ETL Testing Course in Hyderabad
Validate data pipelines and warehouses with SQL-based ETL and data testing
The ETL Testing course teaches you to verify that data moves correctly from source systems into data warehouses and reports. You start with SQL, data warehousing and ETL concepts, then learn the ETL testing life cycle, requirement and source-to-target mapping analysis, test planning and test case design, and the main types of data testing: record counts, data completeness, transformation logic, duplicates, null and referential integrity checks, reconciliation, slowly changing dimensions, incremental and CDC loads, data quality and performance. You write SQL validation queries, compare datasets with Python and pandas, automate repeatable checks with pytest and data quality tools such as Great Expectations or dbt tests, test BI reports, and log defects in Jira. You also practise on cloud platforms such as BigQuery, Snowflake or Redshift. The course suits testers, graduates and SQL professionals who want to move into data and QA roles; basic SQL helps. Classes run in Ameerpet, Hyderabad, and in live online batches.

- •Outcome: Document tests that others can execute
Source-to-Target Validation

Incremental, CDC & Reconciliation Testing
- •Testing initial versus incremental loads and late-arriving data
- •Upserts, soft deletes and rerun or restart behaviour
- •Reconciliation between source, staging and warehouse
- •Lab: Test an incremental load with changed, new and deleted rows
- •Outcome: Confirm repeatable, correct loads
Python for Data Validation & Automation
