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;
    }

}

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);
            }
        }

}

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 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
