UIautomator Test Case Android

I'm working with UiAutomator, but I unable to extend my class with UIAutomatorTestCase, Also I had added the jar files ie UIAutomator jar files and JUnit3 lib. I'm getting error in this class And also i want to knw how to build the testcases for that application plus How can I run the test cases from my application programmatically? if no then how i can run these test cases. ``` package com.example.test; import junit.framework.TestCase; public class UiAutomatorTestCase extends TestCase { private static final String DISABLE_IME = "disable_ime"; private static final String DUMMY_IME_PACKAGE = "com.android.testing.dummyime"; private UiDevice mUiDevice; private Bundle mParams; private IAutomationSupport mAutomationSupport; private boolean mShouldDisableIme = false; @Override protected void setUp() throws Exception { super.setUp(); mShouldDisableIme = "true".equals(mParams.getString(DISABLE_IME)); if (mShouldDisableIme) { setDummyIme(); } } @Override protected void tearDown() throws Exception { if (mShouldDisableIme) { restoreActiveIme(); } super.tearDown(); } /** * Get current instance of {@link UiDevice}. Works similar to calling the static {@link UiDevice#getInstance()} from anywhere in the test classes. */ public UiDevice getUiDevice() { return mUiDevice; } /** * Get command line parameters. On the command line when passing <code>-e key value</code> pairs, the {@link Bundle} will have the key value pairs conveniently available to the * tests. */ public Bundle getParams() { return mParams; } /** * Provides support for running tests to report interim status * * @return */ public IAutomationSupport getAutomationSupport() { return mAutomationSupport; } /** * package private * * @param uiDevice */ void setUiDevice(UiDevice uiDevice) { mUiDevice = uiDevice; } /** * package private * * @param params */ void setParams(Bundle params) { mParams = params; } void setAutomationSupport(IAutomationSupport automationSupport) { mAutomationSupport = automationSupport; } /** * Calls {@link SystemClock#sleep(long)} to sleep * * @param ms * is in milliseconds. */ public void sleep(long ms) { SystemClock.sleep(ms); } protected void setDummyIme() throws RemoteException { IInputMethodManager im = IInputMethodManager.Stub.asInterface(ServiceManager.getService(Context.INPUT_METHOD_SERVICE)); List<InputMethodInfo> infos = im.getInputMethodList(); String id = null; for (InputMethodInfo info : infos) { if (DUMMY_IME_PACKAGE.equals(info.getComponent().getPackageName())) { id = info.getId(); } } if (id == null) { throw new RuntimeException(String.format("Required testing fixture missing: IME package (%s)", DUMMY_IME_PACKAGE)); } im.setInputMethod(null, id); } protected void restoreActiveIme() throws RemoteException { // TODO: figure out a way to restore active IME // Currently retrieving active IME requires querying secure settings provider, which is hard // to do without a Context; so the caveat here is that to make the post test device usable, // the active IME needs to be manually switched. } } ``` Following class is to test the calculator. But I dont knw how to use it.. Here's the link ``` package com.example.test; import com.android.uiautomator.core.UiObject; import com.android.uiautomator.core.UiObjectNotFoundException; import com.android.uiautomator.core.UiScrollable; import com.android.uiautomator.core.UiSelector; import com.android.uiautomator.testrunner.UiAutomatorTestCase; public class DemoCalTest extends UiAutomatorTestCase { public void testingCalculator() throws UiObjectNotFoundException { // First we testing the press of the HOME button. getUiDevice().pressHome(); // using the uiautomatorviewer tool we found that the button for the "applications" has //the value “Apps” (screen9) // so we use this property to create a UiSelector to find the button. UiObject Applications = new UiObject(new UiSelector().description("Apps")); // testing the click to bring up the All Apps screen. Applications.clickAndWaitForNewWindow(); // In the All Apps screen, the "Calculator" application is located in // the Apps tab. So, we create a UiSelector to find a tab with the text // label “Apps”. UiObject apps = new UiObject(new UiSelector().text("Apps")); // and then testing the click to this tab in order to enter the Apps tab. apps.click(); // All the applications are in a scrollable list // so first we need to get a reference to that list UiScrollable ListOfapplications = new UiScrollable(new UiSelector().scrollable(true)); // and then trying to find the application // with the name Calculator UiObject Calculator = ListOfapplications.getChildByText(new UiSelector().className(android.widget.TextView.class.getName()), "Calculator"); Calculator.clickAndWaitForNewWindow(); // now the Calculator app is open // so we can test the press of button "7" using the ID "com.android.calculator2:id/digit7" //we found by using uiautomatorviewer UiObject seven = new UiObject(new UiSelector().resourceId("com.android.calculator2:id/digit7")); seven.click(); // now we test the press of button "+" UiObject plus = new UiObject(new UiSelector().resourceId("com.android.calculator2:id/plus")); plus.click(); // and then the press of button "1" UiObject one = new UiObject(new UiSelector().resourceId("com.android.calculator2:id/digit1")); one.click(); // we test the press of button "=" UiObject result = new UiObject(new UiSelector().resourceId("com.android.calculator2:id/equal")); result.click(); //and finally we test the press of "Back" button getUiDevice().pressBack(); } } ``` I googled alot but could find any explanation about it. Can any one help me out. I am new to it Thanks
