·   To test all Informatica processes this included:  unit, system , and parallel testing

·   Creation and/or update the ongoing maintenance of test process documentation and test plans

·   Was part of the development team that created a suite of test data (both input files and expected results) that fully exercises data validation (detecting and rejecting bad data) and actual ETL functionality (properly processing good data, i.e., transformations, calculations, and derivations)

·   Ran the regular (weekly) process in which the test data suite will be used to validate each new ETL build

·   Ran the process by which any additions/modifications to the MicroStrategy reports will be validated before release to production

·   Coordinated  the ETL and MicroStrategy administrators on the development/test/production promotion process

·   Wrote Oracle PL/SQL queries to validate that actual test results that matched the expected results

·   Ran the process by which incremental data from existing clients are loaded and verified before release to production, this was done with a variety of sources, including SQL Server databases, Excel worksheets, ANSI file files and FTP processes.

·   Create and update the defect tracking process, by which defects were prioritized and scheduled for resolution, including preparation of reports that summarize overall project status for review by the team
