How to conduct performance testing on mobile applications? Please share the basic work flow

"With the technological advancement the demand for mobile applications is increasing by leaps and bounds and hence its market too. There are a lot many mobile applications available, capturing the market in accordance of their reliability and performance factor. So to satisfy the customers the performances of these applications should be unbeaten, that is why performance testing has become an indistinguishable part of the step to satisfy the customers. Performance testing can be done in many efficient ways one of them is to use the performance testing tool like eggplant.

Performance testing tool for the mobile applications like eggplant can time the individual events and sequences of events as well. This tool is can be used either to generate or to increase the existing small loads. There are other tools available in the market which create artificial load on the application on the other hand eggplant test the load by simulating the interactions of the real user. Eggplant is capable of validating and verifying the applications remotely across any platform

It is a black-box driven tool which does not make any interaction with underlying code. It includes many features which make it simple and powerful.

1. Image doctor: It can diagnose when the image changes and it continues script execution without any failure with matching the images. It provides the user with option to update the script automatically if a new image is found.

2. Connection List: With this feature it controls the connections by opening and closing them automatically during the script execution. There are a lot many other features like Results Pane, AHDB and Scheduler which are very helpful in making it a fast and easy to use tool."

As a whole world is going mobile today, performance testing is one of the most critical aspects for all mobile applications. Performance testing is basically testing of a system in terms of response time, stability under stressful situation. Performance testing of mobile is very important as mobile devices have some limitations in terms of utilization, memory usage etc. Mobile applications use protocol (HTTP, WAP, SOAP, etc.) to communicate to the server, using wireless devices. These calls get transferred through various network devices (e.g., routers, gateways of ISP) to connect the mobile application server. So we need to select performance tools which mimic the mobile application client traffic and record it from the mobile client or simulator. There are several tools available in the marketplace such as HP's Load Runner, Jmeter, Mobitest, IBM Rational Performance Tester, etc.

The performance testing of mobile applications is slightly different from the traditional performance testing due to its volatility. There are number of operating systems available on Mobiles such as – Windows, Android, iOS, Blackberry etc. And to test these devices selecting a right performance testing tool is very important; there are various open source tools available in the marked like Jmeter, Rubidium, etc. In Jmeter different devices can be various depending on the user agents. Also, before doing performance test on mobile application we have to ensure that the tool we are using has the ability to emulate in various network conditions (GPRS, EDGE, HSDPA, HSPA+ etc.) with quick and fast turnaround time. In today’s fast growing environment performance testing of mobile application plays very significant role, as an application is run on Mobile Phones of different parameters like memory, processor, screen size, resolutions and different network. Performance testing is initiated to determine system response and stability under a specific workload. Set of testing requirements may vary from application to application.

In order to test mobile application accurately it is necessary that following criteria must be included in our testing solution-
1.  Must support multiple devices
2. Must support native applications as well as web applications
3. Ability to record through the device as well as directly from a browser to reduce complexity
4. Ease of use and fast response time
5. Must have an ability to generate load from various locations, leveraging the cloud

Testing is performed until the application under test, results the desired levels of performance.

The Basic work flow:
Analyze the application → Test Plan and Test cases → Create environment → Simulate multiple Scenario → Execute → Result → Defect reporting → Test report

In Mobile testing services there are various challenges a QE face while testing a mobile App. Major challenge is that you can't actually test on all types of mobile devices to ensure that it will work on all supported mobiles. This will always be a major challenge for a QE. Another challenge is that mobile devices have different screen sizes, different types of input method and hardware’s. There are various types of mobile operating systems.

There are so many Challenges in Mobile App Testing. Some of them are:

1) Various Platforms or Operating Systems. Varity in different OS versions makes it a little bit difficult and challenging for testing mobile apps.

2) There are thousands of Handsets available in market with different Mobile App.

3) Regional Network Challenge. There are over 400 mobile network operators. Some of them are CDMA, some are GSM & some uses different networking norms. Each Network has a unique combination of network infrastructure which is used by mobile networks into TCP IP Protocol used by the mobile web.

4) Testing Mobile App into Real Environment becomes more challenging as this testing can be done only on target location.

What is mobile application testing? How do we verify that an application is ready for launch?

Nowadays the mobile world seems to have gone app wild. The huge diversity of devices makes it virtually impossible to sustain reasonable quality standards for their mobile applications and websites across platforms. People uses their smart phones for surfing the web, inter-platform compatibility is becoming imperative and carries serious business Implications. The complexity starts with the multitude of handsets having different screen sizes, hardware configurations and image rending capabilities. In addition, the proliferation of operating platforms (iphones, Android, Blackberry, Windows etc.) and the hundreds of carriers worldwide working on diverse local network standards (GSM, CDMA etc.) is putting further strain on development teams. For instance, the performance of a GPS application may be influenced by bandwidth limitations and loss of data. Similarly, an SMS feature that works in Canada will not necessarily work in France or Asia.
So testing is becoming more complicated, and mobile Testing is becoming increasingly expensive.

MOBILE TESTING

While doing Mobile App Testing, we come across with few challenges. What are those major challenges? As we all know that mobile industry keeps changing at a very fast past pace with new competitors entering into the market with latest mobile OS and dimensions .Today, Mobile world is totally dependent on the quality of applications it consists of. This is because a single risk in application can spoil the interest, entertainment and business of the users resulting in loss of faith towards the market leaders. It is important for a mobile application to be compatible with the platform like Android, Windows, Blackberry and many more. Apart from this, there is a major role of the type of Operator and its services so that there could be a performance test E.g. how frequently the application runs under different carrier technique like GPRS, EDGE, 3G or 4G. In addition there are some more factors need to keep while testing are screen size, keypad and sensitivity of full-touch. Hence it is important to test mobile applications under all circumstances so as to draw the interest of the users. The major challenges in Mobile App Testing due to wide range of handset makers, carriers, locations and operating systems are : a) Building a bug-free mobile app which is incredibly difficult and expensive. b) To ensure that the applications works properly for everyone, everywhere, all the time. c) Testing the common features as installation, login, and search etc. d) Need of security testing to save application from hackers. e) Multiplicity of mobile devices: Every mobile has different technical capabilities such as free memory space, screen resolution and orientation, network options, etc. f) Multiple Operating Systems: Today there are number of OSs available in the market such as Android, iOS, Symbian, Blackberry, etc. So, in order to test the mobile application we need to check the compatibility of the applications across all the mobile operating systems. g) Bandwidth: Due to lower bandwidth in the mobile connection application responds slowly which impacts the performance and functionality of the application. While doing the mobile application testing, we can introduce automation, what are those areas? There are various areas where we can use test automation during mobile application testing. We can use test automation when we need to convert test cases into the scripts i.e. write and record cases. We will later execute these test scripts onto the devices through automation. Best part is this is repeatable and reusable. In Mobile testing, automation is used to take care of look and feel like a native application for a specific phone models. In messaging function, we can also use automation technique, like T9 dictionary. Now touch apps are also used in mobile phone in which we can also use automation for touch apps. Automation can be used on call features like we speak any name on mobile speaker then application automatically searches for the respective user and gives the information of that user and also connect a call (if needed) or message to the same.
