使用Android Instrument 自动测试 WIFI_SERVICE
Porting 了新的Wifi hardware_legancy，
这个时候需要对对 Android Wifi On/Off 作压力测试
发现可以使用Android Instrument 和Android Test Project 来做测试。
1. 在Eclipse 里新建 一个 Android Test Project.
测试代码
AllTest.java
package com.example.wifitoggle; import junit.framework.Test; import junit.framework.TestSuite; public class AllTests { public static Test suite() { TestSuite suite = new TestSuite( "Test for com.android.settings.testsuite"); //$JUnit-BEGIN$ //$JUnit-END$ return suite; } }
WifiSettingTest.java
package com.example.wifitoggle.test; //import Forwarding; import junit.framework.Assert; import junit.framework.TestCase; import android.app.Activity; import android.content.Intent; import android.net.wifi.WifiManager; import android.util.Log; import android.os.Bundle; import android.content.Context; import android.test.AndroidTestCase; public class WifiSettingTest extends AndroidTestCase { private WifiManager mWifiManager = null; private final int TEST_COUNT = 10; private final int INTERVAL_DELAY_MS = 2000; protected void setUp() throws Exception { super.setUp(); Context serviceManager = getContext(); mWifiManager = (WifiManager) serviceManager.getSystemService(Context.WIFI_SERVICE); } private void sleep(int ms) { try { Thread.sleep(ms); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public void testTurnOnOff() { boolean enable = false; boolean result = false; for(int i = 0; i < TEST_COUNT; i++) { final int WAIT_TIMEOUT_S = 30; int wifiState = mWifiManager.getWifiState(); if(wifiState == WifiManager.WIFI_STATE_ENABLED) { result = false; Log.w("WIFI TEST", "Turning wifi off..."); mWifiManager.setWifiEnabled(false); for(int j = 0; j < WAIT_TIMEOUT_S; j ++) { sleep(1000); wifiState = mWifiManager.getWifiState(); if(wifiState == WifiManager.WIFI_STATE_DISABLED) { result = true; Log.w("WIFI TEST", "Turning wifi off success."); break; } else if (wifiState == WifiManager.WIFI_STATE_UNKNOWN) { Log.w("WIFI TEST", "Turning wifi off failed."); break; } } } else if (wifiState == WifiManager.WIFI_STATE_DISABLED) { result = false; Log.w("WIFI TEST", "Turning wifi on..."); mWifiManager.setWifiEnabled(true); for(int j = 0; j < WAIT_TIMEOUT_S; j ++) { sleep(1000); wifiState = mWifiManager.getWifiState(); if(wifiState == WifiManager.WIFI_STATE_ENABLED) { result = true; Log.w("WIFI TEST", "Turning wifi on success."); break; } else if (wifiState == WifiManager.WIFI_STATE_UNKNOWN) { Log.w("WIFI TEST", "Turning wifi on failed."); break; } } } Assert.assertTrue(result); sleep(INTERVAL_DELAY_MS); } } }
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.wifitoggle.tests" android:versionCode="1" android:versionName="1.0" android:sharedUserId="android.uid.system"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-library android:name="android.test.runner" /> </application> <instrumentation android:targetPackage="com.example.wifitoggle.tests" android:name="android.test.InstrumentationTestRunner" /> </manifest>
2. Eclipse 环境下的sdk版本 可能与实际 Android src 不兼容。 所以测试 WIFI SERVICE 这类framework 层代码，
需要将 测试程序放到Android 环境下编译，而不是在Eclipse 下编译。
实现这一步，只要简单的写一个Android.mk 然后将测试程序 目录拷贝到 packages/app/ 下， 再运行 mm 编译即可.
Android.mk
LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) # We only want this apk build for tests. LOCAL_MODULE_TAGS := tests # Also link against our own custom library. LOCAL_JAVA_LIBRARIES := android.test.runner #LOCAL_JAVA_LIBRARIES += com.android.settings # Include all test java files. LOCAL_SRC_FILES := $(call all-java-files-under, src) LOCAL_PACKAGE_NAME := wifitoggletest #LOCAL_INSTRUMENTATION_FOR := wifitoggle LOCAL_CERTIFICATE := platform include $(BUILD_PACKAGE)
# cd $ANDROID_PATH
# source ./build/envsetup.sh
# cd packages/app/WifiToggleTest
# mm
3.
wifitoggletest.apk 生成后就可以通过instrument 和 adb协议来测试 WIFI_SERVICE 功能了。
# croot
# adb uninstall com.example.wifitoggle.tests (It is not necessary for the first time running.)
# adb install ./out/target/product/eagle/data/app/wifitoggletest.apk
# adb shell am instrument -w com.example.wifitoggle.tests/android.test.InstrumentationTestRunner
