Faker is library for generating high-quality fake data, such as names, addresses and phone numbers. Faker is still under development, and will evolved in the coming months.

Using Faker is very easy.

• Versions < 4.0.0 require Java 8+
• Version 4+ require Java 11+

Let's generate a random person.

Person person = RandomPerson.get().next()

If we want a list of 20 random people, we would call:

List<Person> people = RandomPerson.get().listOf(20);

If you use Jackson to serialize a person, you'll see something like this:

{
  "firstName" : "PAM",
  "lastName" : "GALLINGER",
  "title" : "Carpet, Floor, and Tile Installer",
  "gender" : "FEMALE",
  "birthdate" : "1987-07-13T22:49:34.743000000Z",
  "age" : 30
}

Let's generate a random address.

Address address = RandomAddress.get().next()

If we want a list of 20 random addresses, we would call:

List<Address> addresses = RandomAddress.get().listOf(20);

If you use Jackson to serialize an address, you'll see something like this:

{
  "street" : "60 ENGLISH ST",
  "city" : "SAN FRANCISCO",
  "state" : "CA",
  "postalCode" : "94105"
}

The library is available on Maven Central.
