Accelerated Continuous Testing with Test Impact Analysis - Part 3

This post details the core mechanism of Test Impact Analysis (TIA) by explaining how it collects dynamic dependencies at the file level to determine which tests are affected by code changes. It elaborates on TIA's fallback logic when unknown file types are encountered and provides detailed configuration options for controlling TIA's behavior, including the use of `DisableTestImpactAnalysis`, `TIA_IncludePathFilters` for path-specific triggers, and `TIA_IncludePathFilters` with negation for ignoring specific file types. It also offers methods for validating TIA's effectiveness and encourages its adoption in PR workflows.
