Fake Data Module for Mendix


Want to generate fake data in Mendix? The Fake Data Module for Mendix does this for you. It uses the popular Faker library.


Java Actions


  • GenerateDateBetween - generate a date between two dates


  • GenerateDecimalBetween - generate a decimal between two numbers
  • GenerateNumberBetween - generate an integer/long between two numbers
  • GenerateNumberDigits - generate an long number with an X amount of digits


The following Entities can be created:

  • App
  • Artist
  • Cat
  • Commerce
  • Name

Please have a look at the Domain Model in the module for all attributes that are set.


  • GenerateFakeString - generate a string from a predefined list of types, like hashes, quotes
  • GenerateQuote - generate a string that holds a quote from one of the predefined movies/characters
  • GenerateRandomColorHex - generate a color in HEX format
  • GenerateRandomRegexString - generate a string based on a Regex. More information can be found here: https://github.com/mifmif/Generex
  • GenerateRandomString - generate a string based on a mask. This mask will replace any ? with a letter and any # with a number.
