The developer is tasked with implementing two new features for an existing application that serves hundreds of ski resorts globally. The application uses Python and Flask, and the previous developer has quit, causing delays. The new developer must work quickly to implement the desired changes without introducing bugs. However, there are no automated tests in place, making it challenging to ensure the changes don't break existing behavior unintentionally. A tool called CodiumAI is introduced that can generate a series of tests and provide an analysis of the code in simple English. By using CodiumAI, the developer can quickly capture the existing behavior of the code, set up a safety net with decent tests, and move forward with implementing the new features with more confidence. The tool reduces the time it takes to write missing tests and provides a direction for the development process.
