faker

API Genie makes realistic values (names, emails, addresses, IBANs, dates…) with its own faker library. Its providers are named like those of faker.js (person.firstName, internet.email) and are used by:

• the x-faker (or x-apigenie-mock-faker) extension of schemas, in apigenie-server and data;
• @mock(faker:, args:) and graphql.fields.<field>.faker of the GraphQL mock;
• fake(name, ...arguments) of mock scripts and {{fake:name}} of gRPC templates;
• smart names: string properties called like email, first_name or city.

Arguments

A provider takes arguments by position or by name, and checks them: an argument it doesn’t take, of the wrong type, out of its bounds or not one of its choices is an error naming the provider and the parameter (faker: number.int: parameter min: expects an integer, not a string).

properties:
  owner: {type: string, x-faker: person.fullName}
  age: {type: integer, x-faker: {number.int: [18, 90]}}
  code: {type: string, x-faker: {string.alpha: {length: 6, casing: upper}}}
  email:
    type: string
    x-faker: {provider: internet.email, args: [Ada, Lovelace], options: {provider: example.org}}

Arguments are numbers, strings and booleans. Whole numbers given as decimals (JavaScript and YAML give 6.0) are integers.

Records

Some providers make related values together, as a record (an object): person.profile (a person’s sex, first and last names of that sex, full name, a username made of the names, an email of that username and an adult’s birth date), location.address (an address of one country, with its code and a time zone of it; city, state and postal code are of the country but not of each other), finance.card (an issuer’s number, verification value length and expiration), finance.currency and commerce.product. A record is an object in JSON responses and data, and its JSON text where the schema wants a string.

Countries

Names exist for 61 countries; addresses and phone numbers for 15 of them (US, PL, FR, DE, IT, RU, IN, FI, ES, CZ, UA, DK, BR, AU and EE). Providers taking a country use the USA’s data when not given one, except IBANs, BICs and national ids, which are then of a random country that has them. Usernames and emails are ASCII: names in Latin, Cyrillic or Greek letters are transliterated (Łukasz is Lukasz, Иван is Ivan); names in other scripts give usernames of American names.

Validity

IBANs have valid ISO 13616 check digits, routing numbers a valid ABA checksum, card numbers and IMEIs a valid Luhn check digit, and EAN and ISBN codes their check digits. National ids (person.ssn) are valid for Poland (PESEL), the USA, Spain (NIE) and the United Kingdom (National Insurance number), and only format-shaped for Germany, France, Italy and India. Bitcoin, Litecoin and Ethereum addresses and VINs are format-shaped.

Reproducibility

--seed repeats a run. Faker draws its values with algorithms of its own, so a seed gives the same faker values on every platform; the other choices of a mock (numbers, list lengths, which optional properties) repeat on the same platform. Relative dates (date.past, date.recent, birth dates) count from a reference time and repeat when it does too. Values may change between versions of API Genie.
