You could visualize it as an encrypted, verified, and shared Google Document. Each entry i...

SDLC for a mobile program can become messy, tedious, and quite challenging due to its intricacy and variability. An integral part of the process that arguably has one of the largest impacts on the outcome is QA. To streamline the testing procedures and make the development less strained, let’s dive into the commonalities and specialties of mobile app testing.

Particularities of Mobile Testing

When it comes to mobile QA, there are some subtle aspects that distinguish it from desktop and web app testing. In particular, while working with a mobile application, consider the following:

1. Installation / de-installation / update process.
2. Location & VPN.
3. Data synchronization.
4. Interruptions of the application by cells, messages, etc.
5. An ability to run the app in the background.
6. Payment gateway.
7. Communication (chat, ...

It’s no secret that any app built for mobile devices needs to be tested for compatibility. The mobile landscape nowadays is highly fragmented. It spans hundreds of devices across manufacturers and models. If testers don’t have access to the actual testing devices they need, it is still not a reason to skip the testing process. The solution is using virtual devices. So here is the comprehensive list of 10 best Android emulators for PC and other platforms to test your websites.

What Is an Emulator?

Firstly, testing an app on one smartphone doesn’t guarantee it will function the same way on other devices. Secondly, when there is no possibility to run a test on a real Android device, mobile QA specialists use emulators. An emulator is a virtual testing tool that allows replicating the functionality of mobile devices on PCs. With its help, you can mimic various operating systems, web browsers, and hardware. How does it work? All mobile devices use a special set of...
