Testing in small increments is a crucial best practice when writing Karel programs, as it allows you to verify functionality at each step of your code. This incremental testing approach helps you identify and resolve issues early in the development process, making debugging easier and more efficient.

When you test small sections of code, you can focus on specific functions or commands, ensuring that each part behaves as expected before adding more complexity. This practice reduces the chances of introducing errors into the program and enhances the overall reliability of your code.

Additionally, working in small increments can prevent frustration when something does not work, as it narrows down the area of concern to a smaller scope. This methodology promotes a better understanding of how each component of your program interacts, leading to cleaner and more maintainable code.
