Mobile Applications Testing Peculiarities
Nowadays, the growing number of smartphones, tablets and other mobile devices accelerates the mobile applications development. Today, mobile applications have become not only a standard for communication for billions of users but also stimulate professional interactions and business around the world.
One of the application development elements is ensuring that the mobile application meets the customer expectations. Testing is represented as an important check of mobile developments which must be passed before the application is opened for the public.
Tasks for mobile applications testing
Testing of any application is aimed at improving the quality of the final product. The following aspects complicates the mobile applications testing:
Unlike desktop and web applications mobile applications are used on a large number of devices and platforms, such as iOS, Android, Windows Mobile, BlackBerry and others. There are also many versions of each operating system with various screen resolutions and memory sizes.
Mobile device fragmentation complicates the work because different operating systems have their own characteristics and the testing specialist must make sure the application works well on all the declared platforms equally.
Outsourcing and internal testing
Using an internal testing group, the company gets a full control over all actions, as well as its own testing team, which must be provided. In turn, outsourcing reduces time and costs for development companies and provides an access to the endless set of qualified professionals and testing tools.
Application lifecycle testing
Mobile applications testing methods require a constant updating due to the following factors:
- Users expect to fix bugs with almost real-time speed
- Regular updates of applications
- Flexible development methodology provides many benefits and additional updates
These aspects increase the need for mobile applications testing, as the testing cycle grows for each device, operating system and software.
Mobile applications testing strategy
Below you will find the key factors, that will help you choose a mobile application testing strategy, which will ensure quality assurance activities meet customer expectations, business objectives and best industry practices.
- Mobile device selection
The main task before the starting mobile application testing is to choose testing methods. When choosing a device, you must consider the following factors:
- OS version: test the mobile application on all the stable versions of the OS.
- Screen resolution: use a set of different screens for the testing by size and resolution.
- Form factor: if the application is compatible with smartphones and tablets, check it for form factors availability.
Also, when choosing a device model, you should take into account many other factors, such as memory size, connection parameters and so on.
- Emulators and physical devices
You can also choose between physical devices or emulators. Primarily, in the early stages of development, device emulators are extremely useful because they help to test quickly and efficiently, especially in a flexible development environment. Besides it, do not require costs.
The usage of mobile device emulators does not mean that you should avoid using physical devices in general. Testing on physical devices allows you to understand the actions of applications in real-world scenarios. Mobile applications testing is a using the right combination of emulators and physical devices to get the best results quickly and efficiently.
- Mobile applications cloud testing
Cloud testing of mobile applications allows you to manage potentially endless combinations of scenarios. Cloud testing is a desirable option for mobile applications testing.
Cloud computing provides a web-based mobile testing environment in which you can deploy, test and manage the application.
- Network connection
The adequate performance of most mobile applications depends on the network connection. Therefore, testing a mobile application in a real network environment is necessary to obtain a real picture of the application behavior.
There are many network modeling tools that you can use to test mobile applications based on network speed, bandwidth limitations, reducing the number of connections etc. A quality mobile application must provide a stable performance in various network environments.
- Manual and automated testing
Automation is a key to successful regression testing at development stages. However, automated testing requires significant initial investments. Therefore, automation of the testing should be carried out only in scenarios where:
- The application is developing
- The life cycle of mobile development is long
- The scale and frequency of regression testing are high
- A significant part of the test cases includes functionality test cases
In the case of manual testing, a group of testers should test various events that may occur while the application is running – incoming calls, SMS messages, low battery power, notifications from e-mail or roaming.
Manual testing is a necessary part of mobile applications testing because there are conditions that cannot be reproduced or prepared with the help of emulators. In addition, automated testing eliminates random and human errors.
- Mobile applications performance testing
It should be checked whether mobile application performance is getting worse by increasing the size of mailboxes, albums, messages, or any other content related to the application.
If the application has a user-created content or data associated with it (for example, photos, music, etc.), which can increase to huge sizes during the lifetime of the application, testing should include these scripts to see how the application works. If the application has a component on the server side, it is necessary to test the application with an increasing number of users.
- Mobile applications security testing
Users are worrying that their data is revealed due to vulnerabilities in applications. Here are a few questions to answer for successful mobile application security testing:
- Does the application store payment information or credit card information?
- Does the application use secure network protocols?
- Can they switch to insecure?
- Does the application ask for more permissions than it needs?
- Does the application use certificates?
- Does the application use the device ID as an identifier?
- Is the user authentication application required before data access is allowed?
- Is there a maximum number of login attempts before the application is blocked?
Applications must encrypt the user name and password when authenticating the user on the network. One of the methods to test security scenarios is to route your mobile phone’s data through a proxy server to find vulnerabilities.
We cannot ignore the importance of testing as a part of successful mobile application project. Despite this, a simple testing, without a strategy, does not guarantee quality and performance. Only by developing the right strategy you will go forward to the successful launch of the project.
A specialized testing company can help you to develop the right mobile testing strategy.
