By applying TDD at the level this course provides, you will create more reliable and flexible code, promoting scalable and high-quality solutions through automation.

Improved code quality: Ensures code quality, reduces errors, and makes it easier to add new features. You can verify that your code works as expected.  
Regression testing: Ensures that functionality remains intact after making changes. TDD makes this process more manageable by enabling fast and simple testing.  
Maintenance and scalability: TDD reduces risks related to software maintenance and scalability, as well-designed and tested code is easier to maintain and scale.  
Increased customer satisfaction: Developing a higher-quality product enhances customer satisfaction and loyalty.  
Long-term cost reduction: TDD helps lower long-term costs by reducing the time and resources needed to debug errors.  
Faster time to market: TDD facilitates continuous integration and delivery (CI/CD), speeding up the launch of new products and features. You'll receive quick feedback on the state of the code and can identify issues in the early stages.  
Team collaboration and productivity: It helps team members understand functionality and use cases, improves communication, and reduces misunderstandings, leading to smoother collaboration and higher productivity. It also boosts the technical level of the team and contributes to talent retention.  
Easier onboarding of new professionals: Writing tests acts as living documentation, lowering the entry barrier for new professionals joining a team.
