Reports testing

Reports Testing :

In last post (BI testing – Part 1) we discussed about the ETL process.  In this post, let us discuss more about testing the BI reports.
Report is a consolidated information presented in the user friendly format. Reports enables users to gain insight into the business data, metrics and take decisions based on the intelligence gained from this data.
Typically BI reporting tools have capability to create huge number of reports presenting complex information in multiple user friendly formats. Broadly, reports can be of 2 types – Canned reports are the ones which are predefined and created automatically by the system at scheduled intervals, Ad-hoc or On demand reports are created by users as per their needs. The reports can be static providing the required information in one go or they can be dynamic where user can interactively drill down, filter information or  change data representation etc.
Key elements in report testing are to check the report generation process, data content accuracy, data consolidation and calculations (sums, averages , section wise breaking etc) correctness , formatting and layout of contents, conversion of reports to multiple formats,  interactive features  and usability in terms of ability to quickly derive intelligence from the data.

It is important for tester to have knowledge of SQL, insight into the BI tool’s reporting features and correct understanding of customer expectations in order to effectively test the reporting functionality.
BI testing is a continuously growing and so are the opportunities for the testers in this specialized and niche testing area.
