This was created as a solution for the Featherweight Design Component Library to dynamically find all component test suites based on existing \*.spec.ts files. Cypress tests in the library are parallelized through a GH Action matrix strategy. This required maintaining an array of test suites (e.g. ['Button', 'Checkbox']) for two different GH workflows which was tedious and prone to error.

This GH action allows us to pass a target directory and file glob to dynamically determine which tests suites we should run, automatically detecting when test suites are removed or added.

Required The file glob of any files for which you want the parent directory name (e.g. *.spec.ts, **/*.js, etc.).

The location where we should search for files that match the file-glob (e.g. /cypress, /, etc.). Default / (root).

Whether or not to return unique values when duplicates may be possible. Default "true".

An array of directory names that house any matching files (e.g. ['Button', 'Components', ...]).
