SDG: Search-based Synthetic Data Generator

Many testing activities, such as usage-based statistical testing, require the generation of synthetic testing data that can be used to build confidence in the reliability of the system under test. Generating such data is not a trivial task as the underlying data schemas are usually large, complex, and subject to numerous domain-related logical constraints. The ultimate goal of the SDG tool is to automatically generate such synthetic data.

System Requirements

  • Eclipse IDE (Mars or higher) [link].

  • Java Development Kit (JDK) 1.8.0 (or higher) [link].

  • Note that all the other required third-party libraries are included in the installation package.

  • We also recommend using the Papyrus modeling environment for building and managing models [link].

Demonstration Material

  • Profile for expressing the statistical characteristics of the test data [link].

  • Example of a domain model annotated with statistical information (TaxCard) [link].

  • OCL constraints expressing the logical validity of the data [link].

  • Example of a valid and representative test data sample generated using SDG [link].

Installation Material for SDG

  • The SDG tool can be found [here].

  • Installation and usage instructions can be found [here].
