Android app testing emerged almost simultaneously with Android app development in the mid-2000s. The first Android software development kit (SDK) was released in 2008. QA engineers tested the first Android apps manually, installing them on different devices and executing tests to identify issues and bugs. By that period, the number of such apps was relatively small. Since then, everything has changed.
According to Statista, the global number of app downloads has reached 257 billion. Techcrunch informs that the Google Play Store contains over 3.7 million apps, while the Apple App Store has 1.7 million.
The number of apps downloaded yearly increased by 82% between 2016 and 2022. The most significant market share belongs to apps with Android operating systems: 69.9%, while iOS has 29.3% and there are 0.7% others.
Now, could you imagine if developers and testers were still using manual testing? The emergence of automation testing tools was an inevitable result of the whopping number of Android apps that are developed every year. This is the key reason why the global testing market can reach $109.5 billion in 2027.
Of course, the question is not only about quantity but also about quality. 71% of uninstalled apps incur due to crashes. This means that you need to stick to a diligent approach while selecting a robust Android app automation testing tool.
This article discusses the best Android app automation testing tools. We will also reveal what Android app automation testing is, the benefits of automation testing tools, and what you need to consider while choosing the relevant automation testing framework for your project.
So, let’s uncover the basics, starting from the meaning of Android app automation testing.
Understanding Android App Automation Testing
Android automation testing is a process of testing Android applications using specific automation testing tools. Developers launch test scripts to check apps’ performance and functionality.
