Avoid files with too many functions or methods

How we detect

CAST Highlight counts the number of functions/methods found per file. Depending on thresholds based on benchmark analysis of reference applications, CAST Highlight will decrement the capital of points for the scanned file where the code insight occurs.

Why you should care

For maintainability and code readability purposes, it is a good practice to limit the number of functions/methods per file.
