ETL Testing Services

An ETL tool Extracts the data from heterogeneous data sources (like relational databases, CSV, spreadsheets, etc.), Transforms the data (applying calculations, mapping data fields, etc.), and Loads it into a Data Warehouse system. You can then use various Business Intelligence (BI) tools to generate meaningful reports, dashboards, and visualizations.

Support for Big Data is growing continually and exponentially. Most ETL tools now provide data integration solution for Big Data.

The primary objective of ETL testing is to identify and mitigate data defects and general errors that occur before processing of data for analytical reporting. ETL can pollute the entire system if done wrong.
Being industry experts, we have the acumen in performing activities ranging from Reviewing Data model right up to Data integrity and quality checks in the target system.

Our ETL Testing Services

At Codoid, we understand the perils that your Data Warehouse can face. With the know-how of both proprietary and open-source tools, our ETL testing services include –

Production Validation ETL Testing
It’s essential that your data warehouse is of maximum competitive advantage to your business. Our ETL Testing and Validation techniques ensure Production reconciliation so that your business information is correct, reliable and consistent.

Application Upgrade Testing
Technology changes every day. And your Data warehouse must adapt to the changes to be compliant, embrace new security & performance upgrades. Considerable effort in pre and post upgrade can be saved with our systematic testing approach towards migrating previous data into the new repository and the like.

Validation/Source-to-target Testing
Data correctness is a vital check to be performed during and post the data transformation process. Our automated testing procedure not only validates the end-to-end data but also outlines remediation to prevent future data corruption.

Testing for Data Completeness
Once the data is validated with the help of Validation testing, we verify that all the data is accurately loaded into the data warehouse by comparing validation counts, aggregates, and Spot checks between random Actual and Target data on a timely basis.

Metadata Testing
Metadata protects the Data quality. Our automated metadata testing procedure includes close check on Data type, Data length, Index /Constraint, etc.

Data Transformation Testing
Data transformation testing can get complicated at times since multiple SQL queries may need to be run to verify all transformation rules conform to the business rules. Our techniques ensure saving time on this tedious task.

Quality Testing/Reference & Syntax tests
Our data quality testing services help prevent syntax issues (dirty data), and errors caused due to incorrect reference types (data model). Data quality is affected due to bad data (Ex- invalid characters, invalid patterns, etc.) or Data model (Ex- data types, precision, Null, etc.)

Navigation/GUI Testing
Navigation/GUI testing is equally important to ensure all aspects of front-end reports are covered, and corrective measures are applied.
