ETL Testing

Reposting from my Answer from SQA stackexchange

Sharing my learning's on ETL Testing
  • How errors are logged in case of failures in pulling data. Example - Network connectivity is lost while pulling data, does the job retry ?
  • Is it possible to configure toggle select only few tables to pull data to be pulled by ETL jobs
  • Test with real production data. Typically volume of data in BI system is Tera Bytes of Data
  • Look for Data Quality Issues - How Application handles nulls, blank data, Duplicate data
  • Slowly Changing Dimensions - How Changes to dimension tables are handled, Depending on type SCD 1, SCD 2 you can decide to test it the way it works
  • Manually when you have failure in pulling data in one of tables, How does it behave. Example - from source system one of table is dropped. SSIS package is not updated. In this scenarios how error is handled
