Mobile app development has become increasingly complex, with larger teams and more diverse modules required to serve millions of users worldwide. One of the challenges faced by mobile teams is device and OS fragmentation, where different devices and operating systems can cause performance issues or display problems. To address this challenge, continuous testing has been introduced as a practice of testing software as part of the development process, rather than waiting until the end of the development cycle to perform testing. Sauce Labs is a cloud-based testing platform that allows mobile engineers to run automated and manual tests on a wide range of virtual and real devices, using tools such as Espresso and XCUITest. By integrating Sauce Labs with Bitrise, a Mobile DevOps platform, developers can easily run their mobile UI tests on every code change, pull request, tag, or during nightly builds, reducing the time and effort required to test applications manually and catching issues early on in the development process.
