   • approach originates from the Agile manifesto principles and Extreme programming.
     • Step 1. Create precise tests. Developers need to create precise unit tests to verify the functionality of specific features.
     • Step 2: Correcting the Code. When a test fails, developers need to make the minimal changes required to correct the code so that it can run successfully when re-executed.
     • Step 3: Refactor the Code. Once the test runs successfully, check for redundancy or any possible code optimizations to enhance general performance.
