Filtering GitHub actions by changed files

The blog post discusses an approach to optimizing GitHub Actions by filtering the execution of tests based on specific file changes. It provides insights into using `dorny/paths-filter` to determine when to run tests in a CI/CD pipeline, incorporating conditions, debugging experiences, and improvements made to ensure tests only run when necessary. The author shares personal trial-and-error experiences, including the impact of YAML syntax on expression evaluation in GitHub Actions, aiming to save others from similar debugging challenges.
