The common problem faced is the variety of approaches and each approach has its advantages and disadvantages. But to satisfy the benefits, challenges should also be addressed.  

Let’s look at the top challenges of mobile application testing in detail.

1. Several Types of Mobile Applications

The development of mobile applications has numerous benefits that include boosting brand visibility, building better user experience and bringing in new customers. Having that in mind, let’s now discover the three different types of mobile apps namely native, web and hybrid.

  1. Native apps

    The native mobile applications are built for a separate operating system. Therefore, apps that are built for Android do not work for iOS or other OS and vice versa. The common challenges in native apps include preserving the qualities and the compatible features.

  2. Web apps

    Similar to native applications, the web apps are enclosed within the website and rely on mobile browsers. Thus, web application undergoes various stages of check-up which is not only time-consuming but also has a high chance of failure.

  3. Hybrid apps

    Hybrid apps possess the qualities of both native and web apps and are expected to offer cross-platform reach. But at most times, these apps are affected by device fragmentations.

2. Different Screen Resolutions

Worldwide businesses produce smartphones with a range of screen sizesto attract a wide audience in the market. Consequently, different variants come with distinct screen sizes and resolutions. As a result, apps must be developed in conjunction with each new screen specification released on the market.

The display of an application on different devices depends on the screen size. This becomes a complicated issue for developers to concentrate on various mobile screens and includes regulating multiple screen resolutions and resizing the app.

3. Mobile Network Bandwidth

One of the significant parts of mobile application testing is mobile network bandwidth. Customers usually expect rapid mobile applications that the team must ensure. But it isn’t as easy.

An application that fails to generate faster results is considered poor in terms of data communication. When data is transferred between the client and the server, an application that has not been thoroughly tested and optimized to support a range of user bandwidth will experience latency.

4. Security Concerns

One of the major hindrances faced by mobile app testing teams is security concerns. Since mobile devices are prone to breaches, it becomes easy to trace the information through mobile applications unless vulnerabilities are tested. Secondly, poor encryption can drive hackers to steal data and therefore, developers must ensure that the encryption works well.

4. User Expectations

All over the world, the expectations of smartphones by users are different. Companies adhere to these expectations and provide variations to attract customers. However, this can take longer time and keeps the testing teams undergoing several levels of tests to accomplish the needs.

Apart from this, there are several other challenges to take into consideration including:

  • Strict deadlines

  • Heavy battery usage

  • Device fragmentation

  • Third-part integration

  • Battery life
