Data Quality Model-based Testing of Information Systems: the Use-case of E-scooters

Abstract

The paper proposes a data quality model-based testing methodology aimed at improving testing methodology of information systems (IS) using previously proposed data quality model. The solution supposes creation of a description of the data to be processed by IS and the data quality requirements used for the development of the tests, followed by performing an automated test of the system on the generated tests verifying the correctness of data to be entered and stored in the database. The generation of tests for all possible data quality conditions creates a complete set of tests that verify the operation of the IS under all possible data quality conditions. The proposed solution is demonstrated by the real example of the system dealing with e-scooters. Although the proposed solution is demonstrated by applying it to the system that is already in use, it can also be used when developing a new system.
