6 Best Mobile App Testing Tools for Android & iOS

With each passing day, the number of smartphone users continues to grow. People increasingly rely on mobile apps to live through their daily routine and maintain a modern lifestyle. Our reliance on phones is highlighted by the fact that smartphone users, on average, check their phones 58 times a day.

As the demand for mobile apps increases, so does the number of apps developed. Researchers at Statista found that there had been 204 billion app downloads in app stores in 2019 alone. Likewise, the number of mobile developers has increased, with some estimates putting the figure to 12 million. 

However, because of the sheer number of applications available to the market, mobile developers have to compete with others to gain the most following within the market. They must ensure that their product has the best quality and meets all requirements of their target market. 

That said, without software testing, there is no way to ensure either of those things. For this reason, software developers and QA teams are in constant search for the best mobile testing tools to ensure the highest quality of mobile apps.

To help our readers, we have compiled a list of the mobile testing tools for both Android and iOS applications. By noting each tool’s key features, strengths, and weaknesses, we will help you choose the best mobile testing tools for your business.

mobile application testing tool

EarlGrey

Developed by Google, EarlGrey is an open-source native test framework used for UI test automation in iOS. This framework is also used internally by Google for functional testing of native iOS apps like Youtube, Google Calendar, Google Photos, Google translate, and others. It gives QAs access to enhanced synchronization features for stable UI testing.

The built-in synchronization is a key feature that enables test scripts to wait for specific UI events to occur before directly starting an interaction with the application UI. EarlGrey automatically synchronizes with the UI and network requests; however, it still allows a user to implement the customized timings manually.

Conclusion

Mobile application testing has a significant impact on the performance and success of your application. It maximizes the performance, capability, and quality of a mobile app while validating its core functions. 

Choosing the best mobile app testing tool can help you and your team identify critical problems within the software. That said, ultimately, a mobile testing tool is just a tool itself. Unless your team has proper training and knowledge to make use of that tool, it wouldn’t create value for you.

Moreover, every mobile testing has limited functionalities in one way or another. Users have to supplement the lack of features with the expertise of testing professionals. This is why to build high-quality software, you need a reliable testing service with expertise in mobile testing.
