Mockneat is an arbitrary data-generator open-source library written in Java.

It provides a simple but powerful (fluent) API that enables developers to create json, xml, csv and sql data programatically.

It can also act as a powerful Random substitute or a mocking library.

Example - A random dice roll

List<String> somePeople = names().full().list(10).get();

fmt("#{person} rolled: #{roll1} #{roll2}")
            .param("person", seq(somePeople))
            .param("roll1", ints().rangeClosed(1, 6))
            .param("roll2", ints().rangeClosed(1, 6))
            .accumulate(10, "\n")
            .consume(System.out::println);

System.out.println("\nWho wins ?\n");

(possible) Output:

Sal Clouden rolled: 3 3
Cinthia Myrum rolled: 1 5
Wyatt Imber rolled: 5 1
Fidel Quist rolled: 2 2
Brandon Scrape rolled: 6 4
Arlene Cesare rolled: 6 4
Brandie Sumsion rolled: 3 4
Norris Tunby rolled: 3 5
Kareem Willoughby rolled: 1 5
Zoraida Finnerty rolled: 1 6

Who wins ?

Example - A simple CSV

System.out.println("First Name, Last Name, Email, Site, IP, Credit Card, Date");

csvs()
  .column(names().first())
  .column(names().last())
  .column(emails().domain("mockneat.com"))
  .column(urls().domains(POPULAR))
  .column(ipv4s().types(CLASS_B, CLASS_C_NONPRIVATE))
  .column(creditCards().types(AMERICAN_EXPRESS, VISA_16))
  .column(localDates().thisYear())
  .separator(" ; ")
  .accumulate(25, "\n")
  .consume(System.out::println);
