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 android.content.Intent;
import android.net.wifi.WifiManager;

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();

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);
}
}

}

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)

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 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
