It's 3 AM, and during the testing process, your mobile app crashed in the middle of high traffic. Your outdated test infrastructure is unable to mirror real-life scenarios fast enough, and serious problems go undetected.
On the other hand, a competitor provides a seamless user experience as they embrace Cloud-Based Testing and gain unmatched flexibility of open devices, speed of finding defects with their rapid scalability.
By 2025 Cloud-Based Automation Testing will no longer be optional; it is now the basis of software delivery.
It allows teams to run tests, as-needed, on thousands of environments significantly improving testing efficiency, without having to worry about complexity or cost from managing internal infrastructure.
Whether a start-up testing their first release, or an enterprise managing complex, multi-platform communities, cloud testing solutions impact the reliability, time to release, and competitive advantage of your business.
What is Cloud-Based Automation Testing?
Rather than relying on local servers, cloud-based automation testing utilizes cloud infrastructure to run the test tools, frameworks, and virtual infrastructure required.
During test execution, the cloud supplies the needed computing capacity, storage, and network resources to execute the automated scripts.
Definition and importance
Cloud-based automation testing is a new software testing method that utilizes cloud computing infrastructure to execute automated test scripts over various browsers, operating systems, and real devices.
Cloud enables teams to easily spin up an array of virtual testing environments, concurrently execute tests across multiple devices and operating systems, speed up software releases, and lower costs all at once.
Thereby avoiding the expense of maintaining your own infrastructure, while testing teams can quickly simulate user conditions.
