那么就可以做Android单元测试了，给出下面的实例；
1.用AndroidTestCase;
Java代码
public class SdcardTest extends AndroidTestCase { public void test1(){ // Log.v() File f=new File("/sdcard"); String[] l=f.list(); this.assertTrue(f.exists()); this.assertTrue(f.isDirectory()); this.assertTrue(f.list().length>0); } } public class SdcardTest extends AndroidTestCase { public void test1(){ // Log.v() File f=new File("/sdcard"); String[] l=f.list(); this.assertTrue(f.exists()); this.assertTrue(f.isDirectory()); this.assertTrue(f.list().length>0); } }2.用ActivityUnitTestCase
Java代码
public class ForwardingTest extends ActivityUnitTestCase
< Forwarding> {private Intent mStartIntent;
private Button mButton;
public ForwardingTest() {
super(Forwarding.class);
}
@Override
protected void setUp() throws Exception {
super.setUp();
// In setUp, you can create any shared test data,
or set up mock components to inject// into your Activity. But do not call startActivity()
until the actual test methods.mStartIntent = new Intent(Intent.ACTION_MAIN);
}
/**
* The name 'test preconditions' is a convention
to signal that if this* test doesn't pass, the test case was not set up
properly and it might* explain any and all failures in other tests.
This is not guaranteed* to run before other tests, as junit uses
reflection to find the tests.*/
@MediumTest
public void testPreconditions() {
startActivity(mStartIntent, null, null);
mButton = (Button) getActivity().findViewById(R.id.go);
assertNotNull(getActivity());
assertNotNull(mButton);
}
/**
* This test demonstrates examining the way that
activity calls startActivity() to launch* other activities.
*/
@MediumTest
public void testSubLaunch() {
Forwarding activity = startActivity(mStartIntent, null, null);
mButton = (Button) activity.findViewById(R.id.go);
// This test confirms that when you click the
button, the activity attempts to open// another activity (by calling startActivity)
and close itself (by calling finish()).mButton.performClick();
assertNotNull(getStartedActivityIntent());
assertTrue(isFinishCalled());
}
/**
* This test demonstrates ways to exercise the Activity's life cycle.
*/
@MediumTest
public void testLifeCycleCreate() {
Forwarding activity = startActivity(mStartIntent, null, null);
// At this point, onCreate() has been called, but nothing else
// Complete the startup of the activity
getInstrumentation().callActivityOnStart(activity);
getInstrumentation().callActivityOnResume(activity);
// At this point you could test for various configuration
aspects, or you could// use a Mock Context to confirm that your activity
has made certain calls to the system// and set itself up properly.
getInstrumentation().callActivityOnPause(activity);
// At this point you could confirm that the activity
has paused properly, as if it is// no longer the topmost activity on screen.
getInstrumentation().callActivityOnStop(activity);
// At this point, you could confirm that the activity
has shut itself down appropriately,// or you could use a Mock Context to confirm that your
activity has released any system// resources it should no longer be holding.
// ActivityUnitTestCase.tearDown(), which is always
automatically called, will take care// of calling onDestroy().
}
