ETL testing tools check that data was extracted, transformed and loaded correctly: row counts match, values survived each transformation, and nothing was dropped or duplicated between source and target. The main differences are how tests are written (no-code rules or SQL), which databases and warehouses they connect to, and whether they run inside a CI/CD pipeline.
