It also helps you to test how several factors can impact your application. In order to make sure that you have a better mobile app, here are some amazing mobile testing strategies that can help you to test your app and make sure that the apps are reliable, trustworthy, and is easy to use.

Firstly what you need to identify is your requirements. This can be done by creating a flowchart for the app. This can help you to decide if you need the native apps or the hybrid apps. You also need to identify what devices do you need your users to use your app. Testing applications on mobile devices are more challenging than testing the web apps on the desktop. It is because the mobile devices have different screen sizes and hardware configurations wide varieties of mobile devices, different mobile operating systems, different versions of the operating system, different mobile network operators, frequent updates etc. Another big challenge of the mobile application testing is that the mobile screen is smaller and have less than that of the desktop.

The mobile application testing can be categorised as:

  • Cross Platform Testing
  • Functional Testing
  • User Interface Testing
  • Localization testing
  • Accessibility Testing
  • External Factors Testing
  • Performance Testing
  • Security Testing

In order to perform a proper app testing, the steps mentioned below can help you to do so.

Know Your Customers:

Know your customers

Knowing your customers and your user’s expectations are the first and foremost aspect of your business. It is because different mobile users have different expectations from their mobile devices and are relatively larger than their desktops. Hence it is necessary that you have a proper idea of your target customers, their expectations, age, gender, monthly income, mobile usage habits, geographical location, and other such information to get a better picture of your customers. This can help you to understand your customer’s usage patterns and help you to do a proper mobile app development and mobile app testing appropriately in your business. It also helps in facilitating the testing and helps you to focus on the devices that you need to target and also downsize your testing efforts as you only need to test the devices that your customers use. This can be done with the help of interviews, conduct market research, and make use of mobile app stores statistics.

Create Different Device Groups:

One of the ways in which you can choose to test the apps in different scenarios. This can be done based on the knowledge of the customers and the types of mobile they use. Here different groups of devices can be created and can be specified with a different priority. Different mobile devices can be added to this target group that can help you to decide which features need to be implemented on which device groups and what needs to be exempt from it. Hence during testing, the app tester need to focus on testing on the established group devices and can help speed up the process.

Follow Standard Test Methods:

It is necessary that the software testers are familiar with software testing terms and techniques. These include the elements such as boundary values, equivalence classes, various coverage types, acceptance, etc. Apart from these, the functional and nonfunctional testing skills of web or desktop applications are required. For mobile testing, you also need to implement some modifications.

Test For Major Hardware Features:

Test for major hardware features

 

Different mobile devices are filled with different hardware that helps the users to interact with users and their surroundings with the help of the mobile device. Along with the basic hardware, the smartphones also come fitted with various sensors that can help you to make the most out of your smartphone devices. Some of these sensors are:

  • Ambient light sensors
  • Humidity sensors
  • Proximity sensors
  • Acceleration sensors
  • Gyroscope sensors
  • Magnetic sensors
  • Pressure sensors
  • Location sensors
  • Touchless sensors
  • Temperature sensors

Apart from these, many new sensors are added on a regular basis. These sensors can be used within the mobile app and hence it is necessary that you test your app for different sensors and make sure that the app works in the way in which it is intended to do. This can be done by testing the app in sensor-specific scenarios. It also needs to be tested in different environments and light situations. Apart from testing the sensors, it is also necessary that you test the mobile app against different hardware features of the device like the camera, display, storage, microphone, etc.

Test On Different Data Networks:

Test on different data networks

Various apps make use of data networks to access your internet. Mobile apps that require you to have an Internet connection to carry out your task. Hence, it is necessary that you test it in various data networks i.e. Fast data networks like LTE, 3G, or Wi-Fi and also in the slower networks like EDGE or even GPRS. It can also help you to test various types of data networks and also test how your mobile apps perform. Hence it is necessary that you test that the mobile app works with different network speeds and handle network transitions from LTE to EDGE with ease. To order to test these scenarios, it is necessary that you try it in different network scenarios and network carriers.

Test In Different Languages:

If your mobile apps are to be used in different countries, it is necessary that you support your app in different languages. Hence it is necessary that you test the app in different languages, characters, and sizes. It is necessary that your app is consistent in different language, is clear, and is able to convey your information quite easily. It is also necessary that you choose a proper font for each language you use that is consistent with the app.

Test Standby, Interrupt, And Battery Issues:

In order to make sure that your mobile device offers the best performance, you need to conduct certain tests. The standby test states that the mobile app can handle the standby mode. You also need to test for any UI glitches, data handling, and other errors to make sure that the app maintains their state while entering and leaving standby mode. It is important that you test that the mobile app updates the last used view at the end of standby mode. It is necessary that the app must update the current view to get the latest data from the back-end.

You also need to conduct the interrupt test. Here you need to select several mobile devices that have multiple apps installed and create notifications on your device. This can enhance the performance of your app and get better responses from the users. Here you can also look for app crashes, freezes, UI glitches and also choose the option to check for the performance of the apps.

Testing the battery consumption of the app is necessary as it helps to get an idea what amount of battery is consumed. Huge battery consumption can result in the uninstalling of the app. It is necessary that during the start of testing the battery is fully charged and note the battery of the state to get an idea of the battery drain. It is also necessary that you test the mobile app with a battery charge of 10–15%, as a majority of these devices enter the battery-saving mode and disables some hardware features of the device. This helps you to find bugs in the case of turned-off hardware.

Test Install, Uninstall And Updates Procedures:

Test install, uninstall and updates

The install, uninstall and updates are the important aspects of the life of the app. It is necessary that you test the app updates and installation process. It is necessary that in the update process you simulate the updating of the app from the older version to the latest one. In such a case it is necessary that the user’s database changes do not impact the user’s database updates. It is also necessary that during install and uninstall tests you look for crashes or any other problems. After the uninstallation process, it is also necessary that you check the device storage to ensure that the complete removal of app data has taken place.

Restrict Permissions And Check Log Files:

It is necessary that you choose the option of best practices for mobile app testing with appropriate app permissions and log files. You need to also verify that you provide the app with only those permissions that it require. Apart from that, the log files must be checked thoroughly to look for errors, stack traces, warnings, etc. It is also necessary that the log files must be set to the release mode as it helps to avoid showing too much information to others.
