App developers for Android-based and Amazon Fire-based mobile devices like smartphones and tablets now have access to an AWS-maintained stable of actual, real, mobile hardware on which to test their new apps. In its announcement AWS said:
Developers can upload their apps and run tests simultaneously on all of the most commonly used mobile devices across a continually expanding fleet that includes the latest device/OS combinations.
Most developers currently test new apps either on a relative handful of hardware devices or by using a software emulation program to simulate how their apps will behave on a real device. As a developer might say, neither is optimal.
According to AWS:
Developers can use AWS Device Farm to test real-world customer scenarios, fine-tuning test environments with a broad set of device configurations, including language, location, app data, and app dependencies. AWS Device Farm also makes it easy for developers to focus on the most important issues by providing comprehensive, actionable reports as tests are completed. AWS Device Farm automatically identifies and groups identical errors across multiple devices, allowing developers to quickly and efficiently analyze data from potentially hundreds of tests.
Variations in how different device makers implement Android make testing an app on all those devices challenging. That is the audience the device farm addresses. There is no need to include Apple’s iOS because there is just one version of the operating system and developers don’t have to buy hundreds of devices in order to test their new apps.
AWS assesses no set-up charges and developers “pay as they go.” According to the website, the first 250 minutes of testing time are free. After that AWS charges 17 cents per device minute. Alternatively, developers might choose to pay a flat monthly fee of $250 for unlimited testing time.
