Compatibility Testing is a type of software testing that ensures a product works correctly across different environments. This includes various operating systems, browsers, devices, and network conditions. The goal is to identify any issues that may arise when the software interacts with different configurations, ensuring a consistent user experience. During Compatibility Testing, testers evaluate how well the software performs in diverse scenarios. They check for functionality, usability, and performance issues that could affect users. By addressing these potential problems, developers can enhance the software's reliability and reach a broader audience, ultimately improving customer satisfaction.
