To manage this, device farms come into a place where its features provide a cost-effective option by hosting a large number of devices on a cloud-based framework. Testing efforts can easily be scaled up or down as per necessity since there are no hardware costs involved.

Device connectivity

Device farms provide testers with the command to simulate different connectivity and network situations as during testing, problems with device connectivity can occur which can often compromise the validity of the testing results.

Following this provides an idea of real-world conditions in which the device operates. App’s behaviour can also be checked to see the battery consumption, requirement of network bandwidth, behaviour in case of low battery percentage or if the device turns off unexpectedly, interaction with other features of the device like GPS or Bluetooth, and performance.

Conclusion

In conclusion, the above benefits of using device farms represent why they are the best option for testing. Having access to various devices makes mobile testing cost-effective and more accurate. Though testers can test the app’s behaviour virtually using a simulation of the mobile device, the chances will be very high that some aspects might get overlooked, or bugs might be unearthed while testing on the physical device.

Device farms provide more developed techniques and access to real devices, which makes them a better comprehensive solution for mobile app testing. However, developers still need to write, manage, and update automated tests. A hybrid approach where combining manual testing with automation may work better In certain scenarios. Overall as part of a comprehensive testing strategy, choosing device farms is a valuable tool, complementing in-house testing environments and enabling continuous testing across an expanding matrix of devices and platforms.
