Object

Generate object values.

dictionary

Signatures:

  • fc.dictionary(keyArb, valueArb)
  • fc.dictionary(keyArb, valueArb, {minKeys?, maxKeys?, size?, noNullPrototype?, depthIdentifier?})

with:

  • keyArbarbitrary instance responsible to generate keys
  • valueArbarbitrary instance responsible to generate values

  • size? — default: undefined morehow large should the generated values be?
  • noNullPrototype? — default: falseonly generate objects based on the Object-prototype, do not generate any object with null-prototype

set

Set of random size containing unique values generated by arb.

All the values in the set are unique. Comparison of values relies on SameValueZero which is the same comparison algorithm used by JavaScript's native Set. This means that -0 and +0 are considered equal, and NaN is considered equal to itself.

Signatures:

  • fc.set(arb)
  • fc.set(arb, {minLength?, maxLength?, size?, depthIdentifier?})

with:

  • arbarbitrary instance responsible to generate values
  • minLength? — default: 0minimal size (included)
  • maxLength? — default: 0x7fffffff moremaximal size (included)
  • size? — default: undefined morehow large should the generated values be?
  • depthIdentifier? — default: undefinedwhen specified, the set will impact the depth attached to the identifier to avoid going too deep if it already generated lots of items for current level

Usages:

fc.set(fc.nat());
// Examples of generated values:

with:

  • key? — default: fc.string()arbitrary responsible to generate keys used for instances of objects
  • depthSize? — default: undefined morehow much we allow our recursive structures to be deep?
  • maxDepth? — default: Number.POSITIVE_INFINITYmaximal depth for generated objects (Map and Set included into objects)
  • maxKeys? — default: 0x7fffffff moremaximal number of keys in generated objects (Map and Set included into objects)
  • size? — default: undefined morehow large should the generated values be?
  • withBigInt? — default: falseenable bigint - eg.: 1n
  • withBoxedValues? — default: falseenable boxed values - eg.: new Number(5)
  • withDate? — default: falseenable Date - eg.: new Date('2020-10-14T16:52:36.736Z')
  • withMap? — default: falseenable Map - eg.: new Map([['key', 'value']])
  • withNullPrototype? — default: falseenable objects not defining any prototype - eg.: Object.create(null)
  • withObjectString? — default: falseenable strings looking as string representations of JavaScript instances - eg.: "{}", "new Set([1])"
  • withSet? — default: falseenable Set - eg.: new Set([1, 2, 3])
  • withTypedArray? — default: falseenable typed arrays for ints, uints and floats - eg.: Int8Array.from([1, 2, 3])
  • withSparseArray? — default: falseenable sparse arrays - eg.: [1,,,3]
  • withUnicodeString? — default: falsechange the default for key and values so that they produce unicode strings with non-ascii characters
  • stringUnit? — default: undefinedcustomize the set of characters being used by the string arbitrary — shadowed by stringUnit
  • values? — default: booleans, numbers, strings, null and undefinedarray of arbitraries producing the root* values - *non-object ones
