With smartphones gradually becoming a must-have, developers are finding good careers in mobile app development. The markets are eventually getting flooded with millions of apps. But the truth is only a few are able to make their mark and rule the mobile world.
In such high competency ratio, you have to be sure that apart from offering something innovative and interesting to your customers your application should also be free from any glitches. And hence, mobile app testing is becoming very important.
Mobile application testing is a procedure to test mobile applications for usability, functional, and consistency glitches.
The type of mobile app you are testing plays a very important role in defining your testing process. So, be very clear about which type of mobile app you are going to test. They are largely categorized into three different types:
Strategizing your testing efforts can help you carry out testing in a streamlined manner thus increasing its efficiency and effectiveness.
The basic points that you need to consider while strategizing your mobile app testing efforts are:
Testing on a real device is always the best decision for your mobile app testing. It gives the highest accuracy. But, with markets flooded with hundreds of various brands and various models of mobiles, selecting the most appropriate one for your testing is a cumbersome task.
Here are some pointers that can help you with the selection of the devices:
Emulators or simulators are widely used for mobile testing these days. But what are these Emulators or simulators? They are tools that are capable of emulating/simulating the behavior and working of mobile devices.
Though many of us might confuse between “Emulator” and “simulator and might mistake them to consider the same. But they are very different.
An emulator is the original device replacement that allows you to run applications on your gadget without being able to modify them.
While simulator doesn’t imitate mobile’s hardware but can set up the analogous environment as of your original mobile’s OS.
Hence Simulators are preferred to test mobile application whereas Emulators are better for the mobile web application testing.
Allowing run mobile devices to run on several systems and networks, cloud-based testing helps to get over the drawbacks of simulators and real devices.
Some testers till date support manual testing while to others they believe it is going to die. But the fact is that both automation testing and manual testing are important.
There are scenarios that are best tested with automation testing, but there are few that give the finest results with manual testing.
Let us now learn about various stages of the mobile application. Here goes the list:
The beginning of mobile testing takes place from Documentation testing -preparatory stage.
Even before the development of the app starts the testers are handed over screen layouts, navigational charts, and other requirements that are obscure on the design.
In this phase, you need to analyze the requirements for wholeness and discrepancy. All the discrepancies found in this stage are required to be resolved before the development begins
Documentation phase marks the creations and analysis of requirements (Specification, PRD), Test Cases, Test Plan, Traceability Matrix.
It helps you test whether your mobile application works as expected and in accordance to the requirement specifications. While you are performing functional testing for your app keeps the following factors in mind:
The basic validations that you need to test in functional testing are:
Usability testing ensures that your application offers convenient browsing to your customers and creates an intuitive interface that abides by industry standards. It promises fast and easy-to-use applications. Usability of your application is judged based on these basic three criteria:
User Interface (UI) testing ensures that your application’s GUI meets all the required specifications.
Compatibility (Configuration) testing validates the optimal performance of your application on different devices based on their size, screen resolution, version, hardware, etc. Compatibility testing also takes care of
Compatibility testing can be further divided into
Cross-platform testing: Testing your mobile application compatibility with different operating systems: Windows, iOS, Android, and BlackBerry, etc.
Cross-browser testing: Testing your mobile application compatibility in different browsers Google Chrome, Mozilla Firefox, Opera Mini, etc.
Database testing: Testing your mobile application compatibility in different database configurations: DB2, Oracle, MSSQL Server, MySql, Sybase.
Device Configuration testing: Testing your mobile application compatibility on different devices based on
Network configuration testing: Testing your mobile application compatibility in different network configurations (TDMA, GSM) and standards (2G, 3G, 4G).
Performance testing helps you test your application reaction and constancy under the specific workload.
Performance testing attributes
Security testing validates the security features of your application. It also analyzes the risks of application hackers, protection, viruses, and unauthorized access to extremely sensitive data.
Recovery testing tests the ability of your application to withstand and successfully recover from possible and potential failures caused by software issues, hardware failures, or communication problems.
Localization testing tests the adaptability of your application for a specific target audience based on cultural specifics.
Finally, when complete testing is done, you might find some bugs, resulting in a certain piece of code to change to eliminate those bugs. After these code changes you again need to carry out a round of testing. This basically includes:
11. Beta testing
Beta testing is done by real users on real devices to validate usability, functionality, compatibility, and reliability testing.
Before pushing your app forward for beta testing, take account of the following factors
Beta testing is good investment ensuring a better quality of your mobile app.
Let’s systematize our knowledge, and try to determine the main tips for mobile application testing.
For functionality testing: Appium, Selendroid, Robotium, Ranorex.
For usability testing: Reflector, User Zoom, Loop.
For mobile application interface testing: iMacros, FitNesse, Jubula, Coded UI, LoadUI.
For compatibility testing: CrossBrowserTesting, BrowserStack, Browsera, Litmus, Rational ClearCase, Ghostlab.
For performance testing: Apteligent, NeoLoad , New Relic.
For Security Testing: OWASP Zed Attack Proxy, Retina CS Community, Google Nogotofail, Veracode, and SQL Map.
