Common Issues While Creating Performance Scripts

Common Issues While Creating Performance Scripts

When you start load testing a web site (especially if this is the first load test in your life) you may see a lot of errors in the report. Possibly you will even have to stop the test before it completes, because at some point in time it becomes clear that something goes wrong. If the problem is not so obvious, it is still recommended to check the report for the errors related to each virtual user profile (i.e. to each different type of virtual users) before looking at any performance data.
Issue 1:  
Most probably the errors appear because you have not parameterized the HTTP requests in your profile. Note that initially all requests are recorded as is. If user use a recorded profile without any modifications. Performance tool will simply repeat all the same requests with the same values of all parameters. However some values should be unique for each session.
You can check the “Logs” folder for errors and find the first request that produced an error. The goal is to find dynamic session-specific values inside that request. You can do this by comparing different sessions. Usually such session-specific values are contained inside the request parameters, but they can also be passed inside the main part of the URL. When you find such value you also need to find a place (the body of one of the previous responses) from which you can extract it. You can use the “Edit | Find and Replace…” feature for that.
Issue 2:  
Let’s imagine that you have done good work on the parameterization and now when you verify your profile, it does not produce any errors, and each new session completes as expected. Now you try to execute a small test with several concurrent users, and you see that it fails for all users except the first one. The problem may be that your web site does not allow several concurrent sessions with the same user credentials. This means that you need to use a different user name and password for each virtual user.
After you make all necessary modifications to the profile you can enable the full logging to check that all user names and passwords are passed correctly. By default logging is enabled only for verification, but if you run test with just few users, you can switch to full logging without any significant performance overhead.
Issue 3:  
Even in case the user credentials are passed correctly, you may still see that almost all sessions complete with errors. This may be because some session-specific values still require parameterization, because they depend on the user account. Basically this is the same problem as the first one. I only wanted to note that you may face it again when you switch from one user to many users test.
For example, it may be that each user of your system has a special ID which is passed in some parameter of each request. If you use a different user name, you also need to change that ID. As usual the right value can be extracted from some response and assigned to a variable.
Issue 4:  
Your web application may require authentication. This is not exactly the same as entering the user name and password in some form on a web page and clicking the “Sign In” button. When you use a browser to access a site requiring authentication, it displays a separate dialog asking for credentials. Since this is done in a secure manner, it is not possible to record the credentials automatically
Issue 5:  
There is one very important rule that you should apply when creating a new virtual user profile: always start recording by entering the landing page URL into the address bar and always delete cookies and browser cache before recording. This is not just a good advice; this is the only correct practice.
If you start recording from the middle of a user session, your load testing tool will not be able to reproduce that session correctly. Even if you click a link on a page already open in your browser instead of manually entering the address, this can produce incorrect recording.
The same will happen if you do not delete cookies. Your web site may behave differently for new users and for returning ones. It may use cookies to restore the previous session. If you record such restored session, you will not be able to emulate a new one.
Finally, if you do not delete browser cache, all requests to cached elements will be skipped on recording. This is the least important problem, because any session-specific requests will be sent in any case, but to create a realistic load you will probably want to load page elements as well.
Important Note:
If you see errors in the report, you should definitely research the problem as described above. However even if you do not see any red lines in the log, this does not mean that everything works correctly. Your web site can produce errors in a “user friendly” manner or just redirect to a different page if it cannot provide valid content for a request containing incorrect parameters. This means that you need to read the actual response to see if it is correct. Again, you can use the “Compare with recorded” function and check all responses step by step.

How to use ADB (Android Debug Bridge) over WiFi | Android automation

Whenever we work with Android mobile app automation we have to connect the device using USB cable. We can connect the device over Wi-Fi. To get rid of from the USB there is a super simple way! All you need is a USB cable (for the initial setup) and have both devices in the same network. This will work for non-rooted devices also.

Precondition: 
  • Your system and device must be in the same network.
  • Android mobile must have developer option set to true.
  • ADB (Android debug bridge) must be configure
  • Android SDK installed.
Step 1. Attach mobile via USB

Step 2. Open then command terminal type adb devices and press enter

It will confirm that your device is connected and able to recognize by android sdk.




Step 3:   type:
adb tcpip 5555
Step 4:To find the mobile ip type:
adb shell ip -f inet addr show wlan0
Step 5: The ip address will be shown in second line like this:
inet 192.168.1.233/24 brd 192.168.1.255 scope global wlan0
where 192.168.1.233 is the ip address of your mobile.
Step 6:Remove USB cable and type:
   adb connect <mobile-ip>:5555

 like:
adb connect <192.168.1.233>:5555 

Note: 
  1. Make sure: that you do not have Android studio running before executing the - 'restart adb in tcpip mode' command
  2. If you have IDE running then adb may have been already started and you may need to restart it in some cases: adb kill-server; adb start-server

How to know app package and activities information without having apk | android app | Appium

How to know app package and activities information without having apk | android app | Appium

In Android app mobile automation,we need apk file of app but sometimes we have to perform action on inbuild app(pre installed) which come with device like call,sms etc.. for this we do not have apk file. Basically in android app automation we need app package information  and app activities. In case of apk it is easy to get above information with appium. But if we do not have apk and need the app package/activities information, we can use following command:

Precondition: 
1. Android mobile must have developer option set to true.
2. ADB (Android debug bridge) must be configure
3. Android SDK installed.

Step1. Open then command terminal type adb devices and press enter

It will confirm that your device is connected and able to recognize by android sdk.






Step2: Now in mobile, open the app of which you want to get app pkg info/activities. In your mobile, it should be current activated app with focus. Means current window of your mobile should be app like calling/msg/your app window. 

Step3: Now type adb shell and press enter to open the adb shell

Step4: type dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'  and press enter







Above command will show the current activated app info of  your mobile. Now check the value of mCurrentFocus.

First highlighted text is pkg info



Second highlighted text is app activities info


Here you can see that we can use this:

WebDriver compare data/css between two pages

Hi All,

In Web based project like implemented in CQ5 where we have to check same site for different country. For this we have to rollout/replicate some/all pages for different countries OR I can say downloaded/uploaded the production data in testing environment or vice versa.
After this we have to validate page static data (like text) with production site Data, page wise validation.
E.g.  One page of US site and replicate the same page for another country then verify page content or css
For this we have to check manually, we can automate the same. I assume both pages having same text content (English).
Logic to implement this:
First we have to analyze page objects properties (what are the common page objects (elements) properties are being used) like class, id, type etc and create array of this.
Then we have to get all elements from the base page(expected) using xpath(//*)
For each element get all properties and value using java script and store only those element properties/value which are matching with common page objects (elements) properties stored in array.
Create locators for those elements by generating xpath for them.
Now same locator(xpath) should be exist in actual page
open two driver instances driver1 for page1 , driver2 for another country page2
Using WebDriver find element by xpath(locator) from base page and same for another page, match the text using gettext() method if  same element present in both pages
We can use same for CSS attribute values check for two pages having same element with same type of properties(class, ID etc)

Here is the code to implement this.


public static List<String> getPageLocatorsxPath(WebDriver driverbase,String pageURL )
{
List<String> strLocatorxPath = new ArrayList<>();
/// Common attributes from base site pages
String[] attributes = { "class", "data-class", "data-class-name",
"data-tab", "id", "name", "data-countrycode" };

HashMap<String, String> mapWeblementAttributes = new HashMap<String, String>();

JavascriptExecutor js = (JavascriptExecutor) driverbase;

/// get all elements from page
List<WebElement> childElementsGSAM = driverbase.findElements(By
.xpath("//body//*"));
int counter=0;
for (WebElement webElement : childElementsGSAM) {

// check only those element which are visible and displayed
if (webElement.isDisplayed() & webElement.isEnabled()) {

mapWeblementAttributes.clear();
// get element tag name use for creating Xpath
String strTagName = webElement.getTagName();
String strAttributes = (String) js
.executeScript(
"var str = '', obj = arguments[0].attributes; for (var key in obj){if(obj.hasOwnProperty(key)){str = str + '~' + obj[key].name + '=' + obj[key].value;}}; return str;",
webElement);
// store element properties and value in map
String[] arrAttValues = strAttributes.split("~");

for (String attribute : attributes) {
for (int k = 0; k < arrAttValues.length; k++) {
String[] arrAttrValue = arrAttValues[k].split("=");
if (arrAttrValue.length == 2) {
String strAttr = arrAttValues[k].split("=")[0];
String strAttrValue = arrAttValues[k].split("=")[1];

// store only if element property match with defined properties
if (attribute.equals(strAttr)) {
mapWeblementAttributes.put(strAttr,
strAttrValue);

}
}
}
}
// create element locators only if attribute size >1 like class and id etc..

if (mapWeblementAttributes.size() > 1) {
Set<String> setUIKeys = mapWeblementAttributes.keySet();
String strLocatorStart = "//" + strTagName + "[";

bAnd = true;
}
String finalxpath = strLocatorStart +strLocator + "]";
System.out.println(finalxpath);
strLocatorxPath.add(finalxpath);
counter++;
} else {
System.out.println("not able to create locator for "

}

Difference between action.build().perform() and action.perform()


In Webdriver, handling keyboard events and mouse events (including actions such as Drag and Drop or clicking multiple elements With Control key) are done using the advanced user interactions API . It contains Actions and Action classes which are needed when performing these events. In order to perform action events, we need to use org.openqa.selenium.interactions.Actions class.

The build() method is used compile all the listed actions into a single step.
we have to use build() when we are performing sequence of operations and no need to use only if we are performing single action.

example where build() required
Actions builder = new Actions(driver);
builder.clickAndHold((WebElement)listItems.get(0)).clickAndHold((WebElement)listItems.get(3)).click().build().perform();


in the above code we are performing more than one operations so we have to use build() to compile all the actions into a single step

example where build is not required

WebElement draggable = driver.findElement(By.id("draggable")); 
WebElement droppable = driver.findElement(By.id("droppable")); 
new Actions(driver).dragAndDrop(draggable, droppable).perform();
in the above code we are performing just a single operations so no need to use build()

Scrolling web page with Webdriver using java

We can scroll the web page using javaScript Executor or You can use the "org.openqa.selenium.interactions.Actions" class to move to an element:


Following classes you required in you java code
import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement;
import org.openqa.selenium.Alert; import org.openqa.selenium.By; import org.openqa.selenium.JavascriptExecutor;

1. We may require to scroll to bottom of the page and then perform operations. For this scenario we can use following code
((JavascriptExecutor) driver).executeScript("window.scrollTo(0, document.body.scrollHeight)");

2. Some times, we may require to scroll to particular element and peform operations on that particular element. For this we need to pass the element on which we need to perform operation. For this scenario we ca use following code
WebElement element = driver.findElement(By.linkText("googleMap")); ((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView();", element);
OR
WebElement element = driver.findElement(By.id("my-id"));
Actions actions = new Actions(driver);
actions.moveToElement(element);
actions.perform();

3. We can also use the coordinates to scroll to particular position by passing the coordinates. For this scenario we use following code
((JavascriptExecutor) driver).executeScript("window.scrollBy(0,500)");

How to Re-Sign an iOS App from an External Developer/



iReSign allows iDevice app bundles (.ipa) files to be signed or resigned with a digital certificate from Apple for distribution. This tool is aimed at enterprises users, for enterprise deployment, when the person signing the app is different than the person(s) developing it.


If you ever work with 3rd party developers, you know that getting the final project into production can take two different routes. You can either let the developer push the code/project into production or they hand it over to your internal team to release. There are pros and cons for each, but I always prefer to publish things ourselves since it reduces security concerns and gives us more control. The Apple App Store is no different, and it is actually really simple to take a developer app and turn it into an App Store version for submission.

Note: You can use this exact same process to resign the app to your developer certificate and profile, so you can install it on your own registered developer devices.

Step 1: Pull the latest iResign code from Github “$ git clone https://github.com/maciekish/iReSign.git

Step 2: Build the code from Xcode

Step 3: In the window that appears “Enter the path to valid provisioning profile”, “Leave the fields to .plist file blank” and “Enter the build identifier from application”

Step 4: From the drop-down "Select valid developer profile” and click on "ReSign!” button.



Note: Resigned file will be saved to same directory as of original application.

Advantage:


  • We now have to ask from client just .ipa file for automating on iOS platform, same as we require just .apk file for automating on android platform
