android内存泄漏测试

要测内存泄漏呢，可以反复进入某一项操作，如反复进入联系人详情后返回键，观察内存的值是否有上升的趋势。

测试方法：

1.创建自动化测试脚本，每操作一次获取一次内存值，然后把内存值导出到文件中，制作成曲线图，就可以很直观的看见是否存在内存泄漏了。曾经用Uiautomator做过一次内存泄漏的脚本，如下：

package demotest;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Date;

import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiScrollable;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class MemoryLeak extends UiAutomatorTestCase {
// 应用包名
static final String packageName = "com.android.phone";

// 测试次数
static final int counts = 500;
public static void main(String[] args) {
String jarName, testClass, testName, androidId;
jarName = "demotest";
testClass = "demotest.MemoryLeak";
testName = "testScene_03";
androidId = "3";
new UiAutomatorHelper(jarName, testClass, testName, androidId);

}

// 场景一：打开/退出联系人

public void testScene_01() throws IOException {
File mTxt = mkFile("01");// 创建文件
FileOutputStream fos = null;// 以字节流的形式读取
fos = new FileOutputStream(mTxt);
for (int i = 0; i < counts; i++) {
scene_01();// 执行场景一的case
sleep(2000);// 延迟2s
String mMemory = memory(packageName);// 读取每一次的memory
sleep(2000);
byte[] b1 = (mMemory + "\n").getBytes();
fos.write(b1);
}
fos.close();
}

//场景二：查看联系人

// 读取每一次的内存值
public String memory(String packageName) {

proc.waitFor();
BufferedReader br = new BufferedReader(new InputStreamReader(
proc.getInputStream()));
while ((line = br.readLine()) != null) {
if (line.contains("TOTAL")) {
sb.append(line + "\n");
}
}
String[] s = sb.toString().split("TOTAL");
String s2 = s[1].trim();
String[] s3 = s2.split("    ");
Pss = s3[0].trim();
System.out.println("***调试开始***");
System.out.println(sb.toString());// 打印字符串
System.out.println(Arrays.toString(s));// 打印数组
System.out.println(s2);
System.out.println(Arrays.toString(s3));
System.out.println("Pss=" + Pss);

return Pss;
}

// 格式化时间
public String formatDate() {
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHms");
String time = sdf.format(date);
return time;
}

// 创建文件保存日志
public File mkFile(String casename) {
String path = "/storage/sdcard0/uiautomator/memory";
String file = path + "/Scene_"+casename + formatDate() + ".log";
File filePath = new File(path);
File txt = new File(file);
if (!filePath.exists() && !txt.exists()) {
filePath.mkdirs();
try {
txt.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
return txt;
}

}

2.用 bat脚本连续读取应用程序的内存使用情况（一边操作一边观察内存值是否一直上升）

set process=com.android.contacts
@adb shell dumpsys meminfo %process% | findstr "Pss"
:m
@adb shell dumpsys meminfo %process% | findstr "TOTAL"
@ping -n 5 127.1>nul
@goto m

3.用eclipse中的DDMS

手动连电脑，选中要测试的进程名--点击Update help--操作应用的同时观察右边Heap区域的total size是否会一直上升，在此期间可以点击GC按扭触发android垃圾回收

如果一直呈上升趋势则点击Dump HPROF按扭把内存映像拷贝下来，然后用MAT工具去分析。



上面这命令也可以获取HPROF文件
