Automating desktop applications remains crucial for businesses despite the rise of web and mobile apps. Desktop applications are integral to many critical business processes, necessitating robust testing to ensure functionality across diverse environments. WinAppDriver, an open-source framework initiated by Microsoft, facilitates this by enabling automated testing of desktop applications similar to web and mobile apps using Selenium and Appium. It supports a variety of Windows applications and integrates with popular CI/CD tools, making it a versatile choice for developers familiar with these frameworks. The blog details the installation and operation of WinAppDriver, highlights the importance of selecting the right automation tools, and demonstrates testing strategies for desktop applications, emphasizing the necessity of a scalable testing infrastructure. It also explores cloud-based testing, particularly using LambdaTest's HyperExecute, for efficient and scalable test execution, ensuring a high-quality product release.
