| + | The **Test Data Ingestion** module is designed to validate the integrity and reliability of the data ingestion pipeline by simulating real-world data flows and testing every step from extraction to loading. It rigorously checks that incoming data is correctly formatted, accurately structured, and free from anomalies or corruption before it progresses further downstream. By implementing comprehensive validation rules and consistency checks, the module acts as a quality gate, preventing faulty or incomplete data from impacting subsequent processing stages such as transformation, | ||
