H2K Infosys highlights that various programming languages play an important role in AI testing, based on specific testing needs and the AI technologies being used. Python remains the leading choice due to its extensive support for AI development and automation tools such as TensorFlow, PyTorch, and Selenium. Java is commonly preferred for large-scale enterprise AI solutions and automated testing environments. R is especially valuable for data analysis and verifying machine learning models. JavaScript is helpful for testing AI-driven web applications, while C++ is ideal for high-performance AI systems that require speed and efficiency. Learning these languages enables testers to automate AI processes, evaluate machine learning accuracy, and maintain reliable AI performance across multiple platforms and practical testing scenarios.
