By simply deploying the application and using a test automation framework such as Selenium for the web or Appium for mobile to automate interactions, it is also possible to run automated test scripts on these devices.
Teams are responsible for setting up as many devices as the environments they wish to test on since the test environment is typically the real testing device.
Advantages of real device testing
There are various benefits to real device testing, which tests websites or software programs on real hardware as opposed to emulators or simulators. They are:
- Accurate representation: Hardware variances such as screen sizes, resolutions, and CPUs and software configurations like operating system versions and device-specific applications are accurately reflected in real devices’ representation of the actual user experience.
- Real-World conditions: Testing on actual hardware enables the simulation of real-world circumstances that can impact the usability and performance of apps, such as network hiccups, battery life, and environmental variables.
- Behavior accuracy: In terms of touch sensitivity, gestures, and hardware interactions, real devices frequently behave differently from emulators or simulations. Accurate assessment of these behaviors is ensured by testing on actual devices.
- Performance testing: To optimize app performance, real devices offer more precise performance measurements, such as CPU utilization, memory usage, and reaction times.
- Hardware-Specific problems: Owing to quirks in the hardware, some problems may only appear on particular devices (e.g., camera integration, GPS functionality). Real-world device testing aids in locating and resolving these device-specific problems.
Disadvantages of real device testing
Although real device testing has numerous benefits, it also has drawbacks and difficulties of its own:
- Cost: Maintaining up with a wide variety of genuine gadgets can be costly, especially in light of how frequently new models and updates are released. This cost covers not only the initial purchase of the gadgets but also their upkeep and management.
- Restricted availability: Not all devices on the market may be accessible to the organization due to resource constraints, which could result in gaps in the coverage of devices for testing.
- Time-Consuming: Testing on actual devices might take longer than testing on emulators or simulators because of things like device deployment, setup, and device-specific debugging problems.
- Version control: It might be difficult to keep track of many operating systems and software versions on devices. Compatibility problems may arise from the need to ensure compatibility across various versions and setups, which can demand extra work.
- Security problems: Data privacy, access control, and the possibility of sensitive information leakage are security problems raised by testing on actual devices, particularly those that are used by employees or that are accessed through cloud services.
Emulators
Software that replicates the hardware and software of the intended device on the computer is known as an emulator. They accomplish this by employing binary translation to convert the instruction set architecture of the target device to that of the machine that is used to perform the tests.
Emulators are relatively similar to one another in one way or another, with the shared objective of establishing desktop virtual environments where testers can simply and flexibly conduct real-life test cases, assisting quality assurance teams in understanding how the application functions in various settings.
Advantages of Emulators
Emulators provide various benefits for software development and testing. They are stated as below:
- Cost-effective: Compared to buying and maintaining a large variety of real devices, emulators are usually free or very inexpensive. Because of this, smaller teams or projects with tighter budgets can use them.
- Accessibility and availability: Regardless of a team member’s actual location, emulators are easily distributed and widely available. Collaborative testing is facilitated by this accessibility.
- Fast deployment: Compared to putting up physical devices, emulators may be swiftly set up and configured, enabling the deployment of test environments more quickly.
- Controlled testing environment: Hardware configurations, software versions, and network circumstances can all be emulated and changed as needed in a controlled testing environment that is offered by emulators.
- Automation: Because emulators enable the establishment of repeated test scenarios that can be completed without the need for human interaction, they integrate well with automated testing frameworks.
Disadvantages of Emulators
Despite their benefits, emulators have a few drawbacks that need to be taken into account. They are:
- Performance variability: In terms of processor speed, memory management, and graphics rendering, emulators might not be able to faithfully simulate the performance characteristics of real devices. False positives or negatives in performance testing may result from this.
