Mobile-Apps-Performance

Mobile users of today are becoming more & more demanding, and they expect mobile apps to perform just as fast as their desktop software. Just take a look at the following insight:

  • 71% mobile phone users expect a website to open as quickly as their desktop PC.
  • Web app users turnaround starts just after 3 seconds of response time.
  • 50% app users and 74% website users leave if response time is 5 seconds or more.
  • 1/3 of the unsatisfied users go to a competitors site and never come back.

Performance Testing Tools for Mobile Apps

There are dozens of commercial and open source performance testing tools available for desktop browser based apps. But when it comes to mobile applications, the options are very limited especially for native mobile apps. There are a few open source tools for mobile web apps like JMeter, but not any for native mobile apps. Therefore, one has to turn to LoadRunner, Neo Load, Silk Performer etc. for native mobile apps performance testing.

Mobile Apps  Testing with LoadRunner

Mobile apps end to end performance testing is very challenging as it involves multiple devices and OS versions, app versions, and different servers for native and web applications etc. All these factors are not easy to address with a single tool. However, LoadRunner can tackle all the above mentioned challenges with minimal effort.

LoadRunner has different set of protocols for diversified applications. Following are the LoadRunner mobile protocols:

  • Mobile Applications – HTTP/HTML:

    This protocol records native and browser based mobile applications scripts (which use HTTP protocol for communicating with server) at transport level.

  • Mobile TruClient:     

    This protocol is based on Ajax TruClient technology and records browser based mobile applications only.

Following table summarizes which protocol can be used for which type of mobile application:

These protocols are OS-agnostic and work perfectly on different versions of iOS, Android, Windows Mobile and Blackberry etc.

Script Recording with Mobile Protocols

Ajax TruClient:

Script recording with Ajax TruClient protocol is very similar to standard web applications. Target mobile website should support Firefox and you can easily record user transactions on your preferred mobile device.

Mobile Application – HTTP/HTML:

You need to select a recording method first in this protocol.  Following is the summary of different recording methods available in Mobile Application – HTTP/HTML protocol for native mobile applications script recording.

  • Proxy Recording:                                                                                                              

    You can record mobile app script by configuring it to use VuGen Proxy, provided both are connected to same network and proxy configuration is allowed in application under test (AUT).

  • Server Side Recording:         

    This method is used when you don’t want to record with actual device. Mobile app script can be recorded by installing VuGen’s Mobile Sniffer Agent on AUT server, if that device, server and VuGen machines are on the same network.

  • Script from Network Capture:                  

    You can simply use the Analyze Traffic feature to develop script from network capture file.

  • Device Emulator Recording:                          

    You can record the Android application script through an emulator with Emulator Recording feature.

  • On Device Recording:

    You can also record mobile app script with a mobile device by installing LoadRunner Mobile Recorder on your device. Later, you can open recoded file on VuGen machine to create the script.

Once you have recorded the script, all subsequent steps are almost the same as you performed with a standard desktop web application.
