In our day to day, life mobile has become very important part and it seems that we are not able to move without mobile. In addition to calling and sending SMS, mobile nowadays is providing a wide variety of other services like instant chatting, Sending MMS, Sending emailFirst, Internet access and short range wireless communication (Bluetooth) hence need of Mobile Application Testing.

First of all, it is important to know clearly what Mobile Application Testing is. It should be clear in mind that Mobile Application Testing has nothing to do with the testing of Mobile devices whether Mobile Device is working properly or not.

For example, whether a mobile device is shutting abruptly or hanging or anything related to mobile device working. Rather it is testing of the application installed on mobile device.

Types of Mobile Applications

Native Application

Applications are which are installed through Play store on Android or App Store of Apple or directly from mobile browsers. Native apps are those apps which are downloaded from the marketplace and installed on your mobile device.

Once downloaded, they are updated by a company of which the application belongs to, as they release some patches or updates to enhance and optimize the application. Native apps are different for different for the different configuration. Same applications which are developed for Apple IOS, are different from the application that is developed in Android OS.

There is difference in the way they are developed and configured in different environments but in the end, behaves in the same manner

Things to Test in Native Application

  • The testing Native mobile application starts from download and installation. It is checked whether download and installations are up to the mark or is there any issue while doing so.
  • Next thing to check is its execution in different networks, different field scenarios like congestion or less signal, different battery conditions, or different screen orientations.  Working on the app is tested on different networks like 2G, 3G, and 4G or Wi-Fi.
  • Different screen orientations are checked whether a screen is aligned horizontally or vertically as per device movement. Also checked is, what the effect on an application is when battery suddenly goes down or check the result when a download of the application stops in between.
  • Mobile Application Testing is done with different change made in the device settings, so as to find out any negative impact of device settings on application.
  • Mobile Application Testing is done with different auto-update setting.
  • Mobile Application Testing is done on the different device with different versions and different operating systems. The application may have different Operating systems or versions. Apple IOS, Blackberry OS, and Android OS are some of different OS.

Web app

Another type of application for which Mobile testing is required is called as a Web app. Testing is done on browsers like chrome or Firefox or Android browser installed on your mobile device. It is common in all browsers. Only screen size or resolution is different. What we test mainly in a web app is that whether the page of web app loading properly and functionality u. Another testing to be done is same as what is done for the native app.

Similarity and Difference between Mobile Application Testing and Web testing

  • As far as functionality testing is concerned, Mobile Application Testing is quite similar to testing web application. Testing is done based on Test Plan.  
  • It is checked how the network behaves on Wi-Fi, dongle and different types of network or what happens when the network is busy or having high load? What happens when it is being installed? This is what differentiates between we application testing.


Types of Mobile Devices

  • Real Devices: Actual testing is done on it. It is expensive as it is associated with device cost. The disadvantage of doing browser testing is that there is a large number of device and browsers and their versions. Also, testing required to be done on two or three Operating Systems. So, to do Mobile Application Testing on all these devices, it is required to procure them which is a very costly affair. Also, it is quite important to do testing on real devices, as these gives exact information of how the end user is going to use the application.
  • Emulated Device: These devices try to simulate the real device. It is easy to capture and report errors. Though it does not give realistic information but the level of simulation is quite high.

Best practices that are followed while doing Mobile Application Testing

  • First of all, we should test the mobile application on the simulated device, because it is easier to load on the system to perform smoke testing, so as to send it for detailed testing on real devices.
  • Before doing Mobile Application Testing on the real device, it is quite important to have Test Plan. Test Plan should contain features to be tested or Test scenarios, environment information like OS, Devices, Versions, Browsers, and Types of Testing that is manual or automation.
  • Checklist needs to be prepared for different environments.There may be some test scenario like what happens when using the application when the battery is 15% or what happens when the movie is being played in the background or another app is running in the background. The checklist helps us in preparing out the report about what are the findings when running test scenarios on different environments or what we may call environment consisting of different OS, devices, browsers and their versions. Also, minimizes chances of leaving any test to go unexecuted on any platform.
  • Mobile Application Testing needs to be done in a different field environment. For example in the crowd with lots of network traffic or testing through remote control or testing during driving or testing when the network signal is not there. Mobile testing is sometimes done through Remote connection where machine containing application is at some other location.
  • Mobile Application Testing is done with different setting on the mobile device. Some of the examples are changing the brightness, keeping Wi-Fi on and off or keeping it in Airplane mode or different settings on keyboard or change in languages.
  • Automation plan should be in place for testing the same functionality again and again as it is possible that same functionality is there in the new version, so as to save time and effort.


Overall, we can say that Mobile Application Testing has become very important nowadays. It is quite easier to operate the application on mobile rather than opening your computer and running it. People are moving to mobile for accessing desired applications.

Also, networks were slow earlier. 2G was slow. But now with coming of 3G and 4G, people are finding it easy to work on the mobile application. Also, lots of application with enhanced features is available which has increased its usage on the mobile device. Everything nowadays is going mobile.

However, as mobile application marketing is growing very fast, mobile application testing has also become very challenging due to variation in handsets, phone carriers, networks supported and an application written in different languages. Different types of mobile platforms, operating system and mobile screens with different sizes adding more challenges to it.
