Etl Automation Testing Tools
ETL Testing: Essential to Effective Data Warehousing Building a data warehouse is a major undertaking that's expected to yield substantial business benefits in order to justify the cost and effort. To ensure that your project lives up to expectations, ETL testing must be front and center, particularly in the all-important early stages of the project.
A Unit testing is a Level of Testing where smallest part of individual unit / component (called unit) is tested to determine if they are fit for use. The unit test cases writing and execution is done by the developer (not the tester) to make sure that individual units are working as expected.

What is ETL Testing? ETL testing seeks to ensure that transfer of data from heterogeneous sources to the central warehouse occurs without data loss, with strict adherence to transformation rules, and in compliance with all validity checks. Effective ETL testing should detect early on any problems with the source data as well as any inconsistencies or ambiguities in the business rules that are intended to guide data transformation and integration. ETL testing should continue as production gets underway, to ensure that the extraction, transformation, and loading processes are going as planned and that the result is warehoused data that's consistent, accurate, and complete.
