Under The Hood

IntelliPest leverages the nikic/PHP-Parser package in order to parse your Pest.php as an AST (Abstract Syntax Tree).

This enables it to extract call chains to Pest's configuration API (namely pest(), uses(), expect()).

Based on these function calls and the arguments you pass to them (mainly TestCase classes and Traits), IntelliPest maps those to an internal data structure.

As a final step, IntelliPest takes all of this analyzed data and generates a PHP helper file with the help of templates.
