1. Theoretical Study

   - Research TDD and BDD and explain their core principles in your own words. 

   - Compare the two methodologies and highlight the scenarios in which each is more suitable. 

 

2. Practical Implementation

   - Choose a programming language of your choice (Python, Java, JavaScript, etc.). 

   - The implementation must follow these steps: 

•     For TDD: 

       - Write a unit test before implementing the functionality. 

       - Run the test (it should initially fail). 

       - Write the minimal code necessary to make the test pass. 

       - Refactor the code while keeping the tests green. 

•      For BDD: 

       - Write a test scenario using a specific BDD framework (Cucumber, Behave, Jest+BDD, etc.). 

       - Implement the functionality based on the test specifications. 

 

3. Final Report

   - Describe the implementation process and any challenges encountered. 

   - Attach the source code and test results. 

   - Provide a personal conclusion on the advantages and disadvantages of each methodology based on your practical experience.
