LATdx runs your Apex tests, fingerprints what each one depends on, caches the results, and re-runs only the tests your changes affect.

LATdx is a caching test runner for Salesforce Apex. It runs on top of the sf CLI auth and sfdx-project.json workspace you already have, matching every result to the Apex source and everything it depends on. Change one class and the next run re-executes only the tests that reach it; everything else replays from cache.
