Ranger - Contextual Data and Load Generator

Back Solutions

Ranger is contextual data and load generator. It consists of two modules: data generator and load generator.

Contextual data generator allows developers to quickly and easily define and create large number of objects whose attributes values and distribution reflect production environment. This module alone can be used for easier data creation for integration testing or to quickly populate the database with meaningful data.

Load generator is a tool that uses data generator (for obtaining the form, values, and the distribution of data) at its core and creates a load from it that can target, for example, a database or an API in order to do load testing. What makes it different from similar load testing tools is that actual load doesn't consist of randomly generated values. The user has control over both the load shape and data content. This way load generator can more accurately simulate production like conditions.
