JSON Data Generator (blog post):

  • ACES, Inc. developed the generator with the following features from start to finish
  • Generate json documents that are defined in json themselves. This would allow us to take existing schemas, drop them in to the generator, modify them a bit and start generating data that looks like what we expect in our application
  • Generate json with random data as values. This includes different types of random data, not just random characters, but things like random names, counters, dates, primitive types, etc.
  • Generate a constant stream of json events that are sent somewhere
  • Generate events in a defined order, at defined or random time periods

“The ultimate reward and sense of accomplishment for any elite software engineer is when their code is found on the internet and easily reused and integrated into a different project by other software engineers.  Even better when the person that reused the code says Thanks!”
