Teams can find possible problems with performance, dependability, and user experience that might not be seen in controlled testing environments by exposing the product to these real-world scenarios.
Faster Testing:
Teams can accelerate the delivery of high-quality software by using parallel testing on several devices to speed up the testing process and produce faster feedback loops.
Teams can save a lot of time testing by using parallel testing across numerous devices at the same time, as opposed to sequential testing approaches. By dividing the burden among several devices, this method maximizes the efficiency of test execution and permits the execution of multiple test cases at the same time. Teams are able to evaluate changes and iterate quickly as a result of the significant reduction in testing time.
Additionally, simultaneous testing improves resource use and scalability, especially in situations where testing requirements are beyond the capabilities of individual devices or testing environments. Teams can expand their testing efforts to handle bigger test suites, more test coverage, and an increasing number of supported devices without sacrificing testing efficiency or speed by utilizing parallel testing.
Types of Device Farms
Device farms come in two types, each offering unique advantages tailored to the specific needs and preferences of testing teams. Let’s discuss the both types in depth:
1.Cloud-Based
Cloud-based device farms, such as LambdaTest Device Farm, enable remote access to a large pool of devices via a cloud service provider. With this technique, teams may increase their testing efforts dynamically based on project requirements without having to make an upfront investment in hardware or infrastructure because of its scalability.
Additionally, LambdaTest provides access to a real device cloud, enabling you to test your app or website across a wider range of browsers, operating systems, and device configurations. This can help ensure a seamless user experience for a larger audience.
Furthermore, since the LambdaTest handles device provisioning, maintenance, and upgrades, it does away with the inconvenience of device maintenance. In the end, this increases efficiency and speeds up the testing process by giving testing teams more time and resources to devote to testing activities rather than device administration.
2.On-Premise
Conversely, on-premise device farms entail the upkeep of an actual collection of devices within the premises. This method gives you more control over data security and technology, but it does need upfront infrastructure and hardware investments.
Since testing teams have direct access to the devices, they may customize and control the testing settings to a greater extent. Furthermore, in circumstances where internal testing is required due to data security and compliance constraints, on-premise device farms might be the better option.
