Introduction of Effective Unit Testing

Effective Unit Testing covers the essential techniques and best practices for writing and maintaining high-quality unit tests. Participants will learn how to write tests that ensure code correctness, improve code reliability, and maintain software quality throughout the development lifecycle. This training focuses on the core principles, tools, and frameworks used in unit testing, providing practical skills for both beginners and advanced learners.

Prerequisites:

1. Basic knowledge of programming concepts (preferably in Java, C#, Python, or similar).
2. Familiarity with software development and testing principles.
3. Experience in writing code or working in a development environment (helpful but not mandatory).
