Testing complex data with Verify
summary
Verify is a .NET snapshot testing library that serializes complex objects to files, diffs runs against a checked-in baseline, and lets teams accept or reject changes with their normal diff tool. Workflow shows first-run failure creating a baseline, subsequent runs passing until a real change appears, and the library scrubs non-deterministic types like GUIDs and DateTimes. Integrations include Visual Studio/VS Code, CI pipelines, and an EF Core plugin to catch unexpected DB-request regressions.
