如何进行 iOS 稳定性测试

传统意义上的 monkey测试可以采用以下脚本：

function iOSMonkey2(){

this.elementArray = null;

this._addToArray = function(root,len){
var rootname = root.name()+""
rootname = rootname.toLowerCase();
if( !this._isIndicator(root) && root.toString() != "[object UIAKey]" && rootname.match("notap"+"$") !="notap" ){
if(root.isEnabled() && root.isVisible()){
if(len==0){
if(root.hitpoint() != null){
var rect = root.hitpoint();
if(rect.y>20){
this.elementArray.push(root);
}
}
}
if(this._toFlick(root) || this._toType(root)){
this.elementArray.push(root);
}
}
}
}

this._iterator = function(root){
var eleArray = null;
if(root.toString() !="[object UIAWebView]" && root.toString() != "[object UIAKeyboard]"){
eleArray = root.elements();
this._addToArray(root,eleArray.length);

if(eleArray.length != 0 && eleArray != null){
for(var i = 0; i< eleArray.length; i++){
this._iterator(eleArray[i]);
}
}
}
}

this._isIndicator = function(element){
return element.toString().match("Indicator"+"$")=="Indicator";
}

this._findIndicator = function(root){
var elements = root.elements();
if(elements.length !=0 && elements != null){
for(var i =0; i<elements.length;i++){
if(this._isIndicator(elements[i])){
return 1;
}
this._findIndicator(elements[i]);
}
}
}

this._getAllElements = function(){
var app = UIATarget.localTarget().frontMostApp();
this.elementArray = null;
this.elementArray = new Array();
this._iterator(app);
}

this._getElementAncestry = function(element){
var arr = element.ancestry();
var tmp = ""
for(var i = 0; i< arr.length; i++){
tmp += arr[i].toString()+"->"
}
return tmp;
}

this._selector = function(){
this._getAllElements();
var len = this.elementArray.length;
//UIALogger.logMessage(len+"");
var random = Math.round(Math.random() * len);
if (random == len){
random = random-1;
}
return this.elementArray[random];
}

this._toFlick = function(element){
if(element.toString()=="[object UIATableView]" || element.toString()=="[object UIAScrollView]" || element.toString()=="[object UIATableCell]"){
return 1;
}
return 0;
}

this._toType = function(element){
if(element.toString()=="[object UIATextField]" || element.toString()=="[object UIASecureTextField]" || element.toString()=="[object UIATextView]"){
return 1;
}
return 0;
}

this._tap = function(element){
if(element.toString()=="[object UIASwitch]"){
if(element.value() != "" && element.value() != null){
element.setValue(this._falseString(element.value()));
}
}else{
var x = Math.random().toFixed(2);
var y = Math.random().toFixed(2);
element.tapWithOptions({tapOffset:{x:x,y:y}});
}

}

this._flick = function(element){
//element.scrollToVisible();
var x = Math.random().toFixed(2);
var y = Math.random().toFixed(2);
element.flickInsideWithOptions({startOffset:{x:0.5, y:0.5}, endOffset:{x:x,y:y}});
}

this._getAppSize = function(){
var rect = UIATarget.localTarget().frontMostApp().rect();
return rect;
}

this._type = function(element){
var len = Math.round(Math.random()*100);
var value = this._randomChar(len);
element.setValue(value);
}

this._falseString = function(value){
if(value=="0"){
return "1";
}else{
return "0";
}
}

this._randomChar = function(len){
var  x="0123456789qwertyuioplkjhgfdsazxcvbnm";
var  tmp="";
for(var i = 0;i < len;i++){
tmp += x.charAt(Math.ceil(Math.random()*100000000)%x.length);
}
return  tmp;
}

this.operator = function(){
var element = this._selector();
UIALogger.logMessage("本次操作的对象的类型是："+element.toString());
var ancestry = this. _getElementAncestry(element);
UIALogger.logMessage(ancestry+element.toString()+"->name:"+element.name());
if (this._toFlick(element)){
this._flick(element);
}else if(this._toType(element)){
this._type(element);
}else{
if(element.hitpoint() != null){
this._tap(element);
}
}

}

this.screenShoot = function(imageName){
var target = UIATarget.localTarget();
var app = target.frontMostApp();
target.captureRectWithName(target.frontMostApp().rect(),imageName);
}

this.waitForLoad = function(preDelay) {
var target = UIATarget.localTarget();
if (!preDelay) {
target.delay(0);
}
else {
target.delay(preDelay);
}

var done = false;
var counter = 0;
while ((!done) && (counter < 60)) {
var progressIndicator = UIATarget.localTarget().frontMostApp().windows()[0].activityIndicators()[0];
var indicator = this._findIndicator(UIATarget.localTarget().frontMostApp());
if (indicator == 1) {
UIALogger.logMessage("来到这里等待一下")
target.delay(0.5);
counter++;
}
else {
done = true;
}
}
target.delay(0.5);
}

}

mon = new iOSMonkey2();
UIATarget.localTarget().setTimeout(0);
for(var i = 0; i< 1000; i++){
try{
mon.operator();
}catch(err){
UIALogger.logMessage("这里有一个异常");
UIALogger.logMessage(err.toString()+"");
}
mon.screenShoot("test");
mon.waitForLoad(1);
//UIATarget.localTarget().delay(2);
}

在 Instruments中直接运行，连接真机时，在 xcode》device中查看 crashlog。运行在模拟器时，在 控制台.app下查看 crashlogs.

另外，还需要考虑一些临界条件下的稳定性测试：

1）频繁收到内存警告时；

2）电池电量低；

3）3G网络不稳定时；
