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.javaviewplaincopyto clipboardprint?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

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 necessaryfor the first time running.)
# adb install./out/target/product/eagle/data/app/wifitoggletest.apk
# adb shell am instrument -wcom.example.wifitoggle.tests/android.test.InstrumentationTestRunner
