In automation testing, specialized software tools are used to run tests on applications, comparing their real-world results with anticipated results. In real device automation testing (RAT), applications are tested on real physical devices, rather than using emulators and simulators, thus providing a more precise representation of how an application will perform under real-world conditions.
Streamlining the Testing Process
Automation testing speeds things up by running tests on different devices at the same time. This means you don’t have to wait as long to make sure your app is compatible and running smoothly. This means your development team can keep up with the ever-changing market and keep releasing updates faster.
Enhancing Product Quality
Automation testing makes sure every test scenario is done exactly the way it’s supposed to be done, so there’s less room for human mistakes and you get a full coverage of your test cases. This means you can spot and fix critical issues early on in the development process, resulting in a better product in the end.
Realizing the Benefits of Automation Testing
Real-world Testing
Automated testing performed on real devices is a powerful approach that reproduces the user experience in the real world, providing a unique advantage in detecting problems that may remain latent within simulated environments, thus providing a more thorough and precise evaluation of an application’s performance and capabilities.
Comprehensive Testing Coverage
Automated testing lets you test on real devices, so you can test against a bunch of different devices, OS, screen size, and hardware. This way, you can see if there are any issues with different user scenarios, so you don’t miss out on any important bugs. Manual testing is usually limited by how much time and resources you have, but automation can do a lot of testing in a short amount of time with lots of different devices and scenarios. This means you can test all kinds of things, from edge cases to rarely encountered scenarios, so you can get a more reliable and robust app.
Realistic User Scenarios

Realistic user scenarios are those in which the user interacts with the application in a realistic manner. This allows testers to accurately simulate user interactions in order to identify issues that may only arise during real user interactions, thus providing a more precise assessment of the behavior and performance of the application.
Real devices are a reflection of the complexity of user interactions. Users interact with applications in a variety of circumstances and environments, such as varying network strength, battery capacity, and device orientation. While simulated environments may be useful, they do not fully capture the complexities of such real-world interaction. Automated tests on real devices expose applications to these various scenarios, revealing issues that may only appear under specific conditions.
Consistency and Accuracy
Manual testing is important, but it’s full of mistakes and inconsistencies that humans can make. Even the best testers can miss things or make mistakes when doing tests. Automation takes care of this by running tests with accuracy according to predefined scripts. This means every test iteration is done exactly the same way, so there’s no chance of getting a false positive or negative because of human error.
Performance testing is done on real devices to get an idea of how an app works under real-world conditions, like different network strengths or battery levels. That way, you can make sure the app is running as it should and avoid performance issues that could affect user satisfaction.
Identifying Device-Specific Issues
Each device and operating system has its own unique set of hardware and software properties that can cause it to behave differently. With automated testing on actual devices, you can spot any device-specific problems that might not show up in a simulation. This way, you can make sure the user experience is the same on all devices.
Usability and User Interface
UI and usability testing is essential for providing a pleasant user experience. Utilizing automation on real devices, you can accurately test touch interactions and screen layouts, as well as UI responsiveness, to ensure that your application is easy to use and easy to understand.

UI and usability issues determine the success of an application. Utilization of automation on real devices enables you to perform full-scale usability testing by simulating user interactions on a wide variety of devices. Through this testing method, you can identify touch responsiveness issues, screen layout issues, and usability issues that may not be visible in a simulated environment.
Early Bug Detection
The integration of automation testing into the development process allows for continuous evaluation as new features are implemented or code is altered. This allows for early detection of potential issues through automated testing on existing devices, thus preventing them from becoming more difficult and costly to rectify in the later stages of development.
Faster Testing Cycles
You can run automated tests on multiple devices at the same time, cutting down on the amount of time it takes to test. This means development teams can speed up their testing cycles and release updates faster, helping them keep up with the speed of development.
Regression Testing
Automated tests are great for regression testing, which is when new code is tested against existing functions. This helps avoid any potential issues and makes sure that any new features or changes don’t mess with anything that’s already working. As your software grows, new features come out and existing code is changed.
Regression testing makes sure that these changes don’t introduce any new bugs or break any existing features. Automation testing is great for regression testing because you can run automated test suites as often as you need. That way, when you’re making changes, you can be sure that any issues will be caught and fixed quickly.
Network and Connectivity Challenges
Network connectivity is a fundamental requirement for many applications, and network conditions in the real world can vary significantly from one application to another. Through automated testing on actual devices, network strengths, network congestion, and connectivity interruptions can be simulated to gain insight into the performance of an application in the face of these challenges. It is important to note that simulated environments may not accurately capture the complexities of network interaction and its effects on user experience.
