Big Data & Analytics Testing

Big Data & Analytics Testing

Big Data & Analytics Testing ensures the accuracy, reliability, and performance of data processing systems dealing with massive datasets. It involves validating data quality, performance, and security in environments like Hadoop, Spark, and cloud-based data lakes.

Big Data Testing refers to the validation of data ingestion, transformation, and retrieval processes in large-scale data systems. It ensures data integrity, scalability, and performance in analytics-driven applications.

Key Aspects of Big Data Testing:

• Data Quality Testing – Ensuring data accuracy, completeness, and consistency.
• ETL (Extract, Transform, Load) Testing – Validating data extraction, transformation logic, and loading processes.
• Performance Testing – Checking system response times, scalability, and throughput.
• Security Testing – Ensuring encryption, access control, and compliance adherence.
• Big Data Pipeline Testing – End-to-end validation of data movement from source to analytics.
