Signature

generateWithConstraints( generatorFn: () => string, constraints: ValueConstraints = {}, ): : string

Summary

Repeatedly invokes a generator function until the result satisfies the given constraints (e.g. maxLength, native element validity).

Tags

#@param generatorFn - Zero-arg function that produces a random value#@param constraints - Optional element/length constraints to satisfy#@returns A value that passes validation, or empty string if `requireValidity` is set and no valid value is found

Source Code
