Build and Test Java Applications Using TestNG

By the end of this course, learners will be able to design Java applications using POJO classes, implement menu-driven console user interfaces, apply validation and exception handling techniques, and automate testing of business logic using the TestNG framework. This hands-on Java TestNG Case Study course guides learners step by step through the complete lifecycle of a real-world customer management application. Starting with project planning and data modeling, learners progressively build application logic, handle user input, enforce validation rules, and manage exceptions to ensure application stability. The course then transitions into automated testing, where learners write and execute TestNG test cases to validate customer data, business rules, and overall application flow. What makes this course unique is its case-study-driven approach, allowing learners to see how core Java concepts, validation, exception handling, and TestNG testing come together in a single cohesive project. Instead of isolated examples, learners gain practical experience by building, testing, and evaluating a complete application from start to finish. Completing this course equips learners with job-ready Java development and testing skills, strengthens logical thinking, and builds confidence in writing maintainable, testable Java applications suitable for real-world projects
