Appium is favored because it’s language-agnostic, open-source, and supports both Android and iOS. Unlike frameworks like Espresso or XCUITest, Appium doesn’t require access to an app’s source code, allowing greater flexibility for QA teams. It integrates seamlessly with CI/CD tools such as Jenkins, GitHub Actions, and Bitrise, enabling continuous testing pipelines. Moreover, its community support is vast, offering frequent updates and shared libraries. Many companies in New York, USA, prefer Appium because it supports both native and hybrid apps with one unified framework, cutting down maintenance costs and enabling faster testing cycles for scalable products.
