How to test an ETL Process – Basic Concept

The basic concept of ETL Testing and Data Warehouse Testing The answer lies in the understanding of an ETL process. An ETL process at its core reads data, applies a transformation on it and then loads the data. This can be represented by the following simplistic equation. Input Data + Transformation = Output Data The…


iCEDQ - ETL Testing Vs. Application

ETL Testing Vs. Application Testing – The Fundamental Difference

At the core, quality is the measurement of deviation between what is expected vs. actual. In quality assurance practice, we implement a set of tests to measure this deviation. The extent of the deviation indicates the quality of the software. In any application testing, there are three common terms that we will notice: Requirements Test…
