner.setSelection(INITIAL_POSITION);
} // end of run() method definition
} // end of anonymous Runnable object instantiation
); // end of invocation of runOnUiThread
this.sendKeys(KeyEvent.KEYCODE_DPAD_CENTER);
for (int i = 1; i <= TEST_POSITION; i++) {
this.sendKeys(KeyEvent.KEYCODE_DPAD_DOWN);
} // end of for loop
this.sendKeys(KeyEvent.KEYCODE_DPAD_CENTER);
mPos = mSpinner.getSelectedItemPosition();
mSelection = (String) mSpinner.getItemAtPosition(mPos);
TextView resultView = (TextView) mActivity
.findViewById(com.android.example.spinner.R.id.SpinnerResult);
String resultText = (String) resultView.getText();
assertEquals(resultText, mSelection);
}
}
我的问题是:如何调用testSpinnerUI?来自哪里?我已阅读junit文档但无法弄清楚..谢谢!
答案 0 :(得分:0)
测试用例的生命周期基本上是这样的:construction
,setUp()
,tests run
,tearDown()
和destruction
。 setUp()
方法用于执行所有特定测试使用的任何常规初始化。在测试用例中运行的每个测试都是作为自己的方法实现的,其中方法名称以“test”开头。然后使用tearDown()
方法取消初始化setUp()
方法获取的任何资源。
每个特定的测试都有自己的方法,以“test”开头 - “test”方法名称前缀区分大小写!
我最初的问题是测试方法是如何运行的,因为没有人调用它。但是从上面的测试中,每种方法都应该进行测试,以便进行识别。
