Grigorii Sedelnikov, an Automation QA engineer at EXANTE, explains how his team moved an order risk assessment service out of a monolith and migrated automated tests to it. Along the way, a test audit uncovered false positives, coverage gaps and documentation inaccuracies, and regression runs became much faster. The author also explains why AI helped with analysis, but the team did the migration by hand, and how that experience laid the groundwork for future automation.
