Increase test coverage by leveraging powerful synthetic data generation mechanism to create the smallest set of data needed for comprehensive testing as well as for specific business case scenarios. We set up the generator for [CountRequest] and [PaymentAmount] fields in the same way, according to the generated data type: In the first case, we set the values’ range of 0 to 2048 for [CountRequest]. by most of frameworks and tools). Overall, the particular synthetic data generation method chosen needs to be specific to the particular use of the data once synthesised. Data masking or data obfuscation is the process of hiding original data with modified content but at the same time, such data must remain usable for the purposes of undertaking valid test cycles. It is important to note that the generator automatically determines which generation type it needs to apply to every field. We’ve also provided scripts for changing the data from the production database and synthetic data generation. Data generation tools (for external resources) Full list of tools. The goal of synthetic data generation is to produce sufficiently groomed data for training an effective machine learning model -- including classification, regression, and clustering. In order to generate various sets of data, you can use a gamut of automated test data generation tools.
