Starting from version 11, it is displayed as AI (formerly known as PostBot) in the Postman desktop application.
Validate model accuracy with k-fold cross-validation by splitting the training data into k folds, training on k-1 folds, validating the remaining fold, and averaging results with fixed hyperparameters.
This course is designed for QA Engineers, Automation Engineers, and SDETs who want to learn how to test Machine Learning (ML) and Generative AI (GenAI) systems across their complete lifecycle.
Traditional software testing techniques are not sufficient for AI/ML systems, where behavior depends on data, probabilities, and model decisions. This course teaches practical, real-world testing strategies to validate accuracy, reliability, fairness, robustness, and performance of ML and GenAI models.
You will learn how to test AI/ML systems at every stage:
Early-stage testing during model development
Functional and evaluation-phase testing
API-level automation for ML models
Responsible AI testing for bias, fairness, and ethics
Post-deployment monitoring and drift detection
The course includes hands-on demos, real-world examples, and quizzes, covering supervised, unsupervised, reinforcement learning models, and Retrieval-Augmented Generation (RAG) systems.
By the end of this course, you will be able to design and execute comprehensive testing strategies for AI/ML systems used in enterprise environments.
