Smartphones became an important part of our everyday life and a lot of people can’t leave their home without them.
According to GSMA Intelligence, 5 billion people worldwide currently use smartphones and mobile phones! That is no less than two-thirds of the global population. No other device in the history of mankind has experienced such rapid market penetration. Entire areas of life are now influenced by the devices, and applications are now being (visibly and rather inconspicuously) integrated into cars, wearable technology, and home appliances.
Many daily situations rely on flawless app experiences and mobile users have incredibly high expectations when it comes to digital quality. Companies now realize this and are beginning to prioritize mobile.
Solve These Mobile Testing Challenges
Device fragmentation is one of the biggest challenges a team must solve. There are more than 25,000 Android devices alone on the market. Add that to the smaller, yet still complicated iOS device market and you have a difficult fragmentation issue on hand. User mobility is also complicating the further situation. This takes into account several variables when using the app like location, conditions, and network preference, to name a few.
And don’t forget about wearables, fitness bands, and IoT devices. They continue to flood the market, adding a new layer of mobile connectivity. So all these devices and their peculiarities should be considered when creating a mobile testing strategy.
Mobile Testing Strategy in Just Three Steps
Step #1: Identify Your Target Customer
With this data, a team can select the most appropriate mobile devices and wearables from their customer base and group them into priority clusters. This approach will help to reduce the number of test coverage during the development and testing phase. From here, the big decision is whether you should buy all the test devices, use a beta testing community approach, or try a crowdtesting solution.
A team has to decide for one of the options or a mixture of them. Please remember that testing on simulators and emulators are not the only test environments. Testing on simulators and emulators is perfect in an early development state, but when it comes to testing in-the-wild and in the usage scenario of the app, testing on real devices is a must.
Step #2: Define and Gather Your App Requirements
With the help of a designer (rather an interaction designer) and real users, app requirements are needed to define possible test scenarios. Based on these scenarios, your mobile development team can decide which devices will be used, which test data is needed to simulate the user behavior, as well as which environment the app will be tested in.
Here are some sample scenarios:
- The user must be able to log in to the app.
- The user must be able to register.
- The user must be able to search for products.
- The user must be able to view the shopping cart.
- The user must have the option to choose between different payment providers.
- The user must be able to synchronize the mobile app with wearable devices.
Scenarios like this will help to focus on the critical parts of the app and to prioritize the work during the development phase.
Step #3: Define Your Mobile Testing Approach
It is a process to create a mobile testing strategy and you should also be able to answer the following questions:
- Which part of the app can be automated and on which layer?
- What are the parts that can’t be automated and need intensive manual testing?
- Are there any hardware specific functions used by the app?
- What are the non-functional requirements of the app?
Mobile test automation plays an important role in the whole software development lifecycle of an app. However, it is not an easy task and should not be underestimated. When thinking about mobile test automation, keep the test automation pyramid in mind and decide on which layer a feature should be automated.
With the mobility of users, not every feature can be automated in an app. Depending on the use case of the app, automation on the end-to-end layer may not be possible at all. Therefore, it is important to identify the features which are difficult or not possible to automate. These features must be tested manually before every release.
While performing manual mobile testing, it is important to test the app in the environment where the customers will use it. Possible test environments could be your daily commute on the train, a trip into the woods, or while participating in a sports competition. As mentioned earlier, crowd or beta testing might help in this phase.
If the app uses hardware-specific functions like the camera or the different sensors, these functions must be part of the test strategy and must be prioritized based on the user scenarios. When testing against hardware-specific functions, it’s important to test on a wider range of test devices to cover the different hardware components.
Last but not least, the mobile development team must know the non-functional requirements of the app.
Non-functional requirements to think about are:
- Load & Performance
- Internationalization (I18N) and Localization (L10N)
It is important to plan these non-functional requirements into the design, development, and testing phases.
Testing is important
As the software moves forward in the SDLC, the cost to fix bugs increases exponentially. With the help of a comprehensive mobile testing strategy, bugs can be identified in earlier stages while keeping the overall process fast, lean, and efficient. So stop compromising on digital quality and take the time to choose the proper testing approach for your app or game.
