Why are hybrid apps most challenging to test?

Mobile testing is a critical measure in the mobile application development process as it ensures that a quality product is delivered to the end user, but also it’s a measure of how well requirements were adhered to and is a continuous learning tool for process improvements (e.g., how do we avoid these bugs in the future, how do we find them quicker). With device fragmentation and rapid changes in device software, it’s even more important in the mobile world that the testing function does not just ensure quality, but that it continues to improve on the process of ensuring quality.

So in your quest to ensure the best ROI, performance and quality are key. In other words, you need to test your application pre-launch and also continue to test and monitor post-launch to ensure continued high performance. Mobile testing not only includes functional testing, but also usability and performance testing.

Hybrid apps pose the most challenge for testers because they’re combo apps – they use both native and Web objects to provide a seamless user experience. That just means when testing hybrid apps, testers need to address characteristics of both native and mobile web apps collectively. Those characteristics are mobile web objects and native objects all wrapped up in a single hybrid app. In order to succeed you need to be able to easily differentiate between mobile objects and native objects so you can test accordingly.

The ability to interact with all objects appropriately based on object type is important. For example, you need to know that interacting with an HTML 5 object will be a little bit different than interacting with a corresponding native object. You just need to anticipate these differences and create tests accordingly. Your test strategies for mobile applications should also include information verification for all of the app types noted above. Since most apps pull in information from a Website, it’s important that when you test, you ensure the Website is providing the right information to the app.

Furthermore, you need to be aware of other factors that web objects present to an application. For example, are there security holes that allow unwanted access to the device? Are there online and offline differences that hybrid apps allow? If there is no outside access, does the application behave differently? And finally, do the hybrid Web objects have performance problems? All of these questions need to be considered. At the end of the day, a solid mobile application testing strategy is the first step no matter what kind of app you’ll test. The right strategy can mean the difference between highly functioning, reliable apps and an app with poor performance and bad reviews.
