Android单元测试




关键词:

  如果你要测试的是Activity或者Service,就用ActivityUnitTestCase,ServiceTestCase。否则选择:AndroidTestCase。

  在做Android单元测试以前,你需要创建一个新的项目,把要测试的项目包含到java build path中来。项目中的AndroidManifest.xml如下(这里假设你的your.test.package里面包含你的 tests,your.work.package包含被测试的类):

  Xml代码:

  < ?xml version="1.0" encoding="utf-8"?>

  < manifest xmlns:android=

  "http://schemas.Android.com/apk/res/Android"

  package="your.tests.package">

  < application>

  < uses-library Android:name="Android.test.runner" />

  < /application>

  < instrumentation Android:name=

  "Android.test.InstrumentationTestRunner"

  Android:targetPackage="your.work.package"

  Android:label="Tests for Api Demos."/>

  < /manifest>

  < ?xml version="1.0" encoding="utf-8"?>

  < manifest xmlns:android=

  "http://schemas.Android.com/apk/res/Android"

  package="your.tests.package">

  < application>

  < uses-library Android:name="Android.test.runner" />

  < /application>

  < instrumentation Android:name=

  "Android.test.InstrumentationTestRunner"

  Android:targetPackage="your.work.package"

  Android:label="Tests for Api Demos."/>

  < /manifest>

  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(). } }
