Unit testing usually delivers the best initial ROI. Unit tests are quick to write, run quickly, and immediately identify basic code errors before larger testing layers are even needed. QA automation (end-to-end or integration testing) offers comprehensive coverage, but creating and maintaining it across user workflows is heavier up front.
