Why Automated Performance Testing?

If you can’t mea-sure it,

you can’t manage it. Peter F. Drucker

If you can’t automate the measurement of it,

it is difficult to im-prove it.

Instrumentation

Android instrumentation is a set of control methods or "hooks" in the Android system. These hooks control an Android compo-nent independently of its normal lifecycle.They also control how Android loads ap-plications.

How to Use kmemtracer?

1. Create an Android Test Project for the trace package.

1. Create an Android Test Project for the trace package.2. Add ‘kmemtracer-libs.jar’ in the ‘libs’ directory.

1. Create an Android Test Project for the trace package.2. Add ‘kmemtracer-libs.jar’ in the ‘libs’ directory.3. Edit the <instrumentation> element in the Manifest file.

4. Install the trace package as well as the applica-tion package.

$ adb install –r ApiDemos.apk$ adb install –r ApiDemosTest.apk

5. Start the instrumentation with ‘am instrument’ in the shell.

$ adb shell am instrument -e class \> com.example.android.apis.ApiDemos \> com.example.android.apis.tests/\ > org.kandroid.memtracer.MemoryInstrumentation

6. Do interact with the application.

Controlling UI Using Instrumentation

1. Create an Android Test Project for the test package.

$ android create test-project --main ../ApiDemos \> –-name ApiDemosInstrumentTest --path ApiDemosInstrumentTest

2. Add a test class inheriting ActivityInstrumen-tationTestCase2.

public class ApiDemosInstrumentTest extends ActivityInstrumentationTestCase2<ApiDemos> { ... public ApiDemosInstrumentTest() { super(ApiDemos.class); }

2. Add a test class inheriting ActivityInstrumen-tationTestCase2.

3. Add a test method and launch the activity.

public class ApiDemosInstrumentTest extends ActivityInstrumentationTestCase2<ApiDemos> { ... public ApiDemosInstrumentTest() { super(ApiDemos.class); }

public void testNavigate() { final ApiDemos apiDemos = getActivity(); ... }

public void testNavigate() {

4. Find and act on a control.

public void testNavigate() { ... final ListView demoList = apiDemos.getListView(); final View graphicsDemo = getChildViewByText(demoList, "Graph-

ics"); assertNotNull("Graphics demo should exist", graphicsDemo);

Find a view

to con-trol

apiDemos.runOnUiThread(new Runnable() { public void run() { int pos = demoList.getPositionForView(graphicsDemo); demoList.smoothScrollToPosition(pos); demoList.setSelection(pos); demoList.performItemClick(graphicsDemo, pos, graphicsDemo.getId()); } }); ...

Find a view

to con-trol

Act onthe view

apiDemos.runOnUiThread(new Runnable() { public void run() { int pos = demoList.getPositionForView(graphicsDemo); demoList.smoothScrollToPosition(pos); demoList.setSelection(pos); demoList.performItemClick(graphicsDemo, pos, graphicsDemo.getId()); } }); ...

Find a view

to con-trol

Act onthe view

private View getChildViewByText(ListView listView, String text) {

4. Find and act on a control: getChildViewByText.

4. Find and act on a control: Revised getChild-ViewByText.

5. Monitor a new Activity to launch.

public void testNavigate() { ... Instrumentation.ActivityMonitor graphicsDemoActivityMonitor = getInstrumentation().addMonitor( ApiDemos.class.getName(), null, false); final ApiDemos graphicsDemoActivity = (ApiDemos) graphicsDemoActivityMonitor.waitForActivity(); assertNotNull("Graphics Demo (ApiDemos) activity should not be null", graphicsDemoActivity); ...

5. Monitor a new Activity to launch.

6. Iterate step 4 & 5.

public void testNavigate() { ... Instrumentation.ActivityMonitor graphicsDemoActivityMonitor = getInstrumentation().addMonitor( ApiDemos.class.getName(), null, false); final ApiDemos graphicsDemoActivity = (ApiDemos) graphicsDemoActivityMonitor.waitForActivity(); assertNotNull("Graphics Demo (ApiDemos) activity should not be null", graphicsDemoActivity); ...
