Testing is a fast-paced industry that is constantly changing. The movement towards mobile devices has brought a whole different set of challenges to the testing world. Not only have consumer targeted apps set the trend, but enterprise apps have also made the move to mobile. Mobile users are not forgiving and finding an issue out in the wild might mean leaving the application for good. Mobile apps and websites need to be rock solid before they are released to the market. Testlio is focused on mobile app testing and we’ve identified 6 key challenges that app developers and testers are facing.
1. Screen sizes
The Android world is not simple. The variety of different aspect ratios and pixel densities can be overwhelming. With the launch of iPhone 6, Apple brings new screen sizes to the iOS world as well. Though iOS developers are used to pixel perfect screen design, they now need to change their mindset to the adaptive screen design instead. For testing, it means that we need to check on various devices that all the necessary screen elements are accessible with different screen sizes and aspect ratios.
2. Connection types
There are several standards for mobile data connections (edge, umts, 3G, 4G) as well as for wifi (b, g, n). Sometimes there might be no connection available at all or the device is in flight mode. When users move around the connection type might change. Unfortunately some carriers filter the web on their own will, which results in the devices being connected without actually having connection with a specific service (messaging or calling through apps). Even though connection API’s on mobile platforms have been developed keeping those challenges in mind, the real world environment is still very much varying and interesting set of issues may occur. It’s important to test the bandwidth usage as not all carriers are supporting unlimited data volumes.
3. Different OS versions
iOS users are known to be upgrading quickly to the newest versions (iOS 8.0 uptake has been around 50% during first two weeks). On the contrary, Android uptake has historically been very slow and the fragmentation is wide. This means that app developers need to support older OS versions and older API’s, and testers need to test for those.
4. Power consumption and battery life
The innovation in the battery storage capacity field hasn’t been as quick as in the app consumption. We are running lots of apps during the day and several processes are running on background without us even noticing. This all requires cpu cycles which on it’s turn require power and thus the batteries tend to dry. When testing mobile apps we need to make sure that the power consumption is kept minimal and the app is developed by keeping the best practices in mind.
Mobile device screens are relatively small and there are always more data we would like to present than possible to fit to the screen. It’s challenging to keep the interaction clean and simple for the user, and at the same time display all the necessary information. Font size and readability are other challenging factors of usability. When testing mobile apps it’s important to pay attention to the size of click areas and making sure that all texts are readable without lenses.
Most of the apps are designed to be used in international markets. Testing for translation is only one piece of the whole localization testing. Testers should also take into account regional traits (locale settings, timezones) and target audience. Changing time while the app is running might cause some interesting artifacts. Also, some designs that are working in the western world might not work in the east and vice-versa. Right-to-left languages have always kept developers puzzled.
Together with our community of expert testers and tailored tools, Testlio helps to overcome those challenges. Through community we have access to enormous pool of different devices and clients can let their apps to be tested exactly on the specified devices. With automation scripts we can check the main workflows on various emulated devices.
Testlio’s strength comes from testing in the real world environment with real users on real devices. This means that testers catch issues that are not common in laboratory conditions. For example, we have experienced situations, where some screen elements were not understandable in the bright sunlight and users, had no idea which button they should click. Our testers have different internet connections and bandwidth usage that changes over time. This is what also happens with real users. Testlio helps you to discover those issues before your customers do.
Testlio community is widespread all over the world. We have some testers in every corner of the world and they are the ones who know best their local traits and can make sure that apps under test take those details into account. It’s always a good idea to run your translations through a native speaker who also understand the local market.
Testlio helps app developers uncover issues before their customers do with a software testing solution that’s networked, on-demand, scalable, and focused on quality. Talk to us for a demo.
