Types Of Mobile Testing
Here are the different types of mobile application tests that are required to perform before releasing the product to the end user.
Installation Testing
Installation testing checks the procedures for installing a software system and ensures that the system functions appropriately once installed. The installation process is an important first impression, so the app should be easy to install and free of glitches. If the app takes longer than expected to install or if there are installation issues, the customer will likely seek out an alternative.
Thus, it is crucial to have installation testing as one of the mobile app testing processes before every version release. The key test scenarios that should be covered in installation testing of the mobile apps are:
You can switch between other apps while the mobile app is installed.
Disable your device’s internet connection or switch to flight mode.
Switch between cellular data and WIFI connections.
Regardless of the storage choice (local storage or memory card), the app’s installation process should succeed.
Check the storage when the available space runs low.
Functional Testing
Functional testing of mobile apps is designed to ensure that every functional aspect of an app works according to the defined business requirements. It is usually performed by individuals involved in testing mobile apps. Users will uninstall an app if it does not function as intended. Functional testing is, therefore, a critical type of software testing.
Usability Testing
Usability testing is crucial for any mobile app because it ensures that it meets the criteria for ease of use and user experience. For example, providing an intuitive app design in the form of layout, buttons, navigation options, and color choices can impact user experience.
Usability testing is one of the challenges in mobile application testing that must be carried out before release. It involves refining the app based on user feedback and normal usage patterns. Thus, it is best to involve real users during usability testing to ensure that the app passes this test.
Compatibility Testing
Compatibility testing is a form of non-functional mobile app testing that ensures a mobile app’s functionality across various operating systems, applications, devices, internal hardware specifications, and network conditions.
Before launching an app, compatibility testing is performed to ensure good operability across different devices, operating systems, and browser versions. Software development teams work toward a bug-free, user-friendly mobile application that follows industry-standard software guidelines.
Localization Testing
To ensure that its app meets customers’ needs around the globe, a company should localize it for different regions. Localization testing is key to ensuring that an app can be used in a variety of languages and contains accurate currency conversions, and adheres to local legislative standards.
Localization testing ensures that software behaves as expected, is accurate, and can be localized for different cities or countries. It can range from testing a program’s behavior in a single city to simulating how it will respond throughout an entire country.
Interrupt Testing
Interruption testing is one of the mobile app testing types that should be performed. In reality, people switch between apps for various reasons, such as making a call, sending a message, receiving notifications in an ad-hoc manner, etc. All these interruptions shouldn’t negatively impact the mobile app’s performance or functional aspects; this is where interruption testing comes into play.
Automating the interruption test scenarios such as manually switching between the apps, remaining in other apps for some time, and then switching back to the mobile app under testing, finding, and sharing the current location (As it involves the usage of a sensor), making a call, sending messages, pressing the lock button or volume up/down button, etc. would increase the productivity of the development and testing process.
Memory Leak Testing
When a program fails to return the memory it has acquired for temporary usage, it causes a memory leak. This can cause an app’s available memory to run out, causing the app to become unusable. Because code errors cause memory leaks, every app should be checked for this problem.
Memory leak testing is a process that can be performed on an app running on multiple devices with varying memory capacities. Testers examine each device’s performance and tune the program to work well in each configuration.
Performance Testing
Mobile app users have high expectations of how quickly an app should respond to their actions. The speed of an app’s response depends on its code, the device’s hardware, and the OS. Users may become frustrated and uninstall if an app does not respond in 2 to 3 seconds.
Developers and testers must perform performance tests to discover bottlenecks in your mobile app. Key aspects of a mobile app performance test strategy include the following:
The response time of the app to each event triggered by the user.
Time to render the user interface.
How network conditions impact the response of your app and its other characteristics.
The present battery charge level and the app’s response behavior are impacted by battery usage.
Security Testing
The threat of security breaches is critical to any software application. When a breach is identified in an app, especially in a mission-critical app or app involving financial transactions, security threats become one of the tops searched keywords on the internet.
Mobile application security testing evaluates an app’s security from a malicious attacker’s perspective. Effective security testing begins with a thorough understanding of the app’s business purpose and data handling capabilities.
Here are several reasons to justify the importance of mobile app security testing:
The theft of users’ private data.
Deleting or modifying critical information stored in the app.
Financial transactions involving fraud.
Security breaches.
Upgrade Testing
Application upgrade testing is one of the most crucial steps in the mobile app testing process. It ensures that the app doesn’t crash when its version number has been upgraded, as mismatched numbers can cause glitches in its code. In addition to testing the installation process against the test scenarios, ensure to test the following aspects:
Ensure that the app-related data is retained and will not be lost.
Make sure that users’ sessions do not expire and that they are not prompted to log in again.
As much as possible, try to support backward compatibility of features in the latest version of an app and ensure that the upgrade succeeds even from a very old version of the app.
Test the duration of the upgrade process.
