Description

Training Introduction:

The course “Test-Driven Development (TDD): Best Practices for Agile Teams” is designed to introduce participants to the principles and practices of Test-Driven Development (TDD), a core methodology in Agile development. TDD emphasizes writing automated tests before the code itself, which leads to cleaner, more reliable, and maintainable software.

This course focuses on the benefits of TDD, such as improved code quality, better design, and early detection of defects. Participants will learn the process of writing tests, coding solutions to make tests pass, and refactoring for simplicity and clarity. Additionally, best practices for integrating TDD into Agile workflows are covered, enabling teams to work more efficiently and deliver higher-quality software.

Prerequisites:

• Familiarity with at least one programming language (e.g., Java, Python, C#, etc.).
• Basic understanding of unit testing concepts.
• Knowledge of Agile methodologies is helpful but not mandatory.
