Introduction to ETL Testing:
ETL Testing tools increase IT efficiency and make data recovery from big data easier, allowing you to gain new insights. The tool itself includes strategies and guidelines for extracting and processing data, obviating the need for traditional, labor-intensive, and expensive programming methods. As a result, ETL testing is a critical component of big data testing. The conventional ETL was a crucial part of the data warehousing process. ETL's main goal was to extract data from a variety of sources, transform it according to business rules, and upload it to the target database. ETL for the traditional A process might take anywhere from two hours to a day. The ETL functions are primarily batch and relational in nature, and they were created and deployed using a well-established ETL technology.
ETL testing guarantees that data is transferred from disparate sources to a central data warehouse in strict accordance with transformation rules and that all validity checks are met. ETL Testing differs from database testing in that it is performed on data warehouse systems and is used to acquire relevant data for analytics and business intelligence.
ETL testing tools:
- Graphical interface
- Automatic code generation
- Built-in data connectors
- Content management facilities
- Sophisticated debugging tools
ETL Testing Challenges:
- Data that is incompatible or duplicated
- Data loss during the ETL procedure
- The inclusive testbed is not available.
- Testers do not have the ability to run ETL processes on their own since the volume and complexity of data is so large.
- Process and procedure flaws in the workplace
- Having trouble obtaining and generating test data
- Unstable testing conditions
- Information on the business flow is missing.
